How to get the count of only special character in a string using Regex?

Question

If my input string is ~!@#$%^&*()_+{}:\"<>?

How do I get the count of each special character using Regex? For example:

Regex.Match         


        

Answer 1

The non-regex way (which sounds much easier) it to make a list of characters you want to check and use Linq to find the count of those characters.

string inputString = "asdf1!%jkl(!*";

List charsToCheckFor = new List() { '!', '@', '#', ..... };

int charCount = inputString.Count(x => charsToCheckFor.Contains(x));

I am making you write in all the characters you need to check for, because you need to figure out what you want.
