Örnekler

Aşağıdaki kod örneği bir BindingElementüzerinde uygulamasını IPolicyExportExtension gösterir. Bu örnekte, WSDL dosyasına bağlama düzeyinde özel bir bağlama öğesi eklenmiştir.

#region IPolicyExporter Members
public void ExportPolicy(MetadataExporter exporter, PolicyConversionContext policyContext)
{
  if (exporter == null)
    throw new NullReferenceException("The MetadataExporter object passed to the ExporterBindingElement is null.");
  if (policyContext == null)
    throw new NullReferenceException("The PolicyConversionContext object passed to the ExporterBindingElement is null.");

  XmlElement elem = doc.CreateElement(name1, ns1);
  elem.InnerText = "My custom text.";
  XmlAttribute att = doc.CreateAttribute("MyCustomAttribute", ns1);
  att.Value = "ExampleValue";
  elem.Attributes.Append(att);
  XmlElement subElement = doc.CreateElement("MyCustomSubElement", ns1);
  subElement.InnerText = "Custom Subelement Text.";
  elem.AppendChild(subElement);
  policyContext.GetBindingAssertions().Add(elem);
  Console.WriteLine("The custom policy exporter was called.");
}
#endregion

#Region "IPolicyExporter Members"
Public Sub ExportPolicy(ByVal exporter As MetadataExporter, ByVal policyContext As PolicyConversionContext) Implements IPolicyExportExtension.ExportPolicy
  If exporter Is Nothing Then
    Throw New NullReferenceException("The MetadataExporter object passed to the ExporterBindingElement is null.")
  End If
  If policyContext Is Nothing Then
    Throw New NullReferenceException("The PolicyConversionContext object passed to the ExporterBindingElement is null.")

#End Region

Aşağıdaki kod örneği, önceki ilke dışarı aktarıcısının bir System.ServiceModel.Configuration.BindingElementExtensionElement uygulama yapılandırma dosyasından yüklenmesini sağlayan bir uygulamayı gösterir.

public class ExporterBindingElementConfigurationSection : BindingElementExtensionElement
{
  public ExporterBindingElementConfigurationSection()
  { Console.WriteLine("Exporter configuration section created."); }

  public override Type BindingElementType
  { get { return typeof(ExporterBindingElement); } }

  protected override BindingElement CreateBindingElement()
  { return new ExporterBindingElement(); }
}

Public Class ExporterBindingElementConfigurationSection
    Inherits BindingElementExtensionElement
  Public Sub New()
      Console.WriteLine("Exporter configuration section created.")
  End Sub

  Public Overrides ReadOnly Property BindingElementType() As Type
      Get
          Return GetType(ExporterBindingElement)

  End Property

  Protected Overrides Function CreateBindingElement() As BindingElement
      Return New ExporterBindingElement()
  End Function
End Class
