How to use regexp for finding patterns in strings?

Question

I have many patterns that want to find matched string in many string arrays and replace them with \"NON\" string. for example, if we have:

str[0]={\"this\",\"is\         


        

Answer 1

A one liner just for fun :]

str = Array.ConvertAll(str, a => Array.ConvertAll(a, i => patterns.Contains(i) ? "NON" : i));
