Properties

Relax. We'll talk through this in plain words — no textbook voice.

Properties are used to safely access private data. Instead of making a field directly public, you control access through get / set, which also makes it easy to add validation logic.

csharp

class Person
{
    private string name;

    public string Name
    {
        get { return name; }
        set
        {
            if (!string.IsNullOrWhiteSpace(value))
            {
                name = value;
            }
        }
    }
}

class Program
{
    static void Main(string[] args)
    {
        Person person = new Person();
        person.Name = "Liam";
        Console.WriteLine(person.Name);
    }
}

What to take away from this code

name field is private, so it can't be changed directly from outside the class.
Name property controls and provides access to that data.
set checks against an empty string being set.
