IRequestChannel.Request Method (Message)

Sends a message-based request and returns the correlated message-based response.

Namespace:  System.ServiceModel.Channels
Assemblies:   System.ServiceModel (in System.ServiceModel.dll)
  System.ServiceModel.Primitives (in System.ServiceModel.Primitives.dll)

Message Request(
	Message message


Type: System.ServiceModel.Channels.Message

The request Message to be transmitted.

Return Value

Type: System.ServiceModel.Channels.Message
The Message received in response to the request.

Implementations of IRequestChannel ensure that the response message is correlated with the request message.

Generally, if an implementation of IRequestChannel receives a message that is not correlated to an outstanding request, it is dropped.

The Request method can be called concurrently across multiple threads.

Passing the message into the request channel causes the message to be accessed. After you call Request, you can no longer inspect the message or call Close on the message.

If the request message is larger that the maximum message size allowed by the binding being used, a QuotaExceededException is thrown. The maximum message size is set by the MaxReceivedMessageSize property. The default value is 65536 bytes.

The following code shows how to implement this method:

public Message Request(Message message)
    return this.InnerChannel.Request(message);
