需要注意HttpOnly,Path等属性。完整的测试代码：

ASPX 代码


<%@ 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">



  protected void Page_Load(object sender, EventArgs e)

  {

    if (!Page.IsPostBack)

    {

      HttpCookie Cookie = new HttpCookie("user");

      Cookie.Values.Add("name", "mxh");

      Cookie.Values.Add("id", "net_lover");

      Cookie.Expires = DateTime.Now.AddDays(1);

      Cookie.HttpOnly = false;

      Cookie.Path = "/";

      Response.Cookies.Add(Cookie);

    }

  }



  protected void Button1_Click(object sender, EventArgs e)

  {

    if (Request.Cookies["user"] == null)

    {

      Response.Write("已经删除");

    }

    else

    {

      Response.Write("Cookie值： " + Request.Cookies["user"]["name"]);

    }



  }

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

  <title>dotnet.aspx.cc Cookie 测试</title>

  <script type="text/javascript">

    function deleteCookie() {

      var expires = new Date();

      expires.setUTCFullYear(expires.getUTCFullYear() - 1);

      document.cookie = "user=name=&id=; expires=" + expires.toUTCString() + "; path=/";

    }

  </script>

</head>

<body>

  <form id="form1" runat="server">

  <input type="button" value="删除" onclick="deleteCookie()" />

  <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="查看Cookie" />

  </form>

</body>

</html>
