.NET - copy data from specific segment:offset

Question

Referring to this topic: Access memory address in c# , I'm trying to understand how to address a memory location and extract data by knowing its hexadecimal segment:offset. Also, I believe the size can be variable. I would appreciate any advice on proceeding with this.

Answer 1

Well, if you want trouble...

        int bufSize = 12;

        IntPtr ptr = (IntPtr) (0xffff *16U + 5);                  

        byte[] data = new byte[bufSize];
        Marshal.Copy(ptr, data, 0, bufSize);

Answer 2

Managed applications run on platforms with a linear address space. There is no segment, there is no offset. There is only address and you can read and write at any address through Marshal.Copy .
