Remarks

The BStrWrapper class controls how the wrapped object is marshaled when passed as VARIANT. You can wrap a String object in a BStrWrapper object to marshal it as VT_BSTR. BStrWrapper is useful when passing a null string to unmanaged code. Without BStrWrapper, a null string is passed as VT_EMPTY; however, wrapping the string with BStrWrapper ensures that the null string is passed as VT_BSTR.
