How can I use C# to sort values numerically?

Question

I have a string that contains numbers separated by periods. When I sort it appears like this since it is a string: (ascii char order)

3.9.5.2.1.1
3.9.5.2.1.10
3.         


        

Answer 1

You can use the awesome AlphanumComparator Alphanum natural sort algorithm by David Koelle.

Code:

OrderBy(o => o.MyString, new AlphanumComparator())

If you're gonna use the C# version change it to:

AlphanumComparator : IComparer

and

public int Compare(string x, string y)
