You can instantiate each item of the array in one statement:
Person[] myPeople =
{
new Person("John", "Doe"),
new Person("Jane", "Doe")
};
I usually use this syntax whenever I know in advance the values of an
array that I'm creating.
One thing to note: Your line:
Person[] myPeople = new Person[5];
creates the array, but does not instantiate the objects in the array.
So when you call:
myPeople[0].firstName = "George";
it will throw a NullReferenceException because myPeople[0] has not
been instantiated yet.
