下面是使用代码的DataTable

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.IO; 


namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 

      bool flag = this.openFileDialog1.ShowDialog() != DialogResult.Cancel; 
      if (flag) 
      { 
       DataTable dt = new DataTable(); 
       dt.Columns.Add("Col A", typeof(string)); 
       dt.Columns.Add("Col B", typeof(string)); 

       try 
       { 
        StreamReader streamReader = new StreamReader(openFileDialog1.FileName); 
        dataGridView1.AllowUserToAddRows = false; 
        string text = ""; 
        for (text = streamReader.ReadLine(); text != null; text = streamReader.ReadLine()) 
        { 
         string[] array = text.Split(new char[] { ':' }); 
         dataGridView1.Rows.Add(array); 
        } 
        streamReader.Close(); 
       } 
       catch (Exception err) 
       { 
        MessageBox.Show("Error" + err.Message); 
       } 

       dataGridView1.DataSource = dt; 
      } 
     } 
    } 
}
