为什么ReadProcessMemory总是返回false？

Question

不知道为什么，但对某些人来说，ReadProcessMemory总是返回false。始终像这样导入它：

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

下面是运行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

读操作进入了进程中无法访问的区域，这就是它返回false的原因。感谢Jeroen Mostert链接文档，从现在开始，我将把SetLastError设置为true。
