C/C++中关于遍历文件夹的操作

#include <windows.h>#include <stdio.h> void FindFileInDir(char* rootDir, char* strRet){char fname[256];ZeroMemory(fname,256);WIN32_FIND_DATA fd;ZeroMemory(&fd, sizeof(WIN32_FIND_DATA));HANDLE hSearch;char filePathName[256];char tmpPath[256];ZeroMemory(filePathName, 256);ZeroMemory(tmpPath, 256);strcpy(filePathName, rootDir);BOOL bSearchFinished = FALSE;if( filePathName[strlen(filePathName) -1] != '//' ){strcat(filePathName, "//");}strcat(filePathName, "*");hSearch = FindFirstFile(filePathName, &fd);//Is directoryif( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)&& strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ) {strcpy(tmpPath, rootDir);strcat(tmpPath, fd.cFileName);FindFileInDir(tmpPath, strRet);}else if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ){sprintf(fname, "%-50.50s", fd.cFileName);strcat(strRet + strRet[strlen(strRet)] , fname);}while( !bSearchFinished ){if( FindNextFile(hSearch, &fd) ){if( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)&& strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ) {strcpy(tmpPath, rootDir);strcat(tmpPath, fd.cFileName);FindFileInDir(tmpPath, strRet);}else if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ){sprintf(fname, "%-50.50s", fd.cFileName);strcat(strRet + strRet[strlen(strRet)] , fname);}}else{if( GetLastError() == ERROR_NO_MORE_FILES ) //Normal Finished{bSearchFinished = TRUE;}elsebSearchFinished = TRUE; //Terminate Search}}FindClose(hSearch);}main(){}

 

把这段代码复制　另存为后缀为　．ＣＰＰ　文件　然后编译　可以编译

在来看看你的那个
花了几分钟改成了　Ｃ语言
贴出来了
你把下边的代码复制
另存为后缀为　.Ｃ　的文件
然后　编译　就可以了
#include <windows.h>#include <stdio.h> void FindFileInDir(char* rootDir, char* strRet){char fname[256]; WIN32_FIND_DATA fd; HANDLE hSearch;char filePathName[256];char tmpPath[256];BOOL bSearchFinished = FALSE;ZeroMemory(fname,256);ZeroMemory(&fd, sizeof(WIN32_FIND_DATA));ZeroMemory(filePathName, 256);ZeroMemory(tmpPath, 256);strcpy(filePathName, rootDir);if( filePathName[strlen(filePathName) -1] != '//' ){strcat(filePathName, "//");}strcat(filePathName, "*");hSearch = FindFirstFile(filePathName, &fd);//Is directoryif( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)&& strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ) {strcpy(tmpPath, rootDir);strcat(tmpPath, fd.cFileName);FindFileInDir(tmpPath, strRet);}else if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ){sprintf(fname, "%-50.50s", fd.cFileName);strcat(strRet + strRet[strlen(strRet)] , fname);}while( !bSearchFinished ){if( FindNextFile(hSearch, &fd) ){if( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)&& strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ) {strcpy(tmpPath, rootDir);strcat(tmpPath, fd.cFileName);FindFileInDir(tmpPath, strRet);}else if( strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..") ){sprintf(fname, "%-50.50s", fd.cFileName);strcat(strRet + strRet[strlen(strRet)] , fname);}}else{if( GetLastError() == ERROR_NO_MORE_FILES ) //Normal Finished{bSearchFinished = TRUE;}elsebSearchFinished = TRUE; //Terminate Search}}FindClose(hSearch);}main(){char abc[25]="c://TEXTRO";char cde[25]="exe";FindFileInDir(abc,cde);}

 

 

 

如何用C遍历一个文件夹中的所有文件:

#include <stdio.h>#include <windows.h>BOOL IsRoot(LPCTSTR lpszPath){TCHAR szRoot[4];wsprintf(szRoot, "%c://", lpszPath[0]);return (lstrcmp(szRoot, lpszPath) == 0);}void FindInAll(::LPCTSTR lpszPath){TCHAR szFind[MAX_PATH];lstrcpy(szFind, lpszPath);if (!IsRoot(szFind))lstrcat(szFind, "//");lstrcat(szFind, "*.*"); // 找所有文件WIN32_FIND_DATA wfd;HANDLE hFind = FindFirstFile(szFind, &wfd);if (hFind == INVALID_HANDLE_VALUE) // 如果没有找到或查找失败return;do{if (wfd.cFileName[0] == '.')continue; // 过滤这两个目录if (wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY){TCHAR szFile[MAX_PATH];if (IsRoot(lpszPath))wsprintf(szFile, "%s%s", lpszPath, wfd.cFileName);elsewsprintf(szFile, "%s//%s", lpszPath, wfd.cFileName);FindInAll(szFile); // 如果找到的是目录，则进入此目录进行递归}else{TCHAR szFile[MAX_PATH];if (IsRoot(lpszPath))wsprintf(szFile, "%s%s", lpszPath, wfd.cFileName);elsewsprintf(szFile, "%s//%s", lpszPath, wfd.cFileName);printf("%s/n",szFile);// 对文件进行操作}} while (FindNextFile(hFind, &wfd));FindClose(hFind); // 关闭查找句柄}int main(int argc, char* argv[]){FindInAll("g://music");return 0;}
