一个ASP.Net(C#)访问Cookie的封装

不多说，直接上代码

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;

namespace csTools {
	public class Cookie {
		/// <summary>
		/// 设置Cookie的值，关闭Session后释放
		/// </summary>
		/// <param name="name">名称</param>
		/// <param name="value">Cookie值</param>
		/// <param name="response">HttpResponse</param>
		public static void Set(string name, string value, HttpResponse response) {
			HttpCookie cookie = new HttpCookie(name);
			cookie.Values.Add(name, value);
			response.AppendCookie(cookie);
		}



		/// <summary>
		/// 设置Cookie的值，包含过期时间
		/// </summary>
		/// <param name="name">名称</param>
		/// <param name="value">Cookie值</param>
		/// <param name="expiredays">过期时间</param>
		/// <param name="response">HttpResponse</param>
		public static void Set(string name, string value, DateTime expiredays, HttpResponse response) {
			HttpCookie cookie = new HttpCookie(name);
			cookie.Expires = expiredays;
			cookie.Values.Add(name, value);
			response.AppendCookie(cookie);
		}



		/// <summary>
		/// 获取Cookie值
		/// </summary>
		/// <param name="name">名称</param>
		/// <param name="request">HttpRequest</param>
		/// <returns>Cookie的值</returns>
		public static string Get(string name, HttpRequest request) {
			if (request.Cookies[name] != null) {
				return request.Cookies[name].Values[name];
			} else {
				return null;
			}
		}



		/// <summary>
		/// 删除Cookie
		/// </summary>
		/// <param name="name">名称</param>
		/// <param name="response">HttpResponse</param>
		/// <param name="request">HttpRequest</param>
		public static void Delete(string name, HttpResponse response, HttpRequest request) {
			HttpCookie cookie = request.Cookies[name];
			if (cookie != null) {
				cookie.Expires = DateTime.Now.AddYears(-10);
				response.AppendCookie(cookie);
			}
		}



		/// <summary>
		/// 修改Cookie的值
		/// </summary>
		/// <param name="name">名称</param>
		/// <param name="value">Cookie值</param>
		/// <param name="response">HttpResponse</param>
		/// <param name="request">HttpRequest</param>
		public static void Modify(string name, string value, HttpResponse response, HttpRequest request) {
			HttpCookie cookie = request.Cookies[name];
			if (cookie != null) {
				cookie.Values[name] = value;
			}
			response.AppendCookie(cookie);
		}
	}
}

对常用cookie功能进行封装，方便服务器访问cookie。注释
