Remove Special Chars from string using C#

Hello everyone, I am sharing  the code to remove special characters from  string using the ASP.Net C#.

private static string RemoveSpecialChars(string str)

 {

     string[] chars = new string[]{ ",", ".", "/", "!", "@", "#", "$", "%", "^", "&",                                       "*", "'", "\"", ";", "_", "(", ")", ":", "|", "[", "]" };

       for (int i = 0; i < chars.Length; i++)

        {

             if (str.Contains(chars[i]))

                {

                    str = str.Replace(chars[i], "");

                }

         }

  char[] arr = str.Where(c =>(char.IsLetterOrDigit(c) || char.IsWhiteSpace(c) || c == '-')).ToArray();

   str = new string(arr);

   return str;

 }
