IReceiveMessageCallback 인터페이스

정의

네임스페이스:

System.ServiceModel.Activities

어셈블리:

System.ServiceModel.Activities.dll

Receive 및 ReceiveParametersContent 활동에서 서비스 메시지를 받을 때 실행되는 콜백을 구현합니다.

public interface class IReceiveMessageCallback

public interface IReceiveMessageCallback

type IReceiveMessageCallback = interface

Public Interface IReceiveMessageCallback

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.");
        }
    }
}

메서드

OnReceiveMessage(OperationContext, ExecutionProperties)

서비스 메시지를 받으면 실행됩니다.
