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(";")));

}

}
