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);
