This might be your answer - Formatting Numbers as Strings with Commas in place of Decimals

The top answer there is:

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

Decimal representation is completely depends on culture. So you need to provide appropriate culture during convertion, like in code below:

        double test = 8888.33;
        MessageBox.Show(string.Format(System.Globalization.CultureInfo.GetCultureInfo("EN-US"),"{0:0,0.0}",test));
