C#读写Cookie

用C#如何创建、读取cookie：

一、创建cookie，并写入数据：

   //创建、写入Cookie

    HttpCookie cookie = Request.Cookies["MWS_User"];

    if (cookie == null)

    {

          cookie = new HttpCookie("MWS_User");

    }

    cookie.Values.Set("UserID", strUserID);

    Response.SetCookie(cookie);

 

二、读取cookie：

HttpCookie cookie = Request.Cookies["MWS_User"];

if (cookie != null && cookie["UserID"].ToString() != "")

{

      Response.Write("cookie=" + cookie["UserID"].ToString());

}

三、删除Cookie

Response.Cookies["Cookiename"].Expires = DateTime.Now.AddDays(-1);
