IReplyChannel.TryReceiveRequest Method

Returns a value that indicates whether a request is received before a specified interval of time elapses.

Namespace:  System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

bool TryReceiveRequest(
	TimeSpan timeout,
	out RequestContext context


Type: System.TimeSpan

The TimeSpan that specifies how long the receive of a request operation has to complete before timing out and returning false.

Type: System.ServiceModel.Channels.RequestContext

The RequestContext received.

Return Value

Type: System.Boolean
true if a request message is received before the specified interval of time elapses; otherwise false.

Use TryReceiveRequest(TimeSpan, RequestContext) when it is acceptable for the current thread to be blocked while it waits for a request message to arrive in the queue. The thread is blocked up to the specified timeout. If you need the application processing to continue without waiting, use the asynchronous BeginTryReceiveRequest(TimeSpan, AsyncCallback, Object) method.

Notes to Implementers

The operation returns false if the specified timeout is exceeded.

The following code illustrates how to implement this method:

public bool TryReceiveRequest(TimeSpan timeout, out RequestContext requestContext)
    bool result;

    while (true)
        result = this.InnerChannel.TryReceiveRequest(timeout, out requestContext);
        if (!result || ProcessRequestContext(ref requestContext))

    return result;
