Just use
只需使用
FileInfo[] info = dirInfo.GetFiles("*.*", SearchOption.AllDirectories);
which will handle the recursion for you.
它将为您处理递归。
回答by Dmitry Dovgopoly
You should recursivelyselect files from all subfolders.
您应该递归地从所有子文件夹中选择文件。
public void selectfolders(string filename)
{
FileInfo_Class fclass;
DirectoryInfo dirInfo = new DirectoryInfo(filename);
FileInfo[] info = dirInfo.GetFiles("*.*");
foreach (FileInfo f in info)
{
fclass = new FileInfo_Class();
fclass.Name = f.Name;
fclass.length = Convert.ToUInt32(f.Length);
fclass.DirectoryName = f.DirectoryName;
fclass.FullName = f.FullName;
fclass.Extension = f.Extension;
obcinfo.Add(fclass);
}
DirectoryInfo[] subDirectories = dirInfo.GetDirectories();
foreach(DirectoryInfo directory in subDirectories)
{
selectfolders(directory.FullName);
}
}
