这里是我在使用C#过程中用到的一些控件的常用且简单的使用方法的总结
1.textBox
 textBox5.Text = Convert.ToString(add(Convert.ToInt32(textBox1.Text),Convert.ToInt32(textBox2.Text)));
 
 textBox5.Text 的类型是string所以要把其他类型的转换成string。
 
 
2.
浏览读取文件按钮 OpenFileDialog
保存文件按钮 saveFileDialog
 
        String fileName;
        //String folderName;
        String extendedName;
        String inputHanFileName;
        string pinYinResultFileName;

        private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();                //new一个方法
            ofd.InitialDirectory = Environment.GetFolderPathEnvironment.SpecialFolder.MyDocuments); 
            ofd.ShowDialog();          
            fileName = ofd.FileName;                //获得选择的文件路径
            textBox3.Text = fileName;
            extendedName = Path.GetExtension(fileName);       //获得文件扩展名
            inputHanFileName = Path.GetFileName(fileName);           //获得文件名
        }
 
        private void button2_Click(object sender, EventArgs e)
        {
           
            saveFileDialog1.InitialDirectory = Application.ExecutablePath;
            saveFileDialog1.Filter = "word Files(*.doc)|*.doc|All Files(*.*)|*.*";
            saveFileDialog1.OverwritePrompt = true;
            saveFileDialog1.ShowDialog();
            pinYinResultFileName = saveFileDialog1.FileName;
            textBox4.Text = pinYinResultFileName;
        }
 
3.radioButton1
radioButton1.Checked表示该按钮是否被选中，返回布尔值
           //if(radioButton1.Checked)
            //{
            //    textBox1.Text = "1";
            //}
            //else if(radioButton2.Checked)
            //{
            //    textBox1.Text = "2";
               
            //}
 
点击按钮1 和按钮2 即可以出现读取、保存对话框的情况~
