Question

VC++程序如何遍历一个文件夹下面的所有子文件夹下的文件？

Answer 1

find(char * lpPath)
{
char szFind[MAX_PATH];
WIN32_FIND_DATA FindFileData;
strcpy(szFind,lpPath);
strcat(szFind,"*.*");
HANDLE hFind=::FindFirstFile(szFind,&FindFileData);
if(INVALID_HANDLE_VALUE == hFind) return;
while(TRUE)
{
if(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if(FindFileData.cFileName[0]!='.')
{
strcpy(szFile,lpPath);
strcat(szFile,"");
strcat(szFile,FindFileData.cFileName);
find(szFile);
}
}
else
{
cout << FindFileData.cFileName;
}
if(!FindNextFile(hFind,&FindFileData)) break;
}
FindClose(hFind);
}

#include <afxwin.h>
#include <iostream>

using namespace std;

void Recurse(LPCTSTR pstr)
{
CFileFind finder;

// build a string with wildcards

CString strWildcard(pstr);
strWildcard += _T("\\*.*");

// start working for files

BOOL bWorking = finder.FindFile(strWildcard);

while (bWorking)
{
bWorking = finder.FindNextFile();

// skip . and .. files; otherwise, we'd

// recur infinitely!

if (finder.IsDots())
continue;

CString sFileName = finder.GetFileName();
cout << (LPCTSTR)sFileName << endl;//输出查找文件夹下的所有文件名

}

finder.Close();
}

int main()
{
if (!AfxWinInit(GetModuleHandle(NULL), NULL, GetCommandLine(), 0))//初始化MFC

cout << "panic!" << endl;
else
Recurse(_T("C:"));
return 0;
}
