语法相关
1.1 byte 数组
byte[] writeData = new byte[2];
byte[] readData = new byte[1];
1.2 string 数组
string[] charger_stat = new string[] {

“Ready”,“Charge in progress”,“Charge done”,“Fault”,
};
1.3 string 二维数组
public static String[,] g_select_string = {

{“000–USB2.0 host with 100mA current limit”, “001-USB3.0 host with 150mA current limit”,“010–USB2.0 host with 500mA current limit”,“011–USB3.0 host with 900mA current limit”,“100–Charger with 1500mA current limit”,“101-Charger with 2000mA current limit”,“110-External ILIM current limit”,“111-No input current limit with internal clamp at 3A (PTM MODE)”},
{ “50 mA”,“75 mA”, “100 mA”, “125 mA”,“150 mA”,“175 mA”,“200 mA”,“225 mA”},
{ “Normal charge current set by 03h”, “Low charge current setting 330mA”, “NULL”,“NULL”,“NULL”,“NULL”,“NULL”,“NULL”},
{ “00–0.75 hour fast charge”, “01–6 hour fast charge”, “10–9 hour fast charge”,“11–Disable safety timers”,“NULL”,“NULL”,“NULL”,“NULL”},
};

1.4 string 数组list
ArrayList g_label1_str = new ArrayList(label1_str); // 初始化

int index = g_label1_str.IndexOf(label1.Text); // 通过字符串找下标

1.5 字符串处理
1.5.1 substring
截取子串，第一个参数从第几个字符开始，第二个参数，长度
for (int k = 0; k <= 7; k++)
{
dataGridView1[k + 2, i].Value = d.Substring(k, 1);
}
1.5.2 tostring
val = (k * 0.02 + 3.5).ToString(“F2”) + " V"; // 转化成2位小数的float

addr = val.ToString(); // 转化成字符串
1.5.3 string ascii 转化
//ASCII转字符串
public static string Ascii2Str(byte[] buf)
{
return System.Text.Encoding.ASCII.GetString(buf);
}
//字符串转ASCII
public static byte[] str2ASCII(String xmlStr)
{
return Encoding.Default.GetBytes(xmlStr);
}
1.6 Convert
字符串为0xA1 时，第二个参数不写成16 ，会出错。意思是16进制的字符串
row_index = Convert.ToByte(label2.Text.Substring(1, 2), 16) / 16;

Convert 成int 后在转换成16进制的字符串，X2 表示2位，大写。
Convert.ToInt32(Params[i + 1]).ToString(“X2”)
转化成二进制，第二个参数是2.
Convert.ToString(Convert.ToInt32(Params[i + 1]), 2).PadLeft(8, ‘0’); // PadLeft(8,‘0’),不足8 位，左补0

常用基础组件
2.1 combox
2.1.1 定义及样式
ComboBox[] Combo = new ComboBox[15];
样式如下：

2.1.2 添加下拉框的元素
for (k = 0; k < 8; k++)
{
val = (k * 0.08 + 4.2).ToString(“F2”) + " V";
Combo[i].Items.Add(val);
}

AutoRcomboBox.Items.Add(“Auto Read OFF”);

comboBox1.Items.AddRange(pmbus_datagrid_alphabet_command_str); // 添加字符串数组

2.1.3 其他用法
多个中断处理函数合成一个通用的
for (i = 0; i < 8; i++)
{
Combo[i].SelectionChangeCommitted += new EventHandler(ComboBox_SelectionChange); //Combo内容改变事件
Combo[i].MouseMove += new MouseEventHandler(comboBox_MouseMove); //鼠标进入Combo事件
Combo[i].MouseLeave += new EventHandler(comboBox_MouseLeave); //鼠标离开Combo事件
Combo[i].MouseClick += new MouseEventHandler(comboBox_MouseClick); //鼠标点击Combo事件
Combo[i].Height += 20;
}

ComboBox_SelectionChange函数的处理

private void ComboBox_SelectionChange(object sender, EventArgs e)
{
for (r = 0; r < 8; r++)
{
if (sender == Combo[r]) // 得到当前是哪一个combox
{
break;
}
}
}

