I would do differently on a light C# example from http://www.trelford.com/blog/post/LighterCSharp.aspx

ReadonlyProperties.cs

public class Person {
    public Person(string name, int age)    {
        _name = name;
        _age = age;    
    }
    private readonly string _name;
    private readonly int _age;
    /// Full name
    public string Name { get _name; }
    /// Age in years   
    public int Age { get _age; }
}

/// In C# 6.0 you can do

public class Person {
    public Person(string name, int age) {
        Name = name;
        Age = age;    
    }
    /// Full name
    public string Name { get; } // private setter implied on this auto-property   
    /// Age in years   
    public int Age { get; }
}
