Overview of ASP. NET cookie operations

The most basic ASP. NET cookie operations:

 
 

  
  
HttpCookie cookie1 =NewHttpCookie ("User","Liuliang");
  
  
Cookie1 ["Age"] ="18";
  
  
Cookie1.Values. Add ("Sex","Male");
  
  
Cookie1.Expires = DateTime. Now. AddHours (1 );
  
  
Response. AppendCookie (cookie1 );
  
  
 
  
  
HttpCookie cookie =NewHttpCookie ("Luis");
  
  
Cookie. Values. Add ("Name","Dangdang");
  
  
Cookie ["Age"] ="23";
  
  
Cookie ["Sex"] ="Man";
  
  
Cookie. Expires = DateTime. Now. AddMinutes (0.5 );
  
  
Response. Cookies. Add (cookie );
 
 

Then read:

 
 

  
  
HttpCookie cookie = Request.Cookies["luis"];  
  
  
if (null == cookie)  
  
  
    return;  
  
  
Response.Write(cookie.Value);  
  
  
Response.Write("< br/>age" + cookie.Values.Count.ToString());  
  
  
Response.Write("< br/>age" + cookie["name"]);  
  
  
Response.Write("< br/>age" + cookie["age"]);  
  
  
Response.Write("< br/>sex" + cookie.Values["sex"]);  
  
  
Response.Write("< br/>sex" + cookie.Values[1]); 
 
 

Since cooike cannot be deleted directly on the server side, we only need to set it to expire.

 
 

  
  
// Delete the cookie 
  
  
HttpCookie cookie2 = Request. Cookies ["User"];
  
  
If(Null= Cookie2)
  
  
Return;
  
  
Cookie2.Expires = DateTime. Now. AddDays (-1 );
  
  
Response. AppendCookie (cookie2 );
 
 

Then we can:

Client to display cookies

The simplest code is:

 
 

  
  
var c=document.cookie.toString();  
  
  
alert(c);
