c++递归访问目录下所有文件

#include <dirent.h> #include <iostream> #include <cstdlib> #include <cstring> using namespace std; void GetFileInDir(string dirName) { DIR* Dir = NULL; struct dirent* file = NULL; if (dirName[dirName.size()-1] != '/') { dirName += "/"; } if ((Dir = opendir(dirName.c_str())) == NULL) { cerr << "Can't open Directory" << endl; exit(1); } while (file = readdir(Dir)) { //if the file is a normal file if (file->d_type == DT_REG) { cout << dirName + file->d_name << endl; } //if the file is a directory else if (file->d_type == DT_DIR && strcmp(file->d_name, ".") != 0 && strcmp(file->d_name, "..") != 0) { GetFileInDir(dirName + file->d_name); } } } int main(int argc, char* argv[]) { if (argc < 2) { cerr << "Need Directory" << endl; exit(1); } string dir = argv[1]; GetFileInDir(dir); }
