MVC中Cookie的用法(一)

1创建Cookie

1.1直接创建

Response.Cookies["Account"].Value = "test1";

Response.Cookies["Account "].Expires = DateTime.Now. AddHour (8);



1.2
HttpCookie创建

HttpCookie
hck = new HttpCookie("User");

hck.Value
= DateTime.Now.ToString();

hck.Expires
= DateTime.Now. AddHour (8);

Response.Cookies.Add(hck);

2读取Cookie

string tmp1 = "";

if (Request.Cookies["Account"]
!= null)

{

tmp1 = Request.Cookies["Account"].Value.ToString();

}

else

{

tmp1 = "Cookie不存在";

}

3修改Cookie

if
(Request.Cookies["Account"] == null)

{

Response.Cookies["Account"].Value = "test2";

Response.Cookies["Account "].Expires = DateTime.Now.AddHour(8);

}

else

{

Response.Cookies["Account"].Value = "test3";

Response.Cookies["Account "].Expires = DateTime.Now. AddHour (8);

}

4删除Cookie

if (Request.Cookies["Account "] != null)

{

Response.Cookies["Account "].Expires = DateTime.Now. AddYears (-3);

}
