RegEx to replace special characters in a string with space ? asp.net c#

Question

string inputString = "1/10 EP Sp'arrowha?wk XT R;TR 2.4GHz Red";
//Characters Collection: (';', '\', '/', ':', '*', '?', ' " ', '<', '>', '|', '&', ''')
string outputString = "1 10 EP Sp arrowha wk XT R TR 2.4GHz Red";

Answer 1

Full disclosure regarding the following code:

• It's not tested
• I probably messed up the character escaping in new Regex(...);

• I don't actually know C#, but I can Google for "C# string replace regex" and land on MSDN

  Regex re = new Regex("[;\\/:*?\"<>|&']");
  string outputString = re.Replace(inputString, " ");

Here's the correct code:

string inputString = "1/10 EP Sp'arrowha?wk XT R;TR 2.4GHz R\\ed";
Regex re = new Regex("[;\\\\/:*?\"<>|&']");
string outputString = re.Replace(inputString, " ");
// outputString is "1 10 EP Sp arrowha wk XT R TR 2.4GHz R ed"
