Find and replace Asterisk (*) from a string using Regex

Question

I have a string like this:

Durham * versus Yorkshire

and I have used a regex in C# to replace that asterisk in the string with some text, as:

string aString = "Durham * versus Yorkshire";
string newstring = Regex.Replace( aString, @"\*", "Replaced text");

I want this output:

Durham Replaced Text versus Yorkshire

but this is not working. I thought that escaping the * with a \ will find it. But its not. You can test it here as well: RegExr. Can somebody tell me where am I wrong?

Please put what you did in regex101.com. Do ctrl-s or command-s and share the link with us here. — sshashank124, May 06 '14 at 07:30
Seems to be working just fine for me, [Image](http://i.gyazo.com/781dbfdc86029c055a812bb3093d0e7c.png) — Prime, May 06 '14 at 07:31
why Regex for such a simple thing? `string newstring = aString .Replace("*", "Replaced text")` — Milan Halada, May 06 '14 at 07:32
@HamletHakobyan - I need to this using regex for some reasons. — Preetesh, May 06 '14 at 07:33
@Uriel_SVK I have put just a sample here. There is more to do. But the regex is not finding `*` anyway. — Preetesh, May 06 '14 at 07:34
Your code seems to be working for everybody else. Can you show how you check the output? Also, if you *have* to use regex please update your example/explain more: as it is now you don't need them. — Robin, May 06 '14 at 07:39

For a simple replace like this one you don't need to use regex, String.Replace will be enough:

string aString = "Durham * versus Yorkshire";
string newstring = aString.Replace("*", "Replaced text");

Tried your code and it seemed to work. Even your regex works on regexr.com

string aString = "Durham * versus * Yorkshire";
string newstring = Regex.Replace(aString, @"\*", "Replaced text");

Output

Durham Replaced text versus Replaced text Yorkshire

You could also consider using String.Replace() like

aString.Replace("*", "Replaced text");
