When you call SafeArrayAccessData, the pointer to the safe array’s data is specified as an additional output parameter: c++ Copy // Pointer to safe array’s data, returned as output parameter BYTE* pData = nullptr; hr = SafeArrayAccessData(psa, reinterpret_cast<void**>(&pData)); if (...
array storing 4-byte-signed integers, on the C++ side you’d have CComSafeArray<int>, and the corresponding PInvoke VarEnum type would be VT_I4 (meaning signed integer of 4-byte size). The safe array is mapped to a byte[] array in C#, and that’s passed as an out parameter. ...
a pointer to the actual array or contiguous array section is passed as the argument. If the data is non-contiguous, such as an array section of non-contiguous

Problem is, the "foo" method is seeing the incoming arguments as a single argument of type Integer[], when I want it to see them as seperate arguments of type Integer. Is there a way to do this, without knowing how many parameters will be passed? Philippe Desrosiers Ranch Hand Posts:...

Arrays are always passed by reference to a method. Since the CLR doesn't support the notion of constant parameters, this means that the method is able to change the elements in the array. If you don't want to allow the method to modify the elements, then you must make a copy of the...
