在程序中使用Cookie集合(定义／新建／删除)及案例讲解

InsusBiz
using System;
using System.Web;
/// <summary>
/// Summary description for InsusBiz
/// </summary>
public class InsusBiz
{
private static HttpResponse Response
{
get
{
return HttpContext.Current.Response;
}
}
private static HttpRequest Request
{
get
{
return HttpContext.Current.Request;
}
}
//定义一个Cookie集合
private static HttpCookie InsusCookie
{
get
{
return Request.Cookies["InsusCookie"] as HttpCookie;
}
set
{
if (Request.Cookies["InsusCookie"] !=null)
{
Request.Cookies.Remove("InsusCookie");
}
Response.Cookies.Add(value);
}
}
//New Cookie集合
private static HttpCookie NewInsusCookie
{
get
{
HttpCookie httpCookie=new HttpCookie("InsusCookie");
return httpCookie;
}
}
//Remove Cookie集合
public static void RemoveInsusCookie()
{
if (InsusCookie==null)
Response.Cookies.Remove("InsusCookie");
else
Response.Cookies["InsusCookie"].Expires=DateTime.Now.AddDays(-1);
}
//创建一个Cookie，判断用户登录状态
public static bool LoginOk
{
get
{
return InsusCookie==null ? false : bool.Parse(InsusCookie.Values["LoginOk"]);
}
set
{
HttpCookie httpCookie=InsusCookie==null ? NewInsusCookie : InsusCookie;
httpCookie.Values["LoginOk"]=value.ToString();
InsusCookie=httpCookie;
}
}
//创建登录用户的帐号,整站使用
public static string MemberId
{
get
{
return InsusCookie==null ? string.Empty : InsusCookie.Values["MemberId"];
}
set
{
HttpCookie httpCookie=InsusCookie==null ? NewInsusCookie : InsusCookie;
httpCookie.Values["MemberId"]=value;
InsusCookie=httpCookie;
}
}
//如果还有整站使用的Cookie可以写在此，可以参考LoginOK或MemberId的写法。
}
