Regular Expression Replace should do the trick

contact.name = Regex.Replace(contact.name, @"[\(\)\- ]", String.Empty);

Using LINQ:

var s = "abcd 238(23)2342-23";
var exclusion = "()- ";

var result = new string(s.ToCharArray().Where (x => !exclusion.Contains(x)).ToArray());

or

var s = "abcd 238(23)2342-23";

var result = new string(s.ToCharArray().Where (x => !"()- ".Contains(x)).ToArray());

StringBuilder will be more effecient if you're doing more than a few replacements.
