C#操作Cookie

一、存儲Cookie

HttpContext.Response.Cookies.Add(new HttpCookie(Cookie名稱, Cookie內容));

二、讀取Cookie

HttpContext.Request.Cookies[“Cookie名稱”];

三、刪除Cookie

通過新建一個立即過期的同內容cookie，將原有cookie進行覆蓋，從而完成刪除

HttpCookie newcookie;
newcookie = Request.Cookies["oldcookie"];
TimeSpan ts = new TimeSpan(0, 0, 0, 0);//時間跨度為0 
newcookie.Expires = DateTime.Now.Add(ts);//立即過期 
Response.Cookies.Add(newcookie);//寫入立即過期的cookie
