C#

string csvFile = @"C:\Documents and Settings\aavprasad\Desktop\test.csv";
           string[] lines = File.ReadAllLines(csvFile);

           var values = lines.Select(l => new { FirstColumn = l.Split(',').First(), Values = l.Split(',').Skip(1).Select(v => int.Parse(v)) });

           dataGridView1.DataSource = values.ToList();

Call this method.

C#

using System.Linq;
       private void readCSV()
       {
           string csvFile = @"C:\Documents and Settings\aavprasad\Desktop\test.csv";
           string[] lines = File.ReadAllLines(csvFile);

           var values = lines.Select(l => new { FirstColumn = l.Split(',').First(), Values = l.Split(',').Skip(1).Select(v => int.Parse(v)) });
            GridView.DataSource = values.ToList();
            GridView.DataBind();

       }
