c# - Find all files in a folder

Question

I am looking to create a program that finds all files of a certain type on my desktop and places them into specific folders, for example, I would have all files with .txt into the Text folder.

Any ideas what the best way would be to accomplish this? Thanks.

I have tried this:

string startPath = @"%userprofile%/Desktop";
string[] oDirectories = Directory.GetDirectories(startPath, "");
Console.WriteLine(oDirectories.Length.ToString());

foreach (string oCurrent in oDirectories)
    Console.WriteLine(oCurrent);

Console.ReadLine();

It was not successful in finding all of the files.

A lot of these answers won't actually work, having tried them myself. Give this a go:

string filepath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
DirectoryInfo d = new DirectoryInfo(filepath);

foreach (var file in d.GetFiles("*.txt"))
{
      Directory.Move(file.FullName, filepath + "\TextFiles" + file.Name);
}

It will move all .txt files on the desktop to the folder TextFiles.
