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.

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.
