asp.net
From quickstart:
Simplified Code Behind Model New in 2.0
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.
這對開發來說確實是一個改進,CodeBehind中去掉server control的聲明會使代碼"清爽"很多，看起來舒服多了。請看樣本:

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

</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);
}
}
