24,574
Solution 1
Give this a try
public static List<string> GetAttachmentKeyList()
{
DataClassesDataContext dc = new DataClassesDataContext();
List<string> list = ( from a in dc.Attachments
select a.Att_Key.ToString() ).ToList();
return list;
}
Solution 2
try this,
public static List<string> GetAttachmentKeyList()
{
DataClassesDataContext dc = new DataClassesDataContext();
return dc.Attachments.Select(a=>a.Att_Key).ToList();
}
Solution 3
I guess it would something like below.
List<string> list = (from a in dc.Attachments
select a.Att_Key.ToString()).ToList<string>();
Hope this helps!!

I am trying to do something like this...
public static List<string> GetAttachmentKeyList() { DataClassesDataContext dc = new DataClassesDataContext(); List<string> list = from a in dc.Attachments select a.Att_Key.ToString().ToList(); return list; }
Visual Studio is saying...
Cannot implicitly convert type 'System.Linq.IQueryable>' to 'System.Collections.Generic.List'. An explicit conversion exists (are you missing a cast?)
What is the proper syntax???
