C++17 filesystem, Regex traversal Directory

C++17 FS is still pretty good.

#include<filesystem>#include<regex>  //正则表达式namespace fs = std::experimental::filesystem;int main（）{    string strPath = "D:\\pic\\new";    regex fileSuffix("(.*)(.jpg)");// *.jpg, *.png      //regex fileSuffix("(.*).(.jpg)"); 也行    //regex fileSuffix(".*z.*\\.(jpg|png)");//包含字母z的所有jpg或png图片    for (auto&DirectoryIter : fs::directory_iterator(strPath))    {        auto filepath = DirectoryIter.path();        auto filename = filepath.filename();    if (std::regex_match(filename.string(), fileSuffix))    {        vecFilePath.push_back(filepath.string());        cout << filepath << endl;    }    //replace_extension替换扩展名    //stem去掉扩展名    }}
