Could someone provide an example of how to read the value of 006F6D59 (random address) and retrieve an int value.

Code:
#include <iostream>
#include <windows.h>
using namespace std;

DWORD pid;
HWND gameWindow;
HANDLE gameProcess;
DWORD dongs;

int main(void)
{
   gameWindow = FindWindow(NULL, TEXT("Minesweeper"));
   if (gameWindow == NULL){
      std::cout << "Oh god.\n";      
   }
   GetWindowThreadProcessId(gameWindow, &pid);
   gameProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);

   ReadProcessMemory (gameProcess, (void*)0x0100579C, &dongs, sizeof dongs, NULL);
   std::cout << dongs << "\nDone.\n";
   return 0;
}


bored. quick example, reads your time in minesweeper. modify as you see fit.

I assume the readprocess/writeprocess memory method works somewhat the same in C#?

Heres a few examples of reading / writing to memory via C#:
http://www.codeproject.com/KB/trace/minememoryreader.aspx
http://www.codeproject.com/KB/trace/freecellreader.aspx
http://www.codeproject.com/KB/cs/sojaner_memory_scanner.aspx

The API will be setup the same, the method of using it might be a little different in each language such as importing it to be usable and so on. But the params and call are all static to the API and don't change unless the operating system changes them in an update.

pinvoke.net is your (read: lazy way out) friend when it comes to using API's in C#.
