C# how can I make this function run in parallel ?

<pre> public void ReadAOB(string Scancode)
        {
            if ((int)processhandle > 0)
            {
                IntPtr bytesRead = IntPtr.Zero;
                long MaxAddress = 0;
                if(isbit64)
                     MaxAddress = 0x7fffffffffffffff;
                else
                    MaxAddress = 0x7fffffff;
                long address = 0;
                addresses.Clear();
                do
                {
                    MEMORY_BASIC_INFORMATION m;
                    int result = VirtualQueryEx(processhandle, (IntPtr)address, out m, (uint)Marshal.SizeOf(typeof(MEMORY_BASIC_INFORMATION)));

                    if (m.Protect == AllocationProtectEnum.PAGE_READWRITE)
                    {
                        byte[] buffer = new byte[(int)m.RegionSize];
                        // IntPtr buffer = IntPtr.Zero;
                        ReadProcessMemory(processhandle, m.BaseAddress, buffer, (int)m.RegionSize, out bytesRead);
                        BoyerAlgo(m.BaseAddress, buffer, Scancode, ref addresses);
                    }
                    if (address == (long)m.BaseAddress + (long)m.RegionSize)
                        break;
                    address = (long)m.BaseAddress + (long)m.RegionSize;
                } while (address <= MaxAddress);

            }
        }
