本文介绍了一个使用C#编写的函数，该函数能够获取指定路径下所有文件及文件夹的图标，并将其显示在ListView中。文章展示了如何利用Win32 API来获取文件和文件夹的图标资源。

public void GetListViewItem(string path, ImageList imglist, ListView lv)//获取指定路径下所有文件及其图标
        {
            lv.Items.Clear();
            Win32.SHFILEINFO shfi = new Win32.SHFILEINFO();

            {
                string[] dirs = Directory.GetDirectories(path);
                string[] files = Directory.GetFiles(path);
                for (int i = 0; i < dirs.Length; i++)
                {
                    string[] info = new string[4];
                    DirectoryInfo dir = new DirectoryInfo(dirs[i]);
                    if (dir.Name == "RECYCLER" || dir.Name == "RECYCLED" || dir.Name == "Recycled" || dir.Name == "System Volume Information")
