Question

How can I select a list of column values from a result set (as distinct) and put into a list?

class T {int id; string name;}

— Controller…

var query = @"exec someStoredProc";
IEnumerable<T> bb =
 db2.Database.SqlQuery<T>(query);    

// Something like???:
List<string> Names = bb.SelectDistinct("name");  // returns distinct list of names from result set

Answer 1

Since you just need the distinct list of names, you can project to the name property and the just use Distinct() :

List<string> Names = bb.Select( x=> x.name)
                       .Distinct()
                       .ToList();

This requires that you make the name property public, also I would rethink your class name T, how about CustomerName (or whatever else is expressive enough so you know what it means) ?

public class CustomerName 
{
  public int id{get;set;}
  public string name {get;set;}
}
