Get-Only Properties

A get-only property can be assigned in a constructor and read afterward.

GetOnlyProperties.cs

using System;

class Badge
{
    public string Label { get; }
    public int Level { get; }

    public Badge(string label, int level)
    {
        Label = label;
        Level = level;
    }
}

class Program
{
    static void Main()
    {
        int level = ;
        Badge badge = new Badge("helper", level);
        string summary = badge.Label + ":" + badge.Level;

        Console.WriteLine($"level={level}");
        Console.WriteLine($"summary={summary}");
    }
}

using System;

class Badge
{
    public string Label { get; }
    public int Level { get; }

    public Badge(string label, int level)
    {
        Label = label;
        Level = level;
    }
}

class Program
{
    static void Main()
    {
        int level = ;
        Badge badge = new Badge("helper", level);
        string summary = badge.Label + ":" + badge.Level;

        Console.WriteLine($"level={level}");
        Console.WriteLine($"summary={summary}");
    }
}

using System;

class Badge
{
    public string Label { get; }
    public int Level { get; }

    public Badge(string label, int level)
    {
        Label = label;
        Level = level;
    }
}

class Program
{
    static void Main()
    {
        int level = ;
        Badge badge = new Badge("helper", level);
        string summary = badge.Label + ":" + badge.Level;

        Console.WriteLine($"level={level}");
        Console.WriteLine($"summary={summary}");
    }
}
