MetadataResolver Class
Assembly: System.ServiceModel (in system.servicemodel.dll)
Use the MetadataResolver class to quickly import endpoints for a service from metadata. This class downloads and converts metadata into ServiceEndpoint objects. To download metadata and process that information as a System.ServiceModel.Description.MetadataSet, see System.ServiceModel.Description.MetadataExchangeClient.
The following code example shows the use of the MetadataResolver class to return metadata as a collection of ServiceEndpoint objects that are then used to connect to a service instance.
// 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(); } }
The following code example shows the use of the MetadataResolver to download and return metadata as a collection of ServiceEndpoint objects using an HTTP GET request rather than 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(); } }
