ASP.Net指令是用于指定可选设置的指令，例如注册自定义控件和页面语言.这些设置描述了.Net框架如何处理Web表单(.aspx)或用户控件(.ascx)页面.

声明指令的语法为:

ASP.Net directives are instructions to specify optional settings, such as registering a custom control and page language. These settings describe how the web forms (.aspx) or user controls (.ascx) pages are processed by the .Net framework.

The syntax for declaring a directive is:

<![CDATA[<%@  directive_name attribute=value  [attribute=value]  %>]]>

通用页面指令之一是母版页.主指令将页面文件指定为主页面. Herez示例代码:

One of the common page directive is masterpage. Master directive specifies a page file as being the mater page. Herez the sample code:

<%@ MasterPage Language="C#"  AutoEventWireup="true"

    CodeFile="SiteMater.master.cs" Inherits="SiteMaster"  %>
