C# how to get Byte[] from IntPtr

Question

I have a .dll(not my own) that has a delegate. This delegate Callback function is:
"CallBackFN(ushort opCOde, IntPtr payload, uint size, uint localIP)"

How can i convert IntPtr to Byte[]? I think that payload is actually Byte[]. If it's not Byte[] and it's something else would i lose some data?

Have you looked into Marshal.Copy?
