The native code also needs override paired with virtual also! Here is an example taken out of Microsofts documentation:

value class MOctetString
{
   unsigned int length;
   array<unsigned char>^ value;
};

Is there a better way to copy the data into the ArrayList, and is
there a more suitable structure than a ArryList to handle binary data of different lengths?

<br />
array<unsigned char>^ value = {'a','b','c'};<br />
char* ptr = new char[value->Length];<br />
Marshal::Copy(value,0,(IntPtr)ptr,value->Length);<br />

<br />
int length = 3;<br />
char str[] =  {'d','e','f'};<br />
char* pStr = &str[0];<br />
array<unsigned char>^ strArr = gcnew array<unsigned char>(length);<br />
Marshal::Copy((IntPtr)pStr,strArr,0,length);<br />
