asp.net cookie的读写实例

asp.net操作cookie的例子，包括创建cookie、读取cookie、清空cookies，有需要的朋友可以参考下。

1、创建cookie

复制代码 代码如下:
HttpCookie cookie = new HttpCookie("AutoLogin");
cookie.Values.Add("name", user.UserName);
cookie.Values.Add("pass", user.Password);
cookie.Expires = DateTime.Now.AddDays(1);
Response.AppendCookie(cookie);


2、读取cookie
复制代码 代码如下:
HttpCookie cookies = Request.Cookies["AutoLogin"];
if (!IsPostBack)
{
if (cookies != null)
{
string name = cookies.Values["name"];
string pass = cookies.Values["pass"];
if (name != null && !name.Equals("") && pass != null && !pass.Equals(""))
{
UserManager userManager = new UserManager();
if (userManager.Login(name, pass, out user))
{
limits = userManager.GetLimitsById(user.ID);
Session["limits"] = limits;
Session["CurrentUser"] = user;
Response.Redirect("~/Display/Car/CarList.aspx");
}
}
}
}

3、清空cookies
复制代码 代码如下:
Response.Cookies["AutoLogin"].Expires = DateTime.Now.AddDays(-1);
