A pointer to the managed object's IUnknown interface.

Attributes

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.
