String.Format() to add commas in thousands place for a number not working

Question

String.Format to add commas in thousands place just add space without comma.

I tried:

 var total = string.Format("{0:n0}", 12345);
 // expect: total = 12,345
 // actual: total = 12 345

Anything I'm missing?

You missed updating your SO profile so we can tell where you live. The exact formatting is culture-specific and can be overridden with Control Panel. Consider using CultureInfo.InvariantCulture.NumberFormat if you insist on commas. — Hans Passant, Jun 05 '17 at 09:57

This is a culture thing. In your locale, space is the thousands specifier, apparently. I see commas. To see a specific locale's output, specify that explicitly. A very common option is "invariant":

var total = string.Format(CultureInfo.InvariantCulture, "{0:n0}", 12345);
