Extract multiple integers from string and store as int

Question

I know that this will extract the number and store as int -

string inputData = \"sometex10\";

string  data = System.Text.RegularExpressions.Regex.Match(inputDa         


        

Answer 1

C# program that uses Regex.Split

Referencing : http://www.dotnetperls.com/regex-split

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
    //
    // String containing numbers.
    //
    string sentence = "10 cats, 20 dogs, 40 fish and 1 programmer.";
    //
    // Get all digit sequence as strings.
    //
    string[] digits = Regex.Split(sentence, @"\D+");
    //
    // Now we have each number string.
    //
    foreach (string value in digits)
    {
        //
        // Parse the value to get the number.
        //
        int number;
        if (int.TryParse(value, out number))
        {
             Console.WriteLine(number);
        }
    }
    }
}

Answer 2

You can use a LINQ one-liner:

var numbers = Regex.Matches(inputData, @"\d+").Select(m => int.Parse(m.Value)).ToList();

Or use ToArray() if you prefer an array instead of a list.

Answer 3

You can use something like this:

string inputData = "sometex10";
List<int> numbers = new List<int>();
foreach(Match m in Regex.Matches(inputData, @"\d+"))
{
    numbers.Add(Convert.ToInt32(m.Value));
}

This will store the integers in the list numbers
