How to overload constructors with the "this" keyword
Just as you can use the "base" keyword to call constructors in inherited classes, you can use the "this" keyword to overload constructors in the same class.
using System;

namespace TestConstruct23843
{
    class Program
    {
        static void Main(string[] args)
        {
            Customer customer1 = new Customer("Joe", "Black");
            Customer customer2 = new Customer("Jim");

            Console.WriteLine("{0} {1}", customer1.FirstName, customer1.LastName);
            Console.WriteLine("{0} {1}", customer2.FirstName, customer2.LastName);
            Console.ReadLine();
        }
    }

    public class Customer
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

        public Customer(string firstName, string lastName)
        {
            FirstName = firstName;
            LastName = lastName;
        }

        public Customer(string firstName) : this(firstName, "(unknown)")
        { }
    }
}
Reed Copsey: There's no reason to use:

public Customer(string firstName) : this(firstName, "(unknown)")
        {
            FirstName = firstName;
        }

Why set FirstName 2x? Just use:

ublic Customer(string firstName) : this(firstName, "(unknown)")
        {
        }
Edward: Thanks, changed it.
need markup?
