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

Given the complete lack of context, would this solution that is worse than using an easy || operator be of use:

Boolean check = false;
if (myString.EndsWith("+"))
     check = true;

if (!check && myString.EndsWith("-"))
     check = true;

if (!check && myString.EndsWith("/"))
     check = true;

etc.
