c++宽字符与多字节之间转换char—wchar，wchar-char



WCHAR exeFullPath[MAX_PATH];//定义wchar宽字符
  //获取转换所需的目标缓存大小 
  DWORD dBufSize = WideCharToMultiByte(CP_OEMCP, 0, exeFullPath, -1,

NULL, 0, NULL, FALSE);
  char path[MAX_PATH] = {0};//分配目标缓存
 //转换 
  int nRet = WideCharToMultiByte(CP_OEMCP, 0, exeFullPath, -1, path,

dBufSize, NULL, FALSE);
       //////////////////////////////////
反转换

char path[260];//定义char缓冲区
WCHAR wszClassName[256] = {0};//定义宽字符缓冲区
  memset(wszClassName, 0, sizeof(wszClassName));
  MultiByteToWideChar(CP_ACP, 0, path, strlen(path) + 1,

wszClassName,
   sizeof(wszClassName) / sizeof(wszClassName[0]));
