c# - Regex remove special characters

Question

We need a C# function which will remove all special characters from a string.

Also, is it possible to change "George's" to "George" (remove both single quote and character s)?

Answer 1

This method will removed everything but letters, numbers and spaces. It will also remove any ' or " followed by the character s.

public static string RemoveSpecialCharacters(string input)
{
    Regex r = new Regex("(?:[^a-z0-9 ]|(?<=['"])s)", RegexOptions.IgnoreCase | RegexOptions.CultureInvariant | RegexOptions.Compiled);
    return r.Replace(input, String.Empty);
}
