    removing special characters from string

    Trying to strip all special characters from a string by using the following:

    using System.Text.RegularExpressions;

string your_String = CurrentPage.description;
string my_String =  Regex.Replace(your_String, @"[^0-9a-zA-Z]+", ",");

    unfortunately I get the following error:

    The best overloaded method match for system.text.regularexpresions.regex.replace(string,string)' has some invalid arguments. Any suggestions?

    Hi Jeff

    It's because you're passing 3 parameters but the the method only accepts two as the error message is also indicating.

    You can see some examples on how to use Regex.Replace here https://msdn.microsoft.com/en-us/library/xwewhkd1%28v=vs.110%29.aspx

    You should be able to do something like

      string pattern =  @"[^0-9a-zA-Z]+";
  string input = CurrentPage.description;
  string replacement = "";
  Regex rgx = new Regex(pattern);
  string result = rgx.Replace(input, replacement)

 //Write out the result
@result

    Hope this helps.

    Thanks Jan

    This is what I ended up using for anyone else that would need this. 

       string pattern = @"[^\w\.@:-]";
   string input = Umbraco.StripHtml(CurrentPage.description).ToString();

   string replacement = " ";
   Regex rgx = new Regex(pattern);
   string result = rgx.Replace(input, replacement);
