Creating a New Class with Collection Initializers in C# [duplicate]

Question

I have a class that I created. I would like to allow the class to be able to have a collection initializer. Here is an example of the class:

public class Cat
{
    private Dictionary catNameAndType = new Dictionary();

    public Cat()
    {

    }

    public void Add(string catName, string catType)
    {
        catNameAndType.Add(catName,catType);
    }

}

I would like to be able to do something like this with the class:

Cat cat = new Cat()
{
    {"Paul","Black"},
    {"Simon,"Red"}
}

Is this possible to do with classes that are not Dictionaries and Lists?

Answer 1

In addition to an Add method, the class must also implement the IEnumerable interface.
