Checking if a datatable is null

Question

The following code is what I\'ve been using to retrieve user information from a sql database.

            string userName = LoginUser.UserName;
            strin         


        

Answer 1

It seems to me using a DataTable and SqlDataAdapter is a little bit too heavy for the task.

You can just use a DataReader here:

        SqlCommand command = new SqlCommand(comm, conn);
        using (var reader = command.ExecuteQuery()) 
        {
            if (reader.Read())
            {
                //logic
                var userName = reader.GetString(0);
                var password = reader.GetString(1);
                // etc
            }
        }
