Question

Example: I want to find 1234 in a string named target:

string target = "55555>>><<[1234]<>>>788";

How can I find the number between [,] without knowing how much digits between [], before[ or after ]? I need a small code for my project.

Thanks.

This sounds like a job for regular expressions

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "55555>>><<[1234]<>>>788";

            Regex r = new Regex(@"\[(\d*)\]");
            Match match = r.Match(str);
            Console.WriteLine(match.Groups[1].Value);
        }
    }
}

the above code has the following output

1234
