C#读取TXT文件并放入二维数组，拆分成两个一维数组并在两个文本框中显示

本文介绍了一个使用C#从指定路径读取文本文件，并将文件内容解析为二维数组的方法。通过FileStream和StreamReader读取文件，利用Split方法按特定字符分割字符串，最终将数据分别填充到两个文本框中。

private void button1_Click(object sender, EventArgs e)//读取文件到二维数组，放入两个文本框中
{
int row = 0;//行
int col = 0;//lie
FileStream fs;
string path = “E:\C##CX\C#TT\TEXT2.txt”;
textBox3.Text = “当前文件夹位置是:” + “\r\n” + path;
fs = new FileStream(path, FileMode.Open, FileAccess.Read);
StreamReader sr = new StreamReader(fs);
while (!sr.EndOfStream)
{
string[] arr = sr.ReadLine().Split(’ ');
col = arr.Length;
//textBox5.Text = “\r\n”;

    int[] a = new int[col / 2];
    double[] temp = new double[col];
    double[] ai = new double[col / 2];
    double[] aj = new double[col / 2];
    for (int x = 0; x < col; x++)
    {
        temp[x] = Convert.ToDouble(arr[x]);
        if (x % 2 == 0)
        {
            for (int i = 0; i < col / 2; i++)
            {
                ai[i] = temp[x];
                textBox1.Text = textBox1.Text + ' ' + ai[i] + "\r\n";
                //int l =  textBox1.Text.Length;
            }
        }
        else
        {
            for (int i = 0; i < col / 2; i++)
            {
                aj[i] = temp[x];
                textBox4.Text = textBox4.Text + ' ' + aj[i] + "\r\n";
            }
        }
    }
    int count = this.textBox1.Lines.GetUpperBound(0);
    for (int d = 1; d < count + 1; d++)
    {
        string rr = Convert.ToString(d);
        //textBox5.Text = textBox5.Text + rr + "\r\n";
    }
}
row++;
Console.WriteLine("\n");
