Replace all non Alpha Numeric characters, New Lines, and multiple White Space with one Space

Question

I\'m looking for a neat RegEx solution to replace

• All non Alpha-Numeric Characters
• All NewLines
• All multiple instances of white space

Answer 1

For anyone still strugging (like me...) after the above more expert replies, this works in Visual Studio 2019:

outputString = Regex.Replace(inputString, @"\W", "_");

Remember to add

using System.Text.RegularExpressions;
