Folder search in combo box C# WPF

Question

I am trying to search folder, those are placed in my local drive by using ComboBox just like Google suggestions. All goes well but by default it searches .sys files. I am wondering is there any extension of folder is available ? .

Or any other idea to search whole folder in combo box by using C# WPF ?

 public FileInfo[] MyCollection { get; set; }

    public MainWindow()
    {
        try
        {                
            var di = new DirectoryInfo("c:\\");
            MyCollection = di.GetFiles();
            InitializeComponent();
            DataContext = this;
        }
        catch(Exception e)
        {
            MessageBox.Show(e.Message);
        }
    }

Answer 1

There are a few things that you will need to change then

Change your collection to

public DirectoryInfo[] MyCollection { get; set; }

and then the fetch to

MyCollection = di.GetDirectories();

This will give you a list of folders (or directories) instead of the list of files.
