Solution 1

WPF has nothing to do with the file system. Your question is a C# question. In the System.IO namespace is a Directory class, it has static GetFiles and GetDirectories methods, which you can use to recurse through the file system

i see, if use GetFiles and GetDirectory need to use foreach loop??

I didn't say anything about a loop. I said you can recurse if you want to go through several levels.

if want to list out all files and folder inside D:\testfol\test1
but folder selected path is D:\testfol is it possible??
DirectoryInfo di = new DirectoryInfo(@fol.SelectedPath);
FileInfo[] fi = di.GetFiles();
foreach (FileInfo f in fi)
{
if (f.Attributes.ToString().Contains(FileAttributes.Hidden.ToString()))
{
listresult.Items.Add(f.FullName);
}
}
foreach(DirectoryInfo d in di.GetDirectories())
if (d.Attributes.ToString().Contains("Hidden"))
{
listresult.Items.Add(d.FullName);
}

Yes, this is called 'recursion'. Search this site for articles on recursion, basically your method takes a path as a parameter and keeps calling itself as it goes down the tree.

Solution 2

You can use the code below

C#

foreach (System.IO.FileInfo fi in new System.IO.DirectoryInfo("D:\\testfol").GetFiles("*.*", System.IO.SearchOption.AllDirectories)
             {
// do something
             }
