Gets a value that indicates whether an operation returns a reply message.
Namespace: System.ServiceModel.Description
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Syntax
'Declaration
Public ReadOnly Property IsOneWay As Boolean
public bool IsOneWay { get; }
Property Value
Type: System.Boolean
true if this method receives a request message and returns no reply message; otherwise, false. The default is false.
Remarks
Use the IsOneWay property to indicate that an operation does not return a reply message. This type of operation is useful for notifications or event-style communication, especially in two-way communication.
If the IsOneWay property is set to false (the default), even methods that return void result in a reply message. In this case, the infrastructure creates and sends an empty message to indicate to the caller that the method has returned.
