C# javascript 读写Cookie

第一：写Cookies Response.Cookies["UserName"].Value="Guest"; Response.Cookies["UserName"].Expires=DateTime.Now.AddDays(1); 第二：添加Cookies HttpCookie userName_zhengshu_Cookie = new HttpCookie("uname"); userName_zhengshu_Cookie.Value = "陈

第一：写Cookies

Response.Cookies["UserName"].Value="Guest";
Response.Cookies["UserName"].Expires=DateTime.Now.AddDays(1);

第二：添加Cookies

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);

//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(";")));
　　}
