CodeBehind, CodeFile, Inline Code Snippet <%@ Import Namespace="System.Threading" %>

<%@ Import Namespace="System.Threading" %> 

Use inline when no public partial class MyCompanies : System.Web.UI.Page class definition in a CodeFile/CodeBehind

<%@ Page Language="C#" Title="EzPL8 - Relate by Plate: Investigate, Date, Communicate" uiculture="auto" EnableViewState="false"  EnableSessionState="False" MasterPageFile="~/Site.master"%>

<%@ Import Namespace="System.Threading" %>

<%@ Import Namespace="System.Globalization" %>

<%@ Import Namespace="System.Collections.Generic" %>

CodeBehind & CodeFile are a little cleaner with no <%, import, namespace, or quotes --just use using .

The difference between the two:

Behind leaves the source behind: it's compiled, with the DLL placed in the bin folder .

File is the source --for a partial class

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="MyCompanies.aspx.cs" Inherits="MyCompanies" EnableEventValidation="false" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

<script runat="server">
