IOperationInvoker Interface

Definition

Namespace:

System.ServiceModel.Dispatcher

Assembly:

System.ServiceModel.dll

Declares methods that take an object and an array of parameters extracted from a message, invoke a method on that object with those parameters, and return the method's return value and output parameters.

C#

public interface IOperationInvoker

Remarks

Implement the IOperationInvoker interface to control the conversion from an untyped object and array of parameters to a strongly-typed method call on that object. It has a synchronous Invoke method, which takes an instance and set of inputs of type object and returns an object and a set of outputs of type object. It also has a InvokeBegin and InvokeEnd variant. The IsSynchronous property specifies whether the synchronous or asynchronous method should be used.

Properties

IsSynchronous

Gets a value that specifies whether the Invoke(Object, Object[], Object[]) or InvokeBegin(Object, Object[], AsyncCallback, Object) method is called by the dispatcher.

Methods

AllocateInputs()	Returns an Array of parameter objects.
Invoke(Object, Object[], Object[])	Returns an object and a set of output objects from an instance and set of input objects.
InvokeBegin(Object, Object[], AsyncCallback, Object)	An asynchronous implementation of the Invoke(Object, Object[], Object[]) method.
InvokeEnd(Object, Object[], IAsyncResult)	The asynchronous end method.
