3/28/2014
This method adds an item to the end of the IXRResourceDictionaryCollection collection and retrieves the index that indicates where it was added.
Syntax
virtual HRESULT STDMETHODCALLTYPE Add(
__in IXRDependencyObject* pObject,
__out_opt int* pIndex
) = 0;
Parameters
- pObject
[in] Pointer to an IXRDependencyObject object that represents an item to add to this collection.
- pIndex
[out] Optional. Pointer to an integer value that indicates the zero-based index that describes the location of the item added to this collection.
