Question

I have strings and I need to make doubles from them. They’re all in format:

"Blabla 11/moreBla 17-18"  That should become 11.1718
"Blabla 7/moreBla 8-9" --> 7.89
"Blabla 4/moreBla 6-8" --> 4.68

etc.

There could also be extra spaces or dash could be a forward slash. So, anything like that:

"Blabla 11/moreBla 17-18"
"Blabla 11 / moreBla 17-18"
"Blabla 11/moreBla 17/18"
"Blabla 11/moreBla 17 / 18"
"Blabla 11 / moreBla 17 / 18"

I tried splitting the string first, but then apparently there are all these other cases. So split isn’t working well here. Maybe RegEx could be of help?

Code:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        string input = "Blabla 11/moreBla 17-18";
        string[] s = input.Split('/');
        Console.WriteLine(Regex.Replace(s[0], @"[^\d]", "") + "." + Regex.Replace(s[1], @"[^\d]", "")); 
    }
}

Output:

11.1718

Or this code:

 using System;
 using System.Text.RegularExpressions;

 class Program
 {
     static void Main()
     {
         string input = "Blabla 11/moreBla 17-18";
         string[] s = Regex.Replace(input, @"[^\d\/]", "").Split('/');
         Console.WriteLine(s[0] + "." + s[1]);
     }
 }

Output:

11.1718
