Question

I have a date with weeks using this format:

2012-15 - 2012-20

I want to format it to look like

2012 v15 - 2012 v20

How can this be done c#?

Answer 1

This should do the trick:

        String str = "2012-15 - 2012-20";
        String newStr = Regex.Replace(str, "(\\d+)-(\\d+)", "$1 v$2");
        Console.WriteLine(str);
        Console.WriteLine(newStr);
        Console.ReadLine();

Prints Out:

2012-15 – 2012-20

2012 v15 – 2012 v20
