Syntax

public:
[SecurityCriticalAttribute]
static Object^ GetComObjectData(
	Object^ obj,

)

obj: Type: System::Object^
The COM object that contains the data that you want.

key: Type: System::Object^
The key in the internal hash table of obj to retrieve the data from.

Return Value

Exceptions

Exception	Condition
ArgumentNullException	obj is null. -or- key is null.
ArgumentException	obj is not a COM object. -or- obj is a Windows Runtime object.

All COM objects wrapped in a Runtime Callable Wrapper have an associated hash table, which GetComObjectData retrieves. Marshal::SetComObjectData adds data to the hash table. You should never have to call either method from your code.
