Refactoring parameters

Now that we’ve explored the basics of methods and constructors, let’s talk about managing parameters. This is important because it is possible that poorly thought-out parameters can quickly reduce the maintainability of your code.

Let’s look at a few common refactorings you’ll want to perform over the life of your methods.

Reordering parameters

Sometimes, you’ll realize that the order of parameters in a method doesn’t make as much sense as another arrangement might. At other times, you might notice that a few of your methods take in the same kinds of parameters, but with inconsistent ordering. In either case, you’ll find yourself wanting to reorder your method parameters.

Let’s look at a practical example from the various MarkX methods we saw earlier:

FlightTracker.cs

public Flight? MarkFlightDelayed(string id,
  DateTime newDepartureTime) {
  // Details omitted...
