Asp.net 操作cookie大全

实例代码:
  
下面是写cookie

 

HttpCookie cookie = new HttpCookie("Info");//定义cookie对象以及名为Info的项 
    DateTime dt = DateTime.Now;//定义时间对象 
    TimeSpan ts=new TimeSpan(1,0,0,0);//cookie有效作用时间,具体查msdn 
    cookie.Expires = dt.Add(ts);//添加作用时间 
    cookie.Values.Add("user","cxbkkk");//增加属性 
    cookie.Values.Add("userid","1203"); 
    Response.AppendCookie(cookie);//确定写入cookie中 

读取cookie

 

if(Request.Cookies["Info"]!=null) 
    { 
    string temp=Convert.ToString(Request.Cookies["Info"].Values["user"])+" "+Convert.ToString(Request.Cookies["Info"].Values["userid"]); 
    //读全部就用Request.Cookies["Info"].Value
    if(temp=="") 
    { 
    Response.Write(""); 
    } 
    else 
    Response.Write(temp); 
    } 
    else 
   { 
   Response.Write("error"); 
   } 

修改cookie

 

Response.Cookies["Info"]["user"] = "2"; 
   Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1);

 

删除cookie下的属性

 

HttpCookie acookie=Request.Cookies["Info"]; 
   acookie.Values.Remove("userid"); 
   acookie.Expires = DateTime.Now.AddDays(1); 
   Response.Cookies.Add(acookie); 

删除所有cookie,就是设置过期时间为现在就行了

 

 int limit=Request.Cookies.Count - 1; 
   for(int i=0;i<limit;i++) 
   { 
   acookie = Request.Cookies(i) 
   acookie.Expires = DateTime.Now.AddDays(-1) 
   Response.Cookies.Add(acookie) 
   }
