WsdlContractConversionContext.GetOperation(OperationDescription) 메서드

정의

네임스페이스:

System.ServiceModel.Description

어셈블리:

System.ServiceModel.dll

지정한 작업 설명에 대한 작업을 반환합니다.

public:
 System::Web::Services::Description::Operation ^ GetOperation(System::ServiceModel::Description::OperationDescription ^ operation);

public System.Web.Services.Description.Operation GetOperation (System.ServiceModel.Description.OperationDescription operation);

member this.GetOperation : System.ServiceModel.Description.OperationDescription -> System.Web.Services.Description.Operation

Public Function GetOperation (operation As OperationDescription) As Operation

매개 변수

operation

OperationDescription

요청된 OperationDescription에 대한 Operation입니다.

반환

Operation

지정한 작업 설명에 대한 작업입니다.

예외

KeyNotFoundException

값이 없는 경우

ArgumentNullException

값이 null인 경우

예제

다음 코드 예제에서는 WsdlContractConversionContext 및 WsdlPortType 속성을 사용하여 내보낸 메타데이터에 Contract를 사용하여 사용자 지정 WSDL 주석을 추가하는 방법을 보여 줍니다. 이 메서드는 작업을 내보낼 때 작업 설명을 반복하고 System.Web.Services.Description.Operation 메서드를 호출하여 연결된 각 GetOperation을 찾습니다.
