How do I create a class with an array within it?

I'm trying to create a class for people with an array of hobbies within it, but cannot figure out how to do that, can anyone tell me how I can go about doing this? internal class person { public string name { get; set; } public int age { get; set; } public int numberOfHobbies { get; set; } //how do I do an array? //public string[numberOfHobbies] hobbies { get; set; } }

public string[] Hobbies { get; set; }

I'm getting an error after myContacts.Add(new person { name = "Ian", age = 27, numberOfHobbies = 3, hobbies = { "basketball", "Soccer", "Golf"} }); the errors are the "basketball", "Soccer", "Golf" part

var person = new Person()
{
    Hobbies = new[] { "derp" }
};

var person = new Person()
{
    Hobbies = new[] { "derp" }
};

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; } // date of birth instead?
    public int NumberOfHobbies => Hobbies.Length;
    public string[] Hobbies { get; set; }
}

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; } // date of birth instead?
    public int NumberOfHobbies => Hobbies.Length;
    public string[] Hobbies { get; set; }
}
