1 <%@ Page Language="C#" %> 2 3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 4 5 <script runat="server"> 6 void Page_Load() 7 { 8 if (Request.Cookies["message"] != null) 9 { 10 lblCookieValue.Text = Request.Cookies["message"].Value; 11 } 12 } 13 </script> 14 15 <html xmlns="http://www.w3.org/1999/xhtml"> 16 <head runat="server"> 17 <title>Get Cookie</title> 18 </head> 19 <body> 20 <form id="form1" runat="server"> 21 <div> 22 23 The value of the message cookie is: 24 <asp:Label 25 id="lblCookieValue" 26 Runat = "server" /> 27 </div> 28 </form> 29 </body> 30 </html>
如果想读出Request.Cookies集合中所有的cookie值,可以这样。
<%@ Page Language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> void Page_Load() { ArrayList colCookies = new ArrayList(); for (int i = 0; i < Request.Cookies.Count; i++) { colCookies.Add(Request.Cookies[i]); } grdCookies.DataSource = colCookies; grdCookies.DataBind(); } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Get All Cookies</title> </head> <body> <form id="form1" runat="server"> <div> <asp:GridView id="grdCookies" Runat="server" /> </div> </form> </body> </html>
