本文实例讲述了C#自定义简化cookie类。分享给大家供大家参考。具体分析如下：

这个C#类封装了常用的cookie操作，包括读取cookie、写入cookie、设置cookie过期时间等等。

using System;using System.Web;namespace DotNet.Utilities{ public class CookieHelper { /// <summary> /// 清除指定Cookie /// </summary> /// <param name="cookiename">cookiename</param> public static void ClearCookie(string cookiename) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename]; if (cookie != null) { cookie.Expires = DateTime.Now.AddYears(-3); HttpContext.Current.Response.Cookies.Add(cookie); } } /// <summary> /// 获取指定Cookie值 /// </summary> /// <param name="cookiename">cookiename</param> /// <returns></returns> public static string GetCookieValue(string cookiename) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename]; string str = string.Empty; if (cookie != null) { str = cookie.Value; } return str; } /// <summary> /// 添加一个Cookie（24小时过期） /// </summary> /// <param name="cookiename"></param> /// <param name="cookievalue"></param> public static void SetCookie(string cookiename, string cookievalue) { SetCookie(cookiename, cookievalue, DateTime.Now.AddDays(1.0)); } /// <summary> /// 添加一个Cookie /// </summary> /// <param name="cookiename">cookie名</param> /// <param name="cookievalue">cookie值</param> /// <param name="expires">过期时间 DateTime</param> public static void SetCookie(string cookiename, string cookievalue,DateTime expires) { HttpCookie cookie = new HttpCookie(cookiename) { Value = cookievalue, Expires = expires }; HttpContext.Current.Response.Cookies.Add(cookie); } }}

希望本文所述对大家的C#程序设计有所帮助。
