Retrieves the last slot in the virtual function table (v-table or VTBL) of a type when exposed to COM.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Type
A type that represents an interface or class.
Return ValueType: System.Int32
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.
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-dual, this method always returns -1 to indicate that the dispatch-only interface does not expose a v-table to managed clients. You can use and Marshal.GetStartComSlot in conjunction with Marshal.GetMethodInfoForComSlot to pass slots within a specified range. For additional information, see Introducing the Class Interface.
