    Hi Im trying to import C++ DLL the C++ function is : _DLL_EXPORT int test(unsigned char * Data1, unsigned int * iDataLen , unsigned char def=NULL); My code in C# [DllImport("MyDLL.dll")] public static extern int test(byte[] Data1, ref uint iDataLen ); when i call this function : byte [] data1 = new byte []{0x01,0x02,0x03}; uint iDataLen = 3; test(data1 ,ref iDataLen); I get access violation exception : "Attempted to read or write protected memory. This is often an indication that other memory is corrupt" Help will be highly appreciated :)
