Int custom ToString

Question

I would like to print out UInt32 as ##,##,##.
Comma every two digits.
Is there a way to do this?

ToString("N0");

Is a comma every three digits

You can do something like Regex.Replace(myUnit32.ToString(), ".{2}", "$0,") — Hakunamatata, Dec 01 '16 at 00:36
@active92 You can remove last comma if you change regex to .{2}(?!$) — Hakunamatata, Dec 01 '16 at 00:41

You should be able to use (with using System.Globalization;):

yourUInt.ToString("N0", new NumberFormatInfo { NumberGroupSizes = new[] { 2, }, })

Documentation: NumberGroupSizes property

Of course, this NumberGroupSizes property can also be set on the NumberFormat property of a CultureInfo (possibly obtained by cloning an existing read-only CultureInfo) which can then be assigned to System.Threading.Thread.CurrentThread.CurrentCulture.
