Question

what are the advantages of calling one constructor by other if there are multiple constructors?
Thanks

Answer 1

the same advantages you get when you do method overloading : you don’t repeat the same code

public class Person
{
    public Person(string name,string lastName )
    {
        Name = name;
        LastName = lastName;
    }

    public Person(string name, string lastName,string address):this(name,lastName)
    {
        //you don't need to set again Name and Last Name
        //as you can call the other constructor that does the job
        Address = Address;
    }
    public string Name { get; set; }
    public string LastName { get; set; }
    public string Address { get; set; }
}
