C++最简单遍历文件夹

话不多说，直接上代码：

#include 
#include 
#include 
using namespace std;

std::vector<std::string>readFolder(const std::string &image_path)
{
    std::vector<std::string> image_names;
    auto dir = opendir(image_path.c_str());

    if ((dir) != nullptr)
    {
        struct dirent *entry;
        entry = readdir(dir);
        while (entry)
        {
            auto temp = image_path + "/" + entry->d_name;
            if (strcmp(entry->d_name, "") == 0 || strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0)
            {
                entry = readdir(dir);
                continue;
            }
            image_names.push_back(temp);
            entry = readdir(dir);
        }
    }
    return image_names;
}


int main()
{
	# 得到所有文件路径
    auto ss = readFolder("./res");
   
    for (const auto& i:ss)
    {
        cv::Mat src_img = cv::imread(i);
    }
    
    return 0;
}
