Örnekler

Aşağıdaki örnekte bir yönteme nasıl uygulanacağı WebPermissionAttribute gösterilmektedir.

public:
   // Deny access to a specific resource by setting the ConnectPattern property.
   [method:WebPermission(SecurityAction::Deny,ConnectPattern="http://www.contoso.com/")]

   void Connect()
   {
      // Create a Connection.
      HttpWebRequest^ myWebRequest = (HttpWebRequest^)(WebRequest::Create( "http://www.contoso.com" ));
      Console::WriteLine( "This line should never be printed" );
   }

    // Deny access to a specific resource by setting the ConnectPattern property. 
   [WebPermission(SecurityAction.Deny, ConnectPattern=@"http://www\.contoso\.com/")]

public void Connect() 
     {
        // Create a Connection.  
        HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create("http://www.contoso.com");
        Console.WriteLine("This line should never be printed");
     }

' Deny access to a specific resource by setting the ConnectPattern property.

Açıklamalar

WebPermissionAttribute , sınıfınızın hangi URI dizelerini ve normal ifade dizelerini kullanabileceğini bildirimli olarak belirtmenizi sağlar.

içinde WebPermissionAttribute belirtilen güvenlik bilgileri, uygulanan sınıf WebPermissionAttribute olan öznitelik hedefinin meta verilerinde depolanır. Sistem bu bilgilere çalışma zamanında erişir. System.Security.Permissions.SecurityAction Oluşturucuya geçirilen izin verilebilen WebPermissionAttribute hedefleri belirler. Sistem, öznitelik hedefinin CreatePermission güvenlik bilgilerini meta verilerde depolanan serileştirilebilir bir forma dönüştürmek için yöntemi tarafından döndürülen öğesini kullanırWebPermission.
