Auto-Implemented Properties

Declare properties with concise auto syntax.

What Is a Property?

A property looks like a field from the outside but is backed by accessor methods (get and set). Properties let you expose data while keeping control over how it is read and written.

using System;

class Program
{
    public string Name { get; set; }

    static void Main()
    {
        var p = new Program();
        p.Name = "Coddy";
        Console.WriteLine(p.Name);
    }
}

Auto-Implemented Syntax

An auto-implemented property uses { get; set; }. The compiler generates a hidden backing field for you, so you do not write one by hand.

using System;

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

class Program
{
    static void Main()
    {
        var person = new Person { FirstName = "Ada", Age = 36 };
        Console.WriteLine(person.FirstName + " is " + person.Age);
    }
}
