How to format a string with 1000s separator and zeros after comma in C#

Question

I want to format a string with 1000's separator and also two decimal places by default

I tried this one but it's not working as it fails to append two zeros when there are no decimals

String.Format("{0:#,##0.##}", money); //I want something like 1000.23 and also 1000.00

You've already used 0 as a placeholder in your string. Why don't you use it for decimals too? — Panagiotis Kanavos

Just to be sure you're not making this more complicated then necessary

String.Format("{0:f2}", money);

Maybe standard number format is enough and custom number format is not needed. But as mentioned if your Culture has a , as seperator, this won't work.

You should also include CultureInfo in the call to be sure.

@kiziu which CultureInfo? The application's locale will be used by default. Typically, that's the correct option when formatting for display. InvariantCulture is used when the string is used for storage or communicating with other programs

@PanagiotisKanavos, The one that will correctly present the value according to the requirements. Nowhere does the OP say if the application locale will format the value correctly. That is why I did not specify which CultureInfo, only that one should be provided to ensure correct formatting.
