 ## 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-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 <xref:System.Runtime.InteropServices.Marshal.GetEndComSlot%2A> and <xref:System.Runtime.InteropServices.Marshal.GetStartComSlot%2A?displayProperty=nameWithType> in conjunction with <xref:System.Runtime.InteropServices.Marshal.GetMethodInfoForComSlot%2A?displayProperty=nameWithType> to pass slots within a specified range. For additional information, see [Introducing the Class Interface](https://msdn.microsoft.com/library/733c0dd2-12e5-46e6-8de1-39d5b25df024).
