<asp:Button ID="Button1" runat="server" onclick="Button1_Click"

Text="写Cookie" />

<asp:Button ID="Button2" runat="server" onclick="Button2_Click"

</body>

后台：

protected void Button1_Click(object sender, EventArgs e)

//每一个就是一个cookie，cookie1

HttpCookie WriteCookiename = new HttpCookie("cookiename");

WriteCookiename.Value = "小红";

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

Response.Cookies.Add(WriteCookiename);

//cookie2 其cookie的内容不能超过20个

HttpCookie WriteCookieage = new HttpCookie("cookieage");

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

Response.Cookies.Add(WriteCookieage);

protected void Button2_Click(object sender, EventArgs e)

{

//下面的删除cookie的值，只能删除cookie1的内容，不删除cookie2的内容，因为它只删除了cookiename的内容，没有删除cookieage的内容

HttpCookie DeleteCookie = new HttpCookie("cookiename");

DeleteCookie.Expires = DateTime.Now.AddDays(-2);
