最近开始学 ASP.NET，然后发现 Cookie 的设置不像 PHP 简单粗暴(PHP Cookie用法)，于是就造个轮子省事，注释很详细，这里就不再赘言。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web;r
namespace BuildWheel
{
/// <summary>
/// Cookie辅助类
/// </summary>
public class CookieHelper
{
/// <summary>
/// 设置、删除、修改cookie
/// </summary>
/// <param name="cookieName">cookie名称</param>
/// <param name="cookieValue">cookie值</param>
/// <param name="expires">过期时间</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);
}
/// <summary>
/// 删除指定cookie
/// </summary>
/// <param name="cookieName">cookie名称</param>
public static void DeleteCookie(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>
/// 清除所有cookie
/// </summary>
public static void ClearCookies()
{
HttpContext.Current.Request.Cookies.AllKeys.ToList().ForEach((e) =>
{
HttpCookie cookie = HttpContext.Current.Response.Cookies[e];
cookie.Expires = DateTime.Now.AddYears(-3);
HttpContext.Current.Response.Cookies.Add(cookie);
});
}
/// <summary>
/// 获取cookie值
/// </summary>
/// <param name="cookieName">cookie名称</param>
/// <returns></returns>
public static string GetCookieValue(string cookieName)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieName];
string cookieValue = string.Empty;
if (cookie != null)
{
cookieValue = cookie.Value;
}
return cookieValue;
}
}
}
有错误欢迎指出~
