大家都知道，网站一般都会用Session保存用户的ID,但是容易过期，经常丢失，然而用Cookies就比较好了，下面就是我的读写Cookies的代码。
/// <summary>
/// 写Cookies /// </summary> /// <param name="response"></param> /// <param name="request"></param> /// <param name="server"></param> /// <param name="IndexValue"></param> /// <param name="TextValue"></param>
/// <param name="ExpriesHour">设置的过期时间</param>
public void WriteCookies(HttpResponse response,HttpRequest request,HttpServerUtility server,string IndexValue,string TextValue,int ExpriesHour) {
response.Cookies[IndexValue].Value = TextValue; response.Cookies[IndexValue].Expires = System.DateTime.Now.AddHours(ExpriesHour); } /// <summary> /// 读Cookies /// </summary> /// <param name="response"></param> /// <param name="request"></param> /// <param name="server"></param> /// <param name="IndexValue"></param> /// <returns></returns> public string ReadCookies(HttpResponse response, HttpRequest request, HttpServerUtility server, string IndexValue) { if (request.Cookies[IndexValue] != null) return request.Cookies[IndexValue].Value.ToString(); return ""; } /// <summary> /// 删除Cookies，立即过期 /// </summary> /// <param name="response"></param> /// <param name="request"></param> /// <param name="server"></param> /// <param name="IndexValue"></param> public void DeleteCookies(HttpResponse response, HttpRequest request, HttpServerUtility server, string IndexValue) { if (request.Cookies[IndexValue] != null)
{ 
HttpCookie cookies=request .Cookies[IndexValue]; cookies .Expires=System.DateTime.Now.AddHours(-1); response.Cookies.Add(cookies);
} }
