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

Regex is not the best way to do this. here is the Linq based solution

string chars = "~!@#$%^&*()_+{}:\"<>?";
foreach (var item in chars.Where(x=> !char.IsLetterOrDigit(x)).GroupBy(x => x))
{
    Console.WriteLine(string.Format("{0},{1}",item.Key,item.Count()));
}

I understand that you need to count each spl character count. Correct me If am mistaken.
