一个读取内存的问题，希望高手可以解答！


private int GetProcessID(string title)
        {
            Process[] arrayProcess = Process.GetProcesses();            foreach (Process p in arrayProcess)
            {
                if (p.MainWindowTitle.IndexOf(title) != -1)
                {
                    return p.Id;
                }
            }            return 0;
        }        private int GetRead(string title, IntPtr baseAddress)
        {
            byte[] buffer = new byte[4];
            IntPtr byteAddress = Marshal.UnsafeAddrOfPinnedArrayElement(buffer, 0);
            IntPtr hProcess = OpenProcess(PROCESS_ALL_ACCESS, false, GetProcessID(title));
            ReadProcessMemory(hProcess, baseAddress, byteAddress, buffer.Length, hProcess);
            CloseHandle(hProcess);
            return Marshal.ReadInt32(byteAddress);
        }        [DllImportAttribute("kernel32.dll", EntryPoint = "ReadProcessMemory")]
        public static extern bool
            ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, IntPtr lpBuffer, int nSize, IntPtr lpNumberOfBytesRead);        [DllImportAttribute("kernel32.dll", EntryPoint = "OpenProcess")]
        public static extern IntPtr 
            OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId);        [DllImport("kernel32.dll")]
        private static extern void CloseHandle(IntPtr hObject);        public const int PROCESS_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED | (SYNCHRONIZE | 4095));        public const int STANDARD_RIGHTS_REQUIRED = 983040;        public const int SYNCHRONIZE = 1048576;
读取地址的时候报：尝试读取或写入受保护的内存。这通常指示其他内存已损坏
