Consider the following string:

```
Value >= 50000 && Value < 80000 && Code = 'AB'

```

I have to handle `5000`, `8000` and `SSCD`. how should I use regex? I used the following example, couldn't produce output.

```
var str = 'Value >= 50000 && Value < 80000 && Code = "AB"';
var m = Regex.Match(str, @"(\d+).(\d+).*?(\d+)");

```
