com interop - How can I delete a SAFEARRAY returned from a .NET function in native code? -

I am hosting a .NET library in my C ++ program using the following methods, although the complete list Do not have:

  CorBindToRuntimeEx () GetDefaultDomain () CreateInstance () GetIDsOfNames ()   
 and finally call on  invoke ()  Please.  
 This works well, but whenever a .NET function returns an array, such as:  
  public int [] getArray () {int [ ] I = {0, 1, 2, 3}; Return i; }   
 In this case, the function is a  VARIANT  type  VT_SAFEARRAY | VT_I4 . I have tried to delete  delete  and  []  on both the descriptor and PVDIT member, and it always fails. I have tried  SafeArrayDestroy ()  descriptor, which succeeds but corrupts the heap, I  SafeArrayDestroyData ()  on  variant.parray-> gtc: pvData < / Code>, but works properly, but  SafeArrayDestroyDescriptor ()  corrupts the pile again, I'm still leaking the array descriptor.  
 So, how can I choose SAFEARRAY descriptor and plug this memory leak?   
 
 
 impossible to guess without seeing the code  
 You should use the Variation Clar ().
