there are few mistakes, sample code:

C#

SqlDataReader reader = com.ExecuteReader();
if (reader.HasRows)
{
   while (reader.Read())
   {
 
      Username = reader["Username"] as string;
      UserId = reader["UserId"]  as string;
      return true;
   }
}

if you want one item, then replace your while loop with if
also check the msdn documentation which available with both c# and vb.net code samples
