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

It's been a while and I needed a similar answer for handling password validation. Pretty much what VITA said, but here was my specific take for others needing it for the same thing:

var pwdSpecialCharacterCount = Regex.Matches(item, "[~!@#$%^&*()_+{}:\"<>?]").Count;
var pwdMinNumericalCharacters = Regex.Matches(item, "[0-9]").Count;
var pwdMinUpperCaseCharacters = Regex.Matches(item, "[A-Z]").Count;
var pwdMinLowerCaseCharacters = Regex.Matches(item, "[a-z]").Count;
