Exemples

L’exemple suivant montre comment utiliser WebPermissionAttribute pour spécifier une chaîne autorisée Accept .

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

   static void CheckAcceptPermission( String^ uriToCheck )
   {
      WebPermission^ permissionToCheck = gcnew WebPermission;
      permissionToCheck->AddPermission( NetworkAccess::Accept, uriToCheck );
      permissionToCheck->Demand();
   }

   static void demoDenySite()
   {
      // Pass the security check when accessing allowed resources.
      CheckAcceptPermission( "http://www.contoso.com/" );
      Console::WriteLine( "Public page has passed Accept permission check" );

      try
      {
         // Throw a SecurityException when trying to access not allowed resources.
         CheckAcceptPermission( "http://www.contoso.com/Private.htm" );
         Console::WriteLine( "This line will not be printed" );
      }
      catch ( SecurityException^ e ) 
      {
         Console::WriteLine( "Exception trying to access private resource: {0}", e->Message );
      }
   }

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

public static void CheckAcceptPermission(string uriToCheck) 
{
    WebPermission permissionToCheck = new WebPermission();
    permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck);
    permissionToCheck.Demand();
}

public static void demoDenySite() 
{
    //Pass the security check when accessing allowed resources.
    CheckAcceptPermission("http://www.contoso.com/");
    Console.WriteLine("Public page has passed Accept permission check");

    try 
    {
        //Throw a SecurityException when trying to access not allowed resources.
        CheckAcceptPermission("http://www.contoso.com/Private.htm");
        Console.WriteLine("This line will not be printed");
    }
    catch (SecurityException e) 
    {
        Console.WriteLine("Exception trying to access private resource:" + e.Message);
    }
 }

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

<WebPermission(SecurityAction.Deny, Accept := "http://www.contoso.com/Private.htm")>  _
   Public Shared Sub CheckAcceptPermission(uriToCheck As String)
   Dim permissionToCheck As New WebPermission()
   permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck)
   permissionToCheck.Demand()
End Sub


Public Shared Sub demoDenySite()
   ' Pass the security check when accessing allowed resources.
   CheckAcceptPermission("http://www.contoso.com/Public.htm")
   Console.WriteLine("Public page has passed Accept permission check")
   Try
      'Throw a SecurityException when trying to access not allowed resources.
      CheckAcceptPermission("http://www.contoso.com/Private.htm")
      Console.WriteLine("This line will not be printed")
   Catch e As SecurityException
      Console.WriteLine(("Exception trying to access private resource:" + e.Message))
   End Try
End Sub

Remarques

Lors de l’application WebPermissionAttribute à votre classe, cette propriété spécifie la chaîne d’URI qui sera acceptée pour une utilisation dans votre classe. Cette autorisation est appliquée lorsque le système de sécurité appelle CreatePermission. Cette propriété est en écriture unique.
