Contoh

Contoh berikut mengilustrasikan berbagai cara untuk membuat instans ServiceDescription objek.

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

serviceHost.AddServiceEndpoint(
    typeof(ICalculator),
    new WSHttpBinding(),
    "CalculatorServiceObject");

// Enable Mex
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
serviceHost.Description.Behaviors.Add(smb);

serviceHost.Open();

// 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);
endpoints.Add(ep);
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());
}

// svcDesc is a 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("Endpoint:");
    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);

Dim baseAddress As New Uri("http://localhost:8001/Simple")

' Iterate through the list of behaviors in the ServiceDescription
Dim svcDesc As ServiceDescription = serviceHost.Description
Dim sbCol As KeyedByTypeCollection(Of IServiceBehavior) = svcDesc.Behaviors
For Each behavior As IServiceBehavior In sbCol
    Console.WriteLine("Behavior: {0}", CType(behavior, Object).ToString())
Next behavior

    Console.WriteLine("Endpoint:")
    Console.WriteLine(Constants.vbTab & "Address: {0}", se.Address.ToString())
    Console.WriteLine(Constants.vbTab & "Binding: {0}", se.Binding.ToString())
    Console.WriteLine(Constants.vbTab & "Contract: {0}", se.Contract.ToString())
    Dim behaviors As KeyedByTypeCollection(Of IEndpointBehavior) = se.Behaviors
    For Each behavior As IEndpointBehavior In behaviors
        Console.WriteLine("Behavior: {0}", CType(behavior, Object).ToString())
    Next behavior
Next se

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

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

Dim serviceType As Type = 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

Dim svcObj As New CalculatorService()
Dim sd3 As ServiceDescription = ServiceDescription.GetService(svcObj)

Console.WriteLine("Service name: {0}", serviceName)

Keterangan

Informasi yang terkandung dalam ServiceDescription digunakan oleh sistem Windows Communication Foundation (WCF) untuk membangun komponen run-time untuk layanan.

Gunakan metode ini saat menambahkan perilaku kustom untuk memperluas ServiceHost. Secara terprogram, Anda harus Add(T) perilaku layanan kustom sebelum Behaviors saat Anda memanggil Open metode pada ServiceHost objek.

Metode GetService(Object) dan GetService(Type) tersedia untuk merefleksikan perilaku menggunakan model pemrograman Windows Communication Foundation (WCF) saat mengganti ServiceHostBase dengan mekanisme hosting Anda sendiri.

Ekspor metadata tentang titik akhir layanan dengan meneruskan ServiceEndpoint sebagai parameter ke ExportEndpoint(ServiceEndpoint). Setelah memanggil metode ini, atau salah satu metode ekspor lain yang disediakan oleh WsdlExporter, gunakan GeneratedWsdlDocuments properti untuk mengembalikan kumpulan ServiceDescription objek.
