IOperationInvoker Interface

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.

Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)
'Declaration
Public Interface IOperationInvoker
'Usage
Dim instance As IOperationInvoker

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.
