How to use string.Endswith to test for multiple endings?

Question

I need to check in string.Endswith(\"\") from any of the following operators: +,-,*,/

If I have 20 operators I don\'t want to use ||<

Answer 1

How about:-

string input = .....;
string[] matches = { ...... whatever ...... };

foreach (string match in matches)
{
    if (input.EndsWith(match))
        return true;
}

I know it is dreadfully old school to avoid LINQ in this context, but one day you will need to read this code. I am absolutely sure that LINQ has its uses (maybe i'll find them one day) but i am quite sure it is not meant to replace the four lines of code above.
