ServiceContractAttribute.Namespace Propriété

Définition

Espace de noms:

System.ServiceModel

Assembly:

System.ServiceModel.Primitives.dll

Assembly:

System.ServiceModel.dll

Obtient ou définit l'espace de noms de l'élément <portType> dans WSDL (Web Services Description Language).

public:
 property System::String ^ Namespace { System::String ^ get(); void set(System::String ^ value); };

public string Namespace { get; set; }

member this.Namespace : string with get, set

Public Property Namespace As String

Valeur de propriété

String

L'espace de noms WSDL de l'élément <portType>. La valeur par défaut est «http://tempuri.org ».

Exemples

L’exemple de code suivant montre comment utiliser les propriétés et Namespace les Name propriétés du ServiceContractAttribute fichier pour définir les valeurs correspondantes dans WSDL.

using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.Text;

namespace Microsoft.WCF.Documentation
{
  [ServiceContract(
    Name="HelloWorld",
    Namespace="http://Microsoft.WCF.Documentation"
  )]
  public interface ISampleService{
    [OperationContract]
    string SampleMethod(string msg);
  }

  class SampleService : ISampleService
  {
  #region ISampleService Members

  public string  SampleMethod(string msg)
  {
      return "The service greets you: " + msg;
  }

  #endregion
  }
}

Imports System.Collections.Generic
Imports System.ServiceModel
Imports System.Text

Namespace Microsoft.WCF.Documentation
  <ServiceContract(Name:="HelloWorld", Namespace:="http://Microsoft.WCF.Documentation")> _
  Public Interface ISampleService
    <OperationContract> _
    Function SampleMethod(ByVal msg As String) As String
  End Interface

  Friend Class SampleService
      Implements ISampleService
  #Region "ISampleService Members"

  Public Function SampleMethod(ByVal msg As String) As String Implements ISampleService.SampleMethod
       Return "The service greets you: " & msg
  End Function

  #End Region
  End Class
End Namespace

L’exemple de code suivant montre un client Windows Communication Foundation (WCF) pour le service précédent qui a importé WSDL à l’aide de l’outil utilitaire de métadonnées ServiceModel (Svcutil.exe). Ce client utilise un HelloWorldClient client plutôt qu’un SampleServiceClient client (comme c’est le cas avec l’exemple dans la section Exemple de ServiceContractAttribute).

using System;
using System.ServiceModel;
using System.ServiceModel.Channels;

public class Client
{
  public static void Main()
  {
    // Picks up configuration from the config file.
    HelloWorldClient wcfClient = new HelloWorldClient();
    try
    {
      // Making calls.
      Console.WriteLine("Enter the greeting to send: ");
      string greeting = Console.ReadLine();
      Console.WriteLine("The service responded: " + wcfClient.SampleMethod(greeting));

      // Done with service.
      wcfClient.Close();
      Console.WriteLine("Done!");
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine("The service operation timed out. " + timeProblem.Message);
      wcfClient.Abort();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine("There was a communication problem. " + commProblem.Message);
      wcfClient.Abort();
    }
    finally
    {
      Console.WriteLine("Press ENTER to exit:");
      Console.ReadLine();
    }
  }
}

Imports System.ServiceModel
Imports System.ServiceModel.Channels

Public Class Client
  Public Shared Sub Main()
    ' Picks up configuration from the config file.
    Dim wcfClient As New HelloWorldClient()
    Try
      ' Making calls.
      Console.WriteLine("Enter the greeting to send: ")
            Dim greeting = Console.ReadLine()
      Console.WriteLine("The service responded: " & wcfClient.SampleMethod(greeting))

      ' Done with service. 
      wcfClient.Close()
      Console.WriteLine("Done!")
    Catch timeProblem As TimeoutException
      Console.WriteLine("The service operation timed out. " & timeProblem.Message)
      wcfClient.Abort()
    Catch commProblem As CommunicationException
      Console.WriteLine("There was a communication problem. " & commProblem.Message)
      wcfClient.Abort()
    Finally
      Console.WriteLine("Press ENTER to exit:")
      Console.ReadLine()
    End Try
  End Sub
