读取unicode日志文件并清除记录的垃圾文件

//读取unicode文件，并清除记录的垃圾文件//参数1:日志文件路径bool ReadFilePath(const wchar_t *DataFilePath){    wchar_t ChBuffer = L'\0'; //将要从文件读取的单个字符    wchar_t CleanFilePath[256] = L"\0"; //将要清除的垃圾文件路径    DWORD ReadNumber = 0; //已经读取的路径拥有的字符数量    DWORD dwReadSize = 100;//已经读取多少数据    HANDLE handle_File = CreateFile(DataFilePath,                                    GENERIC_READ,                                    0,                                    NULL,                                    OPEN_EXISTING,                                    FILE_ATTRIBUTE_NORMAL,                                    NULL);                while(ReadFile(handle_File,&ChBuffer,2,&dwReadSize,NULL))        {            if(dwReadSize == 0)            {                wprintf(L"检测到文件结尾\n");                break;            }            if(ChBuffer == L'\r')                continue;            if(ChBuffer == L'\n')            {                CleanFilePath[ReadNumber] = L'\0';                wprintf(L"已清除%s\n",CleanFilePath);                DeleteFile(CleanFilePath);                ReadNumber = 0;            }            else                CleanFilePath[ReadNumber++] = ChBuffer;        }    // 释放文件对象资源    CloseHandle(handle_File) ;} 一开始因为不了解，使用了_wfopen_s,fgetwc系列函数，结果遇到了unicode文本乱码bug然后通过，谷歌，msdn了解了，CreateFile,和ReadFile函数使用CreateFile获取句柄，ReadFile读取文本中单个字符，并判断参数&dwReadSize是否为0来检测是否到了文件结尾BOOL WINAPI ReadFile(  _In_         HANDLE hFile, //文件句柄  _Out_        LPVOID lpBuffer, //读写缓冲区  _In_         DWORD nNumberOfBytesToRead, //读取多少数据  _Out_opt_    LPDWORD lpNumberOfBytesRead,//已经读取了多少数据  _Inout_opt_  LPOVERLAPPED lpOverlapped//异步读取结构);HANDLE hFile 文件句柄，通过CreateFile来获得LPVOID lpBuffer 保存读取的字符DWORD nNumberOfBytesToRead，一个wchar_t字符为2个数据 LPDWORD lpNumberOfBytesRead, 为0时为文件结尾LPOVERLAPPED lpOverlapped //一般为空
