IPolicyExportExtension.ExportPolicy 메서드

정의

네임스페이스:

System.ServiceModel.Description

어셈블리:

System.ServiceModel.dll

바인딩에 대한 사용자 지정 어설션을 내보내기 위해 포함할 구현입니다.

public:
 void ExportPolicy(System::ServiceModel::Description::MetadataExporter ^ exporter, System::ServiceModel::Description::PolicyConversionContext ^ context);

public void ExportPolicy (System.ServiceModel.Description.MetadataExporter exporter, System.ServiceModel.Description.PolicyConversionContext context);

abstract member ExportPolicy : System.ServiceModel.Description.MetadataExporter * System.ServiceModel.Description.PolicyConversionContext -> unit

Public Sub ExportPolicy (exporter As MetadataExporter, context As PolicyConversionContext)

매개 변수

exporter

MetadataExporter

내보내기 프로세스를 수정하는 데 사용할 수 있는 MetadataExporter입니다.

context

PolicyConversionContext

사용자 지정 정책 어설션을 삽입하는 데 사용할 수 있는 PolicyConversionContext입니다.

예제

다음 코드 예제에서는 IPolicyExportExtension .BindingElement 이 예제에서는 사용자 지정 바인딩 요소가 바인딩 수준에서 WSDL 파일에 연결됩니다.

  public override Type BindingElementType

설명

다양한 범위에서 이미 내보낸 정책 어설션 컬렉션을 가져오려면 GetBindingAssertions, GetMessageBindingAssertions 및 GetOperationBindingAssertions 메서드를 사용합니다. 그런 다음 적절한 컬렉션에 개체를 추가합니다 IPolicyExportExtension .
