Question

I have a string like:

varA*varB%+Length('10%')

I want to replace all the “%” characters not within single quotes with “/100” to end up with

varA*varB/100+Length('10%')

Methinks this is a job for a RegEx?

Answer 1

non regex solution and not that dirty either 😉

    string a = "varA*varB%+Length('10%')";
    string[] b = a.Split('\'');
    string c = string.Empty;
    int i = 0;
    foreach (string sbs in b)
    {
        c += i%2==0?sbs.Replace("%","/100"):"'" + sbs + "'";//for the every odd value of i "%" is within single quotes
        i++;
    }
