推荐答案

我在按钮点击事件上做了这个.

I have done this on button click event.

 private void button1_Click(object sender, EventArgs e)
        {
            System.IO.StreamReader file = new System.IO.StreamReader("D:\\test.txt");
            string[] columnnames = file.ReadLine().Split(' ');
            DataTable dt = new DataTable();
            foreach (string c in columnnames)
            {
                dt.Columns.Add(c);
            }
            string newline;
            while ((newline = file.ReadLine()) != null)
            {
                DataRow dr = dt.NewRow();
                string[] values = newline.Split(' ');
                for (int i = 0; i < values.Length; i++)
                {
                    dr[i] = values[i];
                }
                dt.Rows.Add(dr);
            }
            file.Close();
            dataGridView1.DataSource = dt;
        }

这是文本文件:

这里是输出:

只需根据您的需要进行更新.在文本文件中定义列名或在网格视图中默认

Just update according to your need. Define Column name in text file or default in grid view
