Parameters

t
Type

A type that represents an interface or class.

Returns

The last VTBL slot of the interface when exposed to COM. If the t parameter is a class, the returned VTBL slot is the last slot in the interface that is generated from the class.

Attributes

Remarks

This method returns the zero-based, v-table number for an interface or a class. When used on a class, the slot number returned refers to the class interface for the class. If the class interface is auto-dispatch, this method always returns -1 to indicate that the dispatch-only interface does not expose a v-table to managed clients. You can use GetEndComSlot and Marshal.GetStartComSlot in conjunction with Marshal.GetMethodInfoForComSlot to pass slots within a specified range. For additional information, see Introducing the class interface.
