I have the following number: 4.3

I'd like to display this number as 4,3 for some of our European friends.

I was under the impression that the following line would do the trick:

string ret = string.Format("{0:0,0}", 4.3); // returns "04", not "4,3"

Am I using the incorrect string?

I think:

string.Format(System.Globalization.CultureInfo.GetCultureInfo("de-DE"), "{0:0.0}", 4.3);

should do what you want.
