本文實例講述了C#自定義簡化cookie類。分享給大家供大家參考。具體分析如下：
這個C#類封裝了常用的cookie操作，包括讀取cookie、寫入cookie、設置cookie過期時間等等。
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> /// 獲取指定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> /// 添加一個Cookie（24小時過期） /// </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> /// 添加一個Cookie /// </summary> /// <param name="cookiename">cookie名</param> /// <param name="cookievalue">cookie值</param> /// <param name="expires">過期時間 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); } }}希望本文所述對大家的C#程序設計有所幫助。
