c# string.replace in foreach loop

Question

Somehow I can\'t seem to get string replacement within a foreach loop in C# to work. My code is as follows :

foreach (string s in names)
{
    s.Replace(\"pdf\"         


        

Answer 1

Why use replace, this will make the application slow. Use regex:
