Solution 2

try it

C#

DataTable dt1 = new DataTable();
dt1 = ds.Tables[0];
for (int i = 0; i < dt.Columns.Count;i++ )
{
if (i == 3)
{
dt.Rows[i - 1].Delete();
dt.AcceptChanges();
}
}

Solution 1

use removeall method to delete record.

Example:
var authorsList = authorsList.Where(x => x.FirstName != "Bob").ToList();

authorsList.RemoveAll(x => x.FirstName == "Bob");

If i get two duplicate values i need to remove only a single value not all.

you are getting same values?

vangapally Naveen Kumar 1-Sep-14 9:35am

if you are getting same values use group by like
myList.GroupBy(x => x.id)
.Select(g => g.First());
or use distinct

like

myList.DistinctBy(x => x.id);
