ComInterfaceType Enumeration

.NET Framework 4.5

Identifies how to expose an interface to COM.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public enum ComInterfaceType

	Member name	Description
	InterfaceIsDual	Indicates that the interface is exposed to COM as a dual interface, which enables both early and late binding. InterfaceIsDual is the default value.
	InterfaceIsIDispatch	Indicates that an interface is exposed to COM as a dispinterface, which enables late binding only.
	InterfaceIsIInspectable	Indicates that an interface is exposed to COM as a Windows Runtime interface.
	InterfaceIsIUnknown	Indicates that an interface is exposed to COM as an interface that is derived from IUnknown, which enables only early binding.

This enumeration works in conjunction with the InterfaceTypeAttribute attribute.
