为什么ReadProcessMemory总是返回false？

Question

不知道为什么，但是对于某些ReadProcessMemory总是返回false。总是这样导入它：

[DefaultDllImportSearchPaths(Kernel32.Path)]
[DllImport(Kernel32.Dll)]
private static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, [Out] byte[] lpBuffer, int nSize, IntPtr lpNumberOfBytesRead);

这是运行ReadProcessMemory(IntPtr HandleWithAllAccess, IntPtr ProcessBaseAddress, byte[] BufferSizeOf500, int TheSize500, IntPtr.Zero);

的结果

Note: just so people don't start asking unrelated questions, Kernel32 is a class with the dll name and the path where to find it

Answer 1

读取操作进入进程的不可访问区域，这就是为什么它返回false的原因。感谢Jeroen Mostert链接了文档，从现在开始我将SetLastError设置为true。
