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("...\n");

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 }
