Master页面：

 1 <%@ Master Language="C#" %>
 2 
 3 <script runat="server">
 4     protected void Page_Load(object sender, EventArgs e)
 5     {
 6         if (!Page.IsPostBack)
 7         {
 8             Label1.Text = System.Guid.NewGuid().ToString();
 9         }
10     }
11 </script>
12 
13 <html xmlns="http://www.w3.org/1999/xhtml" >
14 <head id="Head1" runat="server">
15     <title>My Company Master Page</title>
16     <asp:ContentPlaceHolder id="head" runat="server">
17     </asp:ContentPlaceHolder>
18 </head>
19 <body>
20     <form id="form1" runat="server">
21         <table cellpadding="3" border="1">
22             <tr bgcolor="silver">
23                 <td colspan="2">
24                     <h1>My Company Home Page</h1>
25                     <b>User's GUID:&nbsp;&nbsp;
26                         <asp:Label ID="Label1" Runat="server" /></b>
27                 </td>
28             </tr>
29             <tr>
30                 <td>
31                     <asp:ContentPlaceHolder ID="ContentPlaceHolder1" 
32                      Runat="server">
33                     </asp:ContentPlaceHolder>
34                 </td>
35                 <td>
36                     <asp:ContentPlaceHolder ID="ContentPlaceHolder2" 
37                      Runat="server">
38                     </asp:ContentPlaceHolder>
39                 </td>
40             </tr>
41             <tr>
42                 <td colspan="2">
43                     Copyright 2008 - My Company
44                 </td>
45             </tr>
46         </table>
47     </form>
48 </body>
49 </html>

在Master 页面设置 Label1.Text = System.Guid.NewGuid().ToString();

引用页面：

 1 <%@ Page Language="C#" MasterPageFile="~/Listing 05-08.master" Title="Untitled Page" %>
 2 
 3 <script runat="server">
 4 
 5     protected void Page_LoadComplete(object sender, EventArgs e)
 6     {
 7         Label1.Text = (Master.FindControl("Label1") as Label).Text;
 8         Master.FindControl("");
 9     }
10 
11     protected void Button1_Click(object sender, EventArgs e)
12     {
13         Label2.Text = "<b>Hello " + TextBox1.Text + "!</b>";
14     }
15 </script>
16 
17 <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
18 </asp:Content>
19 
20 <asp:Content ID="Content2" ContentPlaceHolderId="ContentPlaceHolder1" 
21  runat="server">
22     <b>Your GUID number from the master page is:<br />
23     <asp:Label ID="Label1" runat="server" /></b><p>
24     <b>Enter your name:</b><br />
25     <asp:Textbox ID="TextBox1" runat="server" />
26     <br />
27     <br />
28     <asp:Button ID="Button1" runat="server" Text="Submit"     OnClick="Button1_Click" /><br />
29     <br />
30     <asp:Label ID="Label2" runat="server" Font-Bold="True" />
31 </asp:Content>
