  1.   


    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="InformationManage.aspx.cs"
        Inherits="Information_InfomationManage" MasterPageFile="~/MasterPage.master"
        Title="信息管理" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
    </asp:Content>
    这是其它页面的结构。
      

  2.   

    <%@ Page Language="C#" MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" Title="无标题页" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    </asp:Content>
     这是其他页面结构。选择模板页来的。
