首先介绍下 这两个函数的原型：BOOL ReadFile(
HANDLE hFile,
LPVOID lpBuffer,
DWORD nNumberOfBytesToRead,
LPDWORD lpNumberOfBytesRead,
LPOVERLAPPED lpOverlapped
);
BOOL WriteFile(
HANDLE hFile,
LPCVOID lpBuffer,
DWORD nNumberOfBytesToWrite,
LPDWORD lpNumberOfBytesWritten,
LPOVERLAPPED lpOverlapped
);
错误提示： 当进行读写数据时候，提示无效句柄原因： 可能在某处不小心把句柄hFile，用CloseHandle给关闭了。