直接赋值文本
comboBox1.Text = “哈哈哈哈”
SerialNumcomboBox.SelectedIndex = 1；//显示第一个元素
清除元素
comboBox1.Items.Clear();
获取显示的元素字符
Readindx = AutoRcomboBox.SelectedItem.ToString();

for (int i = 0; i < 8; i++) //多字节中Combo颜色复位
{ Combo[i].BackColor = SystemColors.Window; }
2.2 label

{
if(e.Node == treeView1.TopNode.Nodes[0])
{

{
if (e.Node.Level == 1) //判断子节点才响应
{
int index = g_map_arr.IndexOf(e.Node.Text);
}
}
2.16 dataGridView
2.16.1 定义及样式
this.dataGridView1 = new System.Windows.Forms.DataGridView();

2.16.2 基本用法

dataGridView1.Columns[0].DefaultCellStyle.SelectionBackColor = SystemColors.Control;
dataGridView1.Columns[0].DefaultCellStyle.SelectionForeColor = Color.Black;
dataGridView1.Columns[1].DefaultCellStyle.SelectionBackColor = SystemColors.Window;

dataGridView1.DefaultCellStyle.SelectionBackColor = Color.White; // 颜色相关
dataGridView1.DefaultCellStyle.SelectionForeColor = Color.Black; // 颜色相关

for (i = 2; i <= 9; i++)
{ dataGridView1.Columns[i].DefaultCellStyle.SelectionBackColor = Color.Yellow; }
dataGridView1.AdvancedColumnHeadersBorderStyle.Top = DataGridViewAdvancedCellBorderStyle.InsetDouble;
dataGridView1.MultiSelect = false;
dataGridView1.ColumnHeadersHeight = comboBox5.Height * 15 / 10;

4）单元格的上下左右的边框线式样的单独设定
CellBorderStyle只能设定单元格全部边框线的式样。要单独改变单元格某一边边框式样的话，需要用到DataGridView.AdvancedCellBorderStyle属性。如示例：
’ 单元格的上边和左边线设为二重线
’ 单元格的下边和右边线设为单重线
DataGridView1.AdvancedCellBorderStyle.Top = _
DataGridViewAdvancedCellBorderStyle.InsetDouble
DataGridView1.AdvancedCellBorderStyle.Right = _
DataGridViewAdvancedCellBorderStyle.Inset
DataGridView1.AdvancedCellBorderStyle.Bottom = _
DataGridViewAdvancedCellBorderStyle.Inset
DataGridView1.AdvancedCellBorderStyle.Left = _
DataGridViewAdvancedCellBorderStyle.InsetDouble
同样，设定行头单元格的属性是： AdvancedRowHeadersBorderStyle，设定列头单元格属性是：AdvancedColumnHeadersBorderStyle。

for (i = 0; i < (this.dataGridView1.Columns.Count); i++)
{
this.dataGridView1.Columns[i].SortMode = DataGridViewColumnSortMode.NotSortable;// 设置单元不可插入
this.dataGridView1.Columns[i].Width = dataGridView1.Width / 12; // 设置单元格宽度
if (i < (this.dataGridView1.Columns.Count - 2))
{

    for (int j = 0; j < this.dataGridView1.Rows.Count; j++)
    {
        dataGridView1.Rows[j].Cells[i].Value = "0";         // 设置单元格value
        dataGridView1.Rows[j].Height = comboBox5.Height;   // 设置单元格高度
    }
}
else
{

    dataGridView1.Columns[10].HeaderText = "";
    dataGridView1.Columns[11].HeaderText = "";
   
    for (int j = 0; j < this.dataGridView1.Rows.Count; j++)
    {
        dataGridView1.Rows[j].Cells[10].Value = "R"; 
        dataGridView1.Rows[j].Cells[11].Value = "W";
        dataGridView1.Rows[j].Height = comboBox5.Height * 15 / 10;
    }
   
    for (int j = 0; j < this.dataGridView1.Rows.Count; j++)
    {
        string st = j.ToString("X2");
        dataGridView1.Rows[j].Cells[0].Value = st;
    }
}

