ASP中Cookie的创建使用和删除

最近发现好多东西都没记录下来，有点忘记了，借此记录一下。

创建Cookie

 

1 HttpCookie myCookie = new HttpCookie("UserSettings");
2 myCookie["Font"] = "Arial";
3 myCookie["Color"] = "Blue";
4 myCookie.Expires = DateTime.Now.AddDays(1d);
5 Response.Cookies.Add(myCookie);
  

 

效果：

 

设置cookie的路径，应该是用来限制myCookie的访问范围。

 

1    myCookie.Path = "test";

 

 

效果：

使用Cookie：

 

1 if (Request.Cookies["UserSettings"] != null)
2 {
3     string userSettings;
4     if (Request.Cookies["UserSettings"]["Font"] != null)
5     { userSettings = Request.Cookies["UserSettings"]["Font"]; }
6 }
7  

 

 

删除Cookie：

 

1 
2  if (Request.Cookies["UserSettings"] != null)
3 {
4     HttpCookie myCookie = new HttpCookie("UserSettings");
5     myCookie.Expires = DateTime.Now.AddDays(-1d);
6     Response.Cookies.Add(myCookie);
7 }

 

 

 

设置过期即可删除Cookie
