ServiceDescription Class

Represents a complete, in-memory description of the service, including all the endpoints for the service and specifications for their respective addresses, bindings, contracts and behaviors.

Namespace:  System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class ServiceDescription

The information contained in the ServiceDescription is used by the Windows Communication Foundation (WCF) system to building the run-time components for the service.

Use this method when adding custom behaviors to extend ServiceHost. Programmatically, you must Add(T) the custom service behavior to the Behaviors prior to when you call the Open method on the ServiceHost object.

The GetService(Object) and GetService(Type) methods are available to reflect on behaviors using the Windows Communication Foundation (WCF) programming model when replacing ServiceHostBase with you own hosting mechanism.

Export metadata about a service endpoint by passing ServiceEndpoint as a parameter to ExportEndpoint(ServiceEndpoint). After calling this method, or one of the other export methods provided by WsdlExporter, use the GeneratedWsdlDocuments property to return the collection of ServiceDescription objects.

The following example illustrates various ways to instantiate a ServiceDescription object.

Uri baseAddress = new Uri("http://localhost:8001/Simple");
ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress);

    new WSHttpBinding(),

// Enable Mex
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;


// Use Default constructor
ServiceDescription sd = new ServiceDescription();

// Create ServiceDescription from a collection of service endpoints
List<ServiceEndpoint> endpoints = new List<ServiceEndpoint>();
ContractDescription conDescr = new ContractDescription("ICalculator");
EndpointAddress endpointAddress = new EndpointAddress("http://localhost:8001/Basic");
ServiceEndpoint ep = new ServiceEndpoint(conDescr, new BasicHttpBinding(), endpointAddress);
ServiceDescription sd2 = new ServiceDescription(endpoints);

//// Iterate through the list of behaviors in the ServiceDescription 
//ServiceDescription svcDesc = serviceHost.Description; 
//KeyedByTypeCollection<IServiceBehavior> sbCol = svcDesc.Behaviors; 
//foreach (IServiceBehavior behavior in sbCol) 
//    Console.WriteLine("Behavior: {0}", behavior.ToString());

ServiceDescription svcDesc = serviceHost.Description;
string configName = svcDesc.ConfigurationName;
Console.WriteLine("Configuration name: {0}", configName);

// Iterate through the endpoints contained in the ServiceDescription
ServiceEndpointCollection sec = svcDesc.Endpoints;
foreach (ServiceEndpoint se in sec)
    Console.WriteLine("\tAddress: {0}", se.Address.ToString());
    Console.WriteLine("\tBinding: {0}", se.Binding.ToString());
    Console.WriteLine("\tContract: {0}", se.Contract.ToString());
    KeyedByTypeCollection<IEndpointBehavior> behaviors = se.Behaviors;
    foreach (IEndpointBehavior behavior in behaviors)
        Console.WriteLine("Behavior: {0}", behavior.ToString());

string name = svcDesc.Name;
Console.WriteLine("Service Description name: {0}", name);

string namespc = svcDesc.Namespace;
Console.WriteLine("Service Description namespace: {0}", namespc);

Type serviceType = svcDesc.ServiceType;
Console.WriteLine("Service Type: {0}", serviceType.ToString());

// Instantiate a service description specifying a service object 
// Note: Endpoints collection and other properties will be null since  
// we have not specified them
CalculatorService svcObj = new CalculatorService();
ServiceDescription sd3 = ServiceDescription.GetService(svcObj);
String serviceName = sd3.Name;
Console.WriteLine("Service name: {0}", serviceName);
