⑴ C/C++编程遍历文件夹，统计当前文件个数，输出文件名
标准C是没有目录相关的函数的CFree是16位的吧,那就更不用想了.貌似只能内嵌汇编使用dos中断来完成.还是换编译器吧devcpp codeblock vc8 之类的都很好【cmail】:这个要用到windows APIHANDLE FindFirstFile( LPCTSTR lpFileName, LPWIN32_FIND_DATA lpFindFileData);BOOL FindNextFile( HANDLE hFindFile, LPWIN32_FIND_DATA lpFindFileData);WIN32_FIND_DATA【CHROX】:在Win32平台下不用windows api，有好多功能实现起来都很费劲，特别是系统相关的再说用api又不是什么丢人的事。开发可移植程序除外。用FindFirstFile和FindNextFile两个api很容易实现////////////////////////////////////////////////void FindFile(LPCTSTR lpszPath) { TCHAR szFind[MAX_PATH]; lstrcpy(szFind,lpszPath); if(!IsRoot(szFind)) lstrcat(szFind,"\\"); lstrcat(szFind,"*.*"); WIN32_FIND_DATA wfd; HANDLE hFind=FindFirstFile(szFind,&wfd); if(hFind==INVALID_HANDLE_VALUE) return; do{ if(lstrcmp(wfd.cFileName,".")==0||lstrcmp(wfd.cFileName,"..")==0) continue; char szFile[MAX_PATH]; lstrcpy(szFile,lpszPath); if(!IsRoot(szFile)) lstrcat(szFile,"\\"); lstrcat(szFile,wfd.cFileName); if((GetFileAttributes(szFile)&FILE_ATTRIBUTE_DIRECTORY)==FILE_ATTRIBUTE_DIRECTORY){ FindFile(szFile); //递归 }else { } //Do your things } } while (FindNextFile(hFind,&wfd)); CloseHandle(hFind); }【Geomatic】:原来FindFirstFile和FindNextFile是WINDOWS的API 我晕 我以为是C++的函数库里的东西呢我明白了 我找到的代码和CHROX的差不多#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];<br>lstrcpy(szFind, lpszPath);<br>if (!IsRoot(szFind))<br>lstrcat(szFind, "\\");<br>lstrcat(szFind, "*.*"); // 找所有文件<br>WIN32_FIND_DATA wfd;<br>HANDLE hFind = FindFirstFile(szFind, &wfd);<br>if (hFind == INVALID_HANDLE_VALUE) // 如果没有找到或查找失败<br>return;<br><br>do<br>{<br>if (wfd.cFileName[0] == '.')<br>continue;

// 如果找到的是目录，则进入此目录进行递归<br>}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;}谢谢大家的帮助【Geomatic】:这个怎么给你们给分啊 那个分有用吗 刚申请的 好多功能不会用啊【cmail】:点上面的“管理”。【CHROX】:分可是个好东西。呵呵，你以后就明白了。【jixingzhong】:DEV C++, 利用链表实现目录内所有文件列表显示#include <stdio.h>#include <dirent.h>/*#include <alloc.h>*/#include <string.h>void main(int argc,char *argv[]){ DIR *directory_pointer;

⑵ 在windows下 怎么用c语言遍历文件夹要用纯c的
什么叫纯C？用C语言遍历文件肯定需要用到函数，标准C下貌似没有这个函数内，但容是使用VC的函数库可能可以实现，如果实在不行可以用第三方函数库，，，还不行的话用system("command");引用dos命令可以遍历，
⑶ 如何遍历目录,找出磁盘所有目录的dll文件
这是 a.bat 批命令程序，遍历目录,找出磁盘所有目录的dll文件，存放结果到 temp.txt 文件里。内temp.txt 文件可供C程序进一步处容理用，一行一个文件名，含全路径名。C 程序 用system("a.bat"); 调用即可。若从某盘根目录进入寻找，添：cd C:\\D:cd D:\\这类命令即可。@echo off setlocal enabledelayedexpansion for /f %%i in ('dir /b /s "*.dll"') do ( echo %%iset str=%%i set str=!str:\=\\! echo !str! >> temp.txt) @echo on
⑷ vc如何遍历全盘(包括子目录)
int count_file(char *dir){ _finddata_t p;//定义一个结构体存放文件属性int n,n1;char *a;n=strlen(dir);a=new char [n+100];n1=0;strcpy(a,dir);strcat(a,"\\*.*");if((n=_findfirst(a,&p))!=-1L)//调用文件查找函数{if(strcmp(p.name,".")&&strcmp(p.name,"..")){if((p.attrib&_A_SUBDIR))//文件是否为文件夹{int n2=strlen(dir)+strlen(p.name);char *b=new char [n2+10];strcpy(b,dir);strcat(b,"\\");strcat(b,p.name);n1+=count_file(b);//递归调用 作用是返回文件夹内的文件总数n1++;delete(b);}}while(_findnext(n,&p)==0)//寻找下一个文件{if(strcmp(p.name,".")&&strcmp(p.name,"..")){if((p.attrib&_A_SUBDIR)){int n2=strlen(dir)+strlen(p.name);char *b=new char [n2+10];strcpy(b,dir);strcat(b,"\\");strcat(b,p.name);n1+=count_file(b);delete(b);n1++;}else n1++;}}_findclose(n);//结束寻找}delete(a);return n1;//返回文件总个数}
⑸ VC6.0编译环境下遍历文件夹的源代码
