        List<CandidateInfo> candidateList = CandidatesID.Select(c => CandidateController.Instance[Convert.ToInt32(c.Trim())]).Where(item => item != null).ToList(); // Candidate List

Your question makes no sense, a List does not have columns, it just contains a group of items.

Hi Richard,
yes, u r rit, but i have candidiateInfo, which contains candidate id, name, cell no, age...etc..

What does that mean? Please edit your question and explain (using proper words not txtspk) what your problem is. Saying that you want to add a column to a List makes no sense.

Judging by your comments, you would need to add the GroupName to your CanidateInfo class. Nothing else you have said makes any sense.

So your you just need to add the missing properties to your class.

Your class should look something like the follow, not sure what that code snippet you posted is from.

C#

public class CandidateInfo
{
   public int CandidateId {get;set;}
   public string Name {get;set;}
   public string CellNo {get;set;}
   public int Age {get;set;}
   //Add more properties here as you need them. Ex:
   public string GroupName {Get;set;}
}

Then you'll be able to access/assign values to any properties you add later on while using the CandidateInfo class. Ex:

C#

var candidates = new List<CandidateInfo>();
var c1 = new CandidateInfo();
c1.Name = "Matt";
c1.GroupName = "Group 1";

var c2 = new CandidateInfo();
c1.Name = "Mark"
c1.GroupName = "Group 2";

candidates.Add(c1);
candidates.Add(c2);
