ASP.NET 2.0 new features [Simplified Code Behind Model]

ASP.NET 2.0 new features [Simplified Code Behind Model] From quickstart:

Simplified Code Behind Model ASP.NET 2.0 introduces an improved runtime for code-behind pages that simplifies the connections between the page and code. In this new code-behind model, the page is declared as a partial class, which enables both the page and code files to be compiled into a single class at runtime. The page code refers to the code-behind file in the CodeFile attribute of the <%@ Page %> directive, specifying the class name in the Inherits attribute. Note that members of the code behind class must be either public or protected (they cannot be private).

C# CodeBehind Code Separation

The advantage of the simplified code-behind model over previous versions is that you do not need to maintain separate declarations of server control variables in the code-behind class. Using partial classes (new in 2.0) allows the server control IDs of the ASPX page to be accessed directly in the code-behind file. This greatly simplifies the maintenance of code-behind pages.

这对开发来说确实是一个改进,CodeBehind中去掉server control的声明会使代码'清爽'很多，看起来舒服多了。请看示例:

这对开发来说确实是一个改进,CodeBehind中去掉server control的声明会使代码'清爽'很多，看起来舒服多了。请看示例:页面中我们放置一个textbox:Test.aspx

<%@ page language='C#' CodeFile='Test.aspx.cs' Inherits='Test_aspx' %>

<html>

<head>

</head>

<body>

<asp:TextBox ID='TextBox1' Runat='server'/>

<asp:Button ID='Button1' Text='Click Me' OnClick='Button1_Click' Runat='server'/>

br />

</form>

</body>

</html>Test.aspx.csusing System;

public partial class Test_aspx: System.Web.UI.Page

{

protected void Button1_Click(object sender, EventArgs e)

{

Response.Write ( 'Hi,you have entered the word: ' + TextBox1.Text);

}