}
dataGridView1.AllowUserToAddRows = false; // 不允许新增行
dataGridView1.AllowUserToDeleteRows = false; // 不允许删除行
dataGridView1.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter; //value 对齐方式

// 直接设置单元格的背景色
{ dataGridView1[i, reg].Style.BackColor = Color.Yellow; }

//点击事件

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
//-------------------------------------------Data列单击--------------------------------------------------------------------//

if (e.ColumnIndex == 1 && e.RowIndex >= 0)   //判断行列的下标
{
    dataGridView1.Columns[1].ReadOnly = false;                
    dataGridView1.CurrentCell = dataGridView1[e.ColumnIndex, e.RowIndex];
    dataGridView1.BeginEdit(true);  // 可以编辑
    dataGrid_lastvalue = dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
}
 //-------------------------------------------内容单击------------------------------------------------------------------------//

if (e.ColumnIndex >= 2 && e.ColumnIndex <= 9 && e.RowIndex >= 0)
{
  
 }

//-------------------------------------------R列单击------------------------------------------------------------------------//
if (e.ColumnIndex == 10 && e.RowIndex >= 0 && e.RowIndex < 7)
{

}

//-------------------------------------------W列单击------------------------------------------------------------------------//
if (e.ColumnIndex == 11 && e.RowIndex < 7 && e.RowIndex >= 0) 
{
        
}

}

//编辑完成后事件
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{

}

private void dataGridView4_Paint(object sender, PaintEventArgs e)
{
//Offsets to adjust the position of the merged Header.
int heightOffset = -5;
int widthOffset = 0;
int xOffset = 0;
int yOffset = 4;

//Index of Header column from where the merging will start.
int columnIndex = 0;

//Number of Header columns to be merged.
int columnCount = 3;

//Get the position of the Header Cell.
Rectangle headerCellRectangle = dataGridView4.GetCellDisplayRectangle(columnIndex, 0, true);

//X coordinate of the merged Header Column.
int xCord = headerCellRectangle.Location.X + xOffset;

//Y coordinate of the merged Header Column.
int yCord = headerCellRectangle.Location.Y - headerCellRectangle.Height + yOffset;

//Calculate Width of merged Header Column by adding the widths of all Columns to be merged.
int mergedHeaderWidth = dataGridView4.Columns[columnIndex].Width * columnCount + widthOffset;

//Generate the merged Header Column Rectangle.
Rectangle mergedHeaderRect = new Rectangle(xCord, yCord, mergedHeaderWidth, headerCellRectangle.Height + heightOffset);

//Draw the merged Header Column Rectangle.
e.Graphics.FillRectangle(new SolidBrush(Color.LightBlue), mergedHeaderRect);

//Draw the merged Header Column Text.

判断串口是否打开
if (!serialPort1.IsOpen)
{
timer3.Enabled = false;
MessageBox.Show(“Serial port is not opened!”, “SGMICRO”, MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}

串口热插拔
protected override void WndProc(ref Message m)
{
if (m.Msg == 0x0219)
{//设备改变
if (m.WParam.ToInt32() == 0x8004)
{//usb串口拔出

        toolStripStatusLabel1.Text = "Dongle offline !!!";
        toolStripStatusLabel1.ForeColor = Color.Red;
        string[] ports = System.IO.Ports.SerialPort.GetPortNames();//重新获取串口
        SerialNumcomboBox.Items.Clear();//清除comboBox里面的数据
        SerialNumcomboBox.Items.AddRange(ports);//给comboBox1添加数据
        if (OpenSerialbutton.Text == "Close Serial")
        {//用户打开过串口
            if (!serialPort1.IsOpen)
            {//用户打开的串口被关闭:说明热插拔是用户打开的串口
                OpenSerialbutton.Text = "Open Serial";
                serialPort1.Dispose();//释放掉原先的串口资源
                SerialNumcomboBox.SelectedIndex = SerialNumcomboBox.Items.Count > 0 ? 0 : -1;//显示获取的第一个串口号
            }
            else
            {
                SerialNumcomboBox.Text = serialPortName;//显示用户打开的那个串口号                           
            }
        }
        else
        {//用户没有打开过串口
            SerialNumcomboBox.SelectedIndex = SerialNumcomboBox.Items.Count > 0 ? 0 : -1;//显示获取的第一个串口号
        }
    }
    else if (m.WParam.ToInt32() == 0x8000)
    {//usb串口连接上

        toolStripStatusLabel1.Text = "Dongle online !!!";

