VirtualQueryEx C#

[proger]

Вот настрочил такой сканер сигнатур, но проблема в том что не хочет заполняться буфер.

(прощу не ругаться знаю что это бредокод, но все же)

Прощу исправить, буду благодарен!

var pattern = new int[] { 0xF3, 0x0F, 0x7E, 0x56, 0x10, 0xF2, 0x0F, 0x59, 0xC2, 0x66, 0x0F, 0xD6, 0x45, 0xD0, 0x66, 0x0F, 0x57, 0xD2, 0x66, 0x0F, 0x2E, 0xD0 };
			var handle = OpenProcess(0x001F0FFF, false, pID);
			long MaxAddress = 0x7fffffff;
			long address = 0;
			int bytesread;
			MEMORY_BASIC_INFORMATION mbi;
			byte[] buffer;
			mbi.BaseAddress = IntPtr.Zero;
			mbi.RegionSize = IntPtr.Zero;
			while (address <= MaxAddress)
			{
				int result = VirtualQueryEx(handle, (IntPtr)address, out mbi, (uint)Marshal.SizeOf(typeof(MEMORY_BASIC_INFORMATION)));
				if (address == (long)mbi.BaseAddress + (long)mbi.RegionSize)
					break;
				address = (long)mbi.BaseAddress + (long)mbi.RegionSize;
			}

			buffer = new byte[(uint)mbi.RegionSize];
			ReadProcessMemory(handle, mbi.BaseAddress, buffer, (int)mbi.RegionSize, out bytesread);

			var counter = 0;
			if (pattern.Length < (int)mbi.RegionSize)
			{
				for (var i = 0; i < (int)mbi.RegionSize; i++)
				{
					if (buffer[i] == pattern[0])
					{
						for (var j = 0; j < pattern.Length; j++)
						{
							if (buffer[i + j] == pattern[j])
							{
								counter++;
								if (counter == pattern.Length)
								{
									int resultq = i + (int)mbi.BaseAddress;
									return;
								}
								else
								{
									counter = 0;
								}
							}
						}
					}
				}
			}
