Valore della proprietà

HttpCookieCollection

Oggetto HttpCookieCollection che rappresenta le variabili cookie del client.

Esempio

Nell'esempio di codice seguente vengono scorrere tutti i cookie inviati dal client e vengono inviati il nome, la data di scadenza, il parametro di sicurezza e i valori di ogni cookie all'output HTTP.

int loop1, loop2;
HttpCookieCollection MyCookieColl;
HttpCookie MyCookie;

MyCookieColl = Request.Cookies;

// Capture all cookie names into a string array.
String[] arr1 = MyCookieColl.AllKeys;

// Grab individual cookie objects by cookie name.
for (loop1 = 0; loop1 < arr1.Length; loop1++)
{
   MyCookie = MyCookieColl[arr1[loop1]];
   Response.Write("Cookie: " + MyCookie.Name + "<br>");
   Response.Write ("Secure:" + MyCookie.Secure + "<br>");

   //Grab all values for single cookie into an object array.
   String[] arr2 = MyCookie.Values.AllKeys;

   //Loop through cookie Value collection and print all values.
   for (loop2 = 0; loop2 < arr2.Length; loop2++)
   {
      Response.Write("Value" + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");
   }
}

Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim MyCookieColl As HttpCookieCollection 
Dim MyCookie As HttpCookie

MyCookieColl = Request.Cookies
' Capture all cookie names into a string array.
arr1 = MyCookieColl.AllKeys
' Grab individual cookie objects by cookie name     
for loop1 = 0 To arr1.GetUpperBound(0)
   MyCookie = MyCookieColl(arr1(loop1))
   Response.Write("Cookie: " & MyCookie.Name & "<br>")
           Response.Write("Secure:" & MyCookie.Secure & "<br>")

   ' Grab all values for single cookie into an object array.
   arr2 = MyCookie.Values.AllKeys
   ' Loop through cookie value collection and print all values.
   for loop2 = 0 To arr2.GetUpperBound(0)
      Response.Write("Value " & CStr(loop2) + ": " & Server.HtmlEncode(arr2(loop2)) & "<br>")
   Next loop2
Next loop1
  

Commenti

ASP.NET include due raccolte intrinseche di cookie. La raccolta a cui si accede tramite la Cookies raccolta di HttpRequest contiene cookie trasmessi dal client al server nell'intestazione Cookie . La raccolta a cui si accede tramite la Cookies raccolta di HttpResponse contiene nuovi cookie creati nel server e trasmessi al client nell'intestazione Set-Cookie .