        }
    }
}
base.WndProc(ref m);

3. 进阶用法
3.1 弹出新界面
// otp
// 点击弹框的图标按钮，弹出otp 的界面
private void toolStripButton11_Click(object sender, EventArgs e)
{
Form2 otp_form = new Form2();
otp_form.ShowDialog();
}

3.2 点击按钮安装驱动
private void Driverbutton_Click(object sender, EventArgs e)
{
string str = System.Environment.CurrentDirectory;
//str = str + “\驱动”;
str = str + “\SETUP”;
System.Diagnostics.Process.Start(str);
}
3.2 加载配置文件
//load config
private void button6_Click(object sender, EventArgs e)
{
int row_index, column_index = 0;
//byte[] new_value;
OpenFileDialog ofd = new OpenFileDialog();
ofd.Reset();
ofd.Title = “Load Register”;
ofd.FileName = “”;
ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
ofd.Filter = “.txt|.txt”;
ofd.ValidateNames = true; //文件有效性验证ValidateNames，验证用户输入是否是一个有效的Windows文件名
ofd.CheckFileExists = true; //验证路径有效性
ofd.CheckPathExists = true; //验证文件有效性
ofd.RestoreDirectory = true;

try
{
    if (ofd.ShowDialog() == DialogResult.OK)
    {

        // 读入所有行
        string[] lines = File.ReadAllLines(ofd.FileName);
        // 点列表集合
        // List<Point> points = new List<Point>();
        // 让过第一行，从第二行开始处理
        for (int i = 1; i < lines.Length - 1; i++)
        {
            string line = lines[i];
            // 拆分行
            string[] v = line.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
            if (i == lines.Length - 2)
                MessageBox.Show(v[1]);
            row_index = (i + 0x23) / 16;
            column_index = (i + 0x23) - 16 * row_index + 1;
            byte old_value = Convert.ToByte((string)dataGridView1[column_index, row_index].Value, 16);
            byte new_value = Convert.ToByte(v[1], 16);
        
            if (old_value != new_value)
                dataGridView1[column_index, row_index].Style.BackColor = Color.MediumSeaGreen;
            dataGridView1[column_index, row_index].Value = v[1];
        }

    }
}
catch (Exception)
{
    MessageBox.Show("Invalid Register Format!", "SGMICRO", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

}

3.2 保存配置文件

//save config
private void button7_Click(object sender, EventArgs e)
{
string Save;
int row_index, column_index = 0;
// uint t;
//begin
Save = “17 00 00”;

for (int i = 0x24; i < 0xA6; i++)
{
    row_index = i / 16;
    column_index = i - 16 * row_index + 1;

    // t = mStrToBcd(Convert.ToString(dataGridView1.Rows[i].Cells[1].Value));
    Save += ("\r\n" + i.ToString("x2").ToUpper() + " " + dataGridView1[column_index, row_index].Value + " " + "FF");
}

//end
Save += "\r\nC2 F5 00";
SaveFileDialog dlg = new SaveFileDialog();
dlg.Title = "Save Register";
dlg.Filter = "*.txt|*.txt";//文件筛选器
dlg.AddExtension = true;//保存文件时自动加扩展名
dlg.FilterIndex = 1;//文件筛选器的索引,1为txt
dlg.RestoreDirectory = true;
if (dlg.ShowDialog() == DialogResult.OK)
{
    StreamWriter sw = new StreamWriter(dlg.FileName, false, Encoding.UTF8);
    sw.Write(Save);   // \r\n为换行
    sw.Close();
}

}
