C# RegEx for Numbers up to 100

Question

I created a regex to match numbers from 1-100, including decimals such as 50.25 For some reason, decimal numbers are not matching and I have no idea why. Can someone help? ``` string pattern = @"^([1-9][0-9]{0,1}(\.[\d]{1,2})?|100)$"; Regex r = new Regex(pattern); Match m = r.Match(s.SearchRadius); if (!m.Success) { s.SearchRadius = "20"; } ```

Accepted Answer

You're using the `@` sign on your string, so you shouldn't escape \ characters.

All you need is

```
string pattern = @"^([1-9][0-9]{0,1}(\.[\d]{1,2})?|100)$";
```
