How to replace all non-valid characters in string?

How would I go about in replacing every character in a string which are not the following: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_.@-

with -

So for example, the name Danny D'vito would become DannyD-vito

My inital thought was converting string to char[] and looping through and checking each character, then convert back to string. But my hunch is telling me there must be an easier way to do this

Regex.Replace() approach

string input = "Danny D'vito";
string result = new Regex("[^a-zA-Z0-9_.@-]").Replace(input, "-");
