Help on Imports in VB, please.

Question

Hello!-

As a new developer, I don't understand when and what Imports to use at the top of the code behind file.  I understand they allow acces to different namespaces and classes which allows different functionality (I believe), but how do I know when I should be adding them?

Would it be good practice to just add them on every page (or in the code behind of master page), something like this:

Imports System.Web.UI.WebControls
Imports System.Net.Mail
Imports System.IO
Imports System.Linq
Imports System.Web.UI
Imports System.Web.Security
Imports System.Collections.Generic
Imports System
Imports System.Web

and then I would always have it covered, or does that slow the system down?

the compiler will ignore namespaces not used. If you add a class and it's not in one of the listed namespaces at the top of your code file(Imports) then you must add it.

 

this add in works wonders for cleaning your code up and adding references when needed. tons more
