string.format - Commas as decimal separator

Given the input 123.45, I'm trying to get the output 123,45 via String.Format.

Because of the system I'm working in, the actual format strings (e.g. {0:0.00}) are saved in a config file and transformed later down the pipeline.

Editing the config file to add a new format is "safe" and I can get this through quite quickly. Editing the actual parser later down the line is "risky" so will need a more significant QA resource and I need to avoid this.

As a result, some caveats:

So can it be done?
Is there any format I can pass to string.Format which will transform 123.45 into 123,45?

Just for the fun of it :)

        double value =123.45;
        Console.WriteLine(String.Format("{0:#0.00}\b\b\b,", value));

This of course only works when there is a cursor, like in the console, otherwise the backspace control characters have no effect.

Sorry, but i can't think of a real way in accomplishing this.

If you can you multiply the input by 100 then the following should work:

double input = 123.45;
string pattern = "{0:###\\,##}";

var result = String.Format(pattern, input*100);
