static bool TryGetComInstance(System::Object ^ obj, [Runtime::InteropServices::Out] IntPtr % unknown);public static bool TryGetComInstance (object obj, out IntPtr unknown);static member TryGetComInstance : obj * nativeint -> boolPublic Shared Function TryGetComInstance (obj As Object, ByRef unknown As IntPtr) As BooleanParameters
- obj
- Object
The managed wrapper.
- unknown
-
IntPtr
nativeint
The unmanaged COM object.
Returns
true if the wrapper was resolved to an external COM object, otherwise false.
Remarks
If a COM object is returned, the caller is expected to call Release() on the object. This can be done through an API like Release(IntPtr). Since this API is required to interact directly with the external COM object, QueryInterface(), it's important for the caller to understand the COM object may have apartment affinity. Therefore, if the current thread is not in the correct apartment or the COM object is not a proxy, this call may fail.
