MetadataResolver

Esempio

Nell'esempio di codice seguente viene illustrato l'utilizzo della classe MetadataResolver per restituire i metadati come raccolta di oggetti ServiceEndpoint che verranno quindi utilizzati per la connessione a un'istanza del servizio.

// Get the endpoints for such a service
ServiceEndpointCollection endpoints = MetadataResolver.Resolve(typeof(SampleServiceClient), metaAddress);
Console.WriteLine("Trying all available WS-Transfer metadata endpoints...");

foreach (ServiceEndpoint point in endpoints)
{
    if (point != null)
    {
        // Create a new wcfClient using retrieved endpoints.
        wcfClient = new SampleServiceClient(point.Binding, point.Address);
        Console.WriteLine(
          wcfClient.SampleMethod("Client used the "
          + point.Address.ToString()
          + " address.")
        );
        wcfClient.Close();
    }
}

Nell'esempio di codice seguente viene illustrato l'utilizzo di MetadataResolver per scaricare e restituire metadati come raccolta di oggetti ServiceEndpoint utilizzando una richiesta HTTP GET anziché WS-Transfer.

// Get the endpoints for such a service using Http/Get request
endpoints = MetadataResolver.Resolve(typeof(SampleServiceClient), httpGetMetaAddress.Uri, MetadataExchangeClientMode.HttpGet);
Client.WriteParameters(endpoints);
ISampleService serviceChannel;
Console.WriteLine(
  "\r\nTrying all endpoints from HTTP/Get and with direct service channels...");

foreach (ServiceEndpoint point in endpoints)
{
    if (point != null)
    {
        ChannelFactory<ISampleService> factory = new ChannelFactory<ISampleService>(point.Binding);
        factory.Endpoint.Address = point.Address;
        serviceChannel = factory.CreateChannel();
        Console.WriteLine("Client used the " + point.Address.ToString() + " address.");
        Console.WriteLine(
          serviceChannel.SampleMethod(
            "Client used the " + point.Address.ToString() + " address."
          )
        );
        factory.Close();
    }
}

Commenti

Utilizzare la classe MetadataResolver per importare rapidamente endpoint per un servizio da metadati. Questa classe scarica e converte metadati in oggetti ServiceEndpoint. Per scaricare metadati ed elaborare tali informazioni come System.ServiceModel.Description.MetadataSet, vedere System.ServiceModel.Description.MetadataExchangeClient.
