vc++遍历文件

应包含的头文件：

#include <io.h>

1. 遍历文件夹下的文件（不包括子文件夹）例如查找全部jpg图片，fileName为 [folderPath]\\*.jpg

        int fileCount=0;_finddata_t fileInfo;long handle = _findfirst(fileName, &fileInfo);if (handle == -1L){cerr << "failed to transfer files" << endl;return false;}do {fileCount++;}while (_findnext(handle, &fileInfo) == 0);cout<<"================================================"<<endl;cout<<"there are "<<fileCount<<" images in "<<fpath<<endl;cout<<"================================================"<<endl;

2. 遍历包括子文件夹的文件，fileType为类似于“.jpg”，如果要查找全部文件则fileType为空或者“*”

void findFileInFolder(string folderPath,string fileType){_finddata_t FileInfo;string strfind = folderPath + "\\*" + fileType;long Handle = _findfirst(strfind.c_str(), &FileInfo);if (Handle == -1L){cerr << "can not match the folder path" << endl;exit(-1);}do{//判断是否为子目录if (FileInfo.attrib & _A_SUBDIR)    {//忽略当前和父文件夹（"." 和 ".."）if( (strcmp(FileInfo.name,".") != 0 ) &&(strcmp(FileInfo.name,"..") != 0))   {string newPath = folderPath + "\\" + FileInfo.name;findFileInFolder(newPath,fileType);}}else  {cout << folderPath << "\\" << FileInfo.name  << "\n";}}while (_findnext(Handle, &FileInfo) == 0);_findclose(Handle);}
