#299 – Intellisense Shows You Available Constructors

If you have several different constructors define for a class or a struct, Intellisense in Visual Studio will show you the different constructors that you can use.

Assume that you have a Dog class, with two different constructors, as follows:

    public class Dog
        public string Name { get; set; }
        public int Age { get; set; }

        public Dog(string name, int age)
            Name = name;
            Age = age;

        public Dog(string name)
            : this(name, 1)

Because we have these two constructors, we can pass in either one or two parameters when using the new operator to construct a new instance of a Dog.

            Dog d1 = new Dog("Lassie");
            Dog d2 = new Dog("Django", 6);

Visual Studio will tell us, through Intellisense, that there are two constructors available.  Once the constructor signature pops up, you can use the arrow keys to cycle through the two options.
