Question

I have the following simple LINQ to SQL statement:

string strUserID = Eval("whoInsert").ToString();

insLusHmoobDataContext userDataContext = new insLusHmoobDataContext();

var userName = from usr in userDataContext.Users
               where usr.UserId.Equals(strUserID)       
               select usr.UserName;

return userName.ToString();

Instead of showing me the UserName from the aspnet_Users table, it showed me the SQL select statement. Any idea?

Answer 1

var userName = (from usr in userDataContext.Users where usr.UserId.Equals(strUserID)     
select usr.UserName).SingleOrDefault();

That’s assuming there’s going to be a single user for that ID, else you could use FirstOrDefault().
