How to create a array with identifiers [duplicate]

Question

I want to create an array with identifiers To be more clear

Jack  Karen Tom Example Person
30    40    50  Age

Like this It does not be array necessarily but ı must search the age with name Using database is not fine for me, the age and name is just the simplification of my problem Thanks

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. I suggest reading How do I ask a Good Question and Writing the Perfect Question. Also, be sure to take the tour (you get a badge!). — Igor

Create a class Person and add instances of it in a collection like a List<Person>. You can find a person for exampe with LINQ: Person jack = allPersons.FirstOrDefault(p => p.Name == "Jack"); — Tim Schmelter

A very simple implementation could use a Dictionary like this:

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        Dictionary<string, int> values = new Dictionary<string, int>
        {
            { "Jack", 30 },
            { "Karen", 40 },
            { "Tom", 50 },
        };
        
        Console.WriteLine(values["Jack"]);
    }
}

If you want to store more complex values, you can use a C# class:

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

You can then create instances of this class and use them:

var person = new Person { Name = "Jack", Age = 30 };
