You Can Define Multiple Constructors

We can define multiple constructors in a class,  each one taking a different set of parameters.
Here’s an example where we define four different constructors for a Dog object.

public string Name { get; set; }
public int Age { get; set; }
public string Motto { get; set; }
 
public Dog(string name)
{
    Name = name;
    Age = 1;
    Motto = "Happy";
}
 
public Dog(string name, int age)
{
    Name = name;
    Age = age;
    Motto = "Happy";
}
 
public Dog(string name, string motto)
{
    Name = name;
    Motto = motto;
    Age = 1;
}
 
public Dog(string name, int age, string motto)
{
    Name = name;
    Age = age;
    Motto = motto;
}
We now have four different ways to construct a Dog object.

Dog d1 = new Dog("Kirby");                        // name
Dog d2 = new Dog("Jack", 16);                     // name, age
Dog d3 = new Dog("Ruby", "Look out window");      // name, motto
Dog d4 = new Dog("Lassie", 71, "Rescue people");  // name, age, motto
