What is the name of the method Apple.IPhone.Dialer.Dial(string phoneNumber);

What is the name of the method Apple.IPhone.Dialer.Dial(string phoneNumber);

I have tried phoneNumber and string phoneNumber and (string phoneNumber) But none of that works. From the video I learn that you go from right to left. And method is the first on the right.

Example.

StackOverflow.Controllers.CommentController.Details();

CommentControllers is the string, because it's like

Namespace, Class, Method

Things to keep in mind when identifying parts of method names are:

  • The general rule for method names is: namespace.class.method()
  • Only the namespace can contain periods (.)
  • The last two periods separate the namespace from the class and the class from the method
  • Any other periods are part of the namespace.

So the word closest to the parentheses is the method, the word to the left of it is the class, and everything left of that is the namespace. For example, if you had this:

System.IO.File.Copy(Parameters...);

The method is Copy, the class is File, and the namespace is System.IO.

Hint: "(string phoneNumber)" is a parameter you are passing into the method, not the name of the method itself.
