`from..where` or `FirstOrDefault` in LINQ

Question

Traditionally, when I\'ve tried to get data for a user from a database, and I\'ve used the following method (to some degree):

DbUsers curUser = context.DbUsers.F         


        

Answer 1

The second is better. You only get the needed data from database so the network traffic is lighter.

You can have the same result with extension methods:

var user = context.DbUsers
                  .Where(x => x.u_LoginName == id)
                  .Select(x => new {...})
                  .FirstOrDefault();
