Some random notes:
Function Get(jname As String, v) As Long
Member of JDLLServerLib.JDLLServer
Get variant value from J variable.
Function GetB(jname As String, v) As Long
Member of JDLLServerLib.JDLLServer
Get variant value from J variable (BSTR).
Function GetM(jname As String, jtype As Long, jrank As Long, jshape As Long,
jdata As Long) As Long
Member of JDLLServerLib.JDLLServer
Get J variable description and memory addresses of shape and data.

I think
Console.WriteLine("Orriginal int array value : " +
(IntArrayToString(intArray)));
Console.WriteLine("J returned int array value : " +
(IntArrayToString((int[])intArray)));
should be
Console.WriteLine("Orriginal int array value : " +
(IntArrayToString(intArray)));
Console.WriteLine("J returned int array value : " +
(IntArrayToString((int[])intArrayObj)));

Here is what I get with C# 2010 Express and J602-64:
IntArray
34359738372 68719476751 180388626455 111164048 113747712 111035888
hfd IntArray
0800000004
100000000F
2A00000017
0006A03A90
0006C7A700
00069E45F0
The 32 bit C# int values look like they have been packed into 64 bit J integers
(with garbage fill at the end.)
