C# javascript 读写Cookie的方法

第一：写cookies
复制代码 代码如下:
Response.cookies["UserName"].Value="Guest";
Response.cookies["UserName"].Expires=DateTime.Now.AddDays(1);

第二：添加cookies
复制代码 代码如下:
 Httpcookie userName_zhengshu_cookie = new Httpcookie("uname");
        userName_zhengshu_cookie.Value = "陈xx";

        Httpcookie userLession_zhengshur_cookie = new Httpcookie("lcode");
        userLession_zhengshur_cookie.Value = "chen jian ping";

        userName_zhengshu_cookie.Path = "/";
        userLession_zhengshur_cookie.Path = "/";

//限定有效期
        userLession_zhengshur_cookie.Expires = DateTime.Now.AddDays(1);
        userName_zhengshu_cookie.Expires = DateTime.Now.AddDays(1);

        Response.cookies.Add(userLession_zhengshur_cookie);
        Response.cookies.Add(userName_zhengshu_cookie);

//cookies添加
 Response.Appendcookie(user_cookies);

//取值
Response.Write(Request.cookies["uname"].Value);


复制代码 代码如下:
//javascript写读cookie
function Set_cookie()
{
    var setValue="陈xx";
    var exdate=new Date();
    exdate.setDate(exdate.getDate()+365);
    document.cookie="userLession"+ "=" +setValue+";expires="+exdate.toGMTString()+";path=/";
    alert("已经写入cookie");
}

 function Get(){　     
   　　var cookieString=new String(document.cookie)     
   　　var cookieHeader = "userLession="     
   　　var beginPosition = cookieString.indexOf(cookieHeader)     
   　　if(beginPosition != -1)
   　　{     
   　　　　alert(cookieString.substring(cookieHeader.length,cookieString.indexOf(";")));  
   　　}     
   }
