IReceiveMessageCallback.OnReceiveMessage 메서드

정의

네임스페이스:

System.ServiceModel.Activities

어셈블리:

System.ServiceModel.Activities.dll

서비스 메시지를 받으면 실행됩니다.

public:
 void OnReceiveMessage(System::ServiceModel::OperationContext ^ operationContext, System::Activities::ExecutionProperties ^ activityExecutionProperties);

public void OnReceiveMessage (System.ServiceModel.OperationContext operationContext, System.Activities.ExecutionProperties activityExecutionProperties);

abstract member OnReceiveMessage : System.ServiceModel.OperationContext * System.Activities.ExecutionProperties -> unit

Public Sub OnReceiveMessage (operationContext As OperationContext, activityExecutionProperties As ExecutionProperties)

매개 변수

operationContext

OperationContext

메시지를 받는 작업 컨텍스트입니다.

activityExecutionProperties

ExecutionProperties

워크플로 내에서 사용할 수 있는 실행 속성 집합입니다.

예제

다음 예제에서는 IReceiveMessageCallback 인터페이스를 구현하여 메시지를 받을 때 메시지 머리글에 액세스하는 방법을 보여 줍니다.

class ReceiveInstanceIdCallback : IReceiveMessageCallback
{
    public const string HeaderName = "InstanceIdHeader";
    public const string HeaderNS = "http://Microsoft.Samples.AccessingOperationContext";

    public void OnReceiveMessage(System.ServiceModel.OperationContext operationContext, System.Activities.ExecutionProperties activityExecutionProperties)
    {
        try
        {
            Guid instanceId = operationContext.IncomingMessageHeaders.GetHeader<Guid>(HeaderName, HeaderNS);
            Console.WriteLine("Received a message from a workflow with instanceId = {0}", instanceId);
        }
        catch (MessageHeaderException)
        {
            Console.WriteLine("This message must not be from a workflow.");
        }
    }
}
