查找共享特殊文件夹（虚拟文件夹）中的所有文件

Question

Im looking for a way to find all files in an shared special folder (Virtual Folder). The Desktop for example is an shared folder, there is a public Desktop for all users and a private Desktop . By navigating with the file explorer to Desktop you will see the contents of both desktops merged together.

---

Example:

Shared folder for all:

dir C:\Users\Public\Desktop
Testfile1
Testfile2

Folder for the current user:

dir C:\Users\usera\Desktop
Testfile3
Testfile4

Now I want to get all files from Testfile1 till Testfile4 by looping trough C:\\Users\\usera\\Desktop

Someone has a clue howto get a list of the files of both directories merged together? Also not only for Desktop, there are other folders that behave the same way.

---

Pseudocode:

arrayDesktop = FunctionThatGetsAllFilesFrom(@"C:\Usera\Desktop");
foreach (var file in arrayDesktop)
{
    Console.WriteLine(file);
}

this should now print out

Testfile1
Testfile2
Testfile3
Testfile4

Answer 1

Use Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) and Environment.GetFolderPath(Environment.SpecialFolder.CommonDesktopDirectory) to get the files on your Desktop and the Public one respectively.

For other Virtual Folders you can look at the documentation . But you still have to merge all the files yourself.

This isn't tested code so forgive any errors, but it should be enough to get you started.

foreach (string dir in Directory.GetDirectories(@"c:\Users"))
{
    string fullDir = Path.Combine(dir, "Desktop");

    if (Directory.Exists(fullDir))
    {
        foreach (string file in Directory.GetFiles(fullDir))
        {
            Console.WriteLine(file);
        }
    }
}

Unless you're running this as an administrator though, you're likely to run into security issues ie unable to read the directory. In this instance, you're going to need the System.Net.NetworkCredential object and store the admin account in local cache - something like this.

NetworkCredential credential = new NetworkCredential(username, password, domain);
CredentialCache credentialCache = new CredentialCache();
credentialCache.Add(new Uri(@"\\computer-uri"), "Basic", credential);

They are separate folders on the file system. Windows just combines them both to display on the desktop. You are going to have to get all the files from both folders and combine them into a single list.

You can get the list of files in a given folder with Directory.GetFiles .

Once you have the files from both folders, you can combine them with the Linq Concat extension method.
