Order filenames by number

I have been working on a c# image viewer that will read images from my computer and show them in the program.

//foreach file in path display the filename

foreach (var filename in Directory.GetFiles(<path>))
{
    MessageBox.show(filename);
}

//Get image by number

var image = Directory.GetFiles(<path>).elementatordefault(<picnumber>).tostring());

My problem is that even if my images are ranked in order in the folder: 1,2,3,4 .....12,13,14....101,102, my application will show the files in the following order: 1,101,102,12,13,2...

How would I show the images in the correct like they are in the folder of the pc? I can't believe I would need to add each file to an array or list and then preform a sorting algorithm... (I would also need to split the file path and extension)there must be a simpler way of doing this,any help would be much appreciated.

I finally got round too working out how to sort files in a "natural order" perhaps someone will find this code useful as too how I did it.

        List<string> mylist = new List<string> { };
        foreach (var f in Directory.GetFiles(FilePath1))
        {
            mylist.Add(f);
        }

        var result = mylist.OrderBy(x => x.Length);

You need to sort and implement your own comparer, if you know the format of the file names. This thread might help you : Sorting mixed numbers and strings
