[Solved] Need help and a concise explanation for updating an existing constructor in C#

by


Modify the constructor by adding one extra parameter dateOfBirth. Use this parameter to initialize your property DateOfBirth. This way, the Person can never be instantiated without a valid value for DateOfBirth.

public Person(string firstName, string lastName, DateTime dateOfBirth)
{
    FirstName = firstName;
    LastName = lastName;
    DateOfBirth = dateOfBirth;
}

now you can construct it like this:

Person p = new Person("John", "Smith", new DateTime(2010, 01, 13));
