Public Delegate Function ObjectCreationDelegate(aggregator As IntPtr) As IntPtr

Parameters

aggregator: IntPtr
nativeint

A pointer to the managed object's IUnknown interface.

Return Value

IntPtr

nativeint

An IntPtr object that represents the IUnknown interface of the COM object.

Attributes: ComVisibleAttribute

Remarks

This delegate is called to create a COM object as an alternative to CoCreateInstance when a managed object needs to create a new instance of its unmanaged portion. The IUnknown interface of the managed object is passed as a parameter and the delegate should return the IUnknown interface of the unmanaged object. Both interfaces are passed as type IntPtr to avoid marshaling.

Every derived class of Delegate and MulticastDelegate has a constructor and an Invoke method.

Extension Methods

GetMethodInfo(Delegate)

Gets an object that represents the method represented by the specified delegate.
