VC++ 遍历文件夹

 1     char szFind[MAX_PATH] = {0};
 2     strcpy_s(szFind, MAX_PATH, m_szDir);
 3     strcat_s(szFind, "\*.*");
 4 
 5     WIN32_FIND_DATA wfd;
 6     HANDLE hFind = ::FindFirstFile(MultiByteToWideChar(szFind), &wfd);
 7     if (INVALID_HANDLE_VALUE != hFind)
 8     {
 9         while (TRUE)
10         {
11             if (wfd.cFileName[0] != _T('.'))// 不是当前目录或者父目录
12             {
13                 printf("...
");
14             }
15             if (!::FindNextFile(hFind, &wfd)) break;
16         }
17     }
18 
19     FindClose(hFind);

其中MultiByteToWideChar(char*)函数是用来将char数组转化成wchar_t字符串的。

1 wchar_t* MultiByteToWideChar(char* ch)
2 {
3     int num = MultiByteToWideChar(0,0,ch,-1,NULL,0);
4     wchar_t *wide = new wchar_t[num];
5     MultiByteToWideChar(0,0,ch,-1,wide,num);
6     return wide;
7 }
