I invite you to follow me on Twitter and Facebook. Windows PowerShell Classes Week will continue tomorrow when I will recap the class design and implementation. That is all there is to adding methods to a PowerShell 5.0 class. Here is the script and the associated calling of the methods: To call the accelerate method, I can use the same techniques: The second way to call the method is to call the New static method, and then call the method from that object:Ī third way to call the method uses New-Object, and it is what I call the "group and dot." This is shown here: The first way I can call my method, is to create an instance of the car (a new Car object), store the returned object in a variable, and then call the method. I run my script and I can test my methods. The complete class with the two new methods is shown here: Here is the method that accepts an input parameter: I do not have any error checking or parameter input validation, and so you should probably keep your speed less than 50 mph or so. This is determined by my speed supplied to the $arg variable. What the method is actually doing is starting at a relatively low beep, and increasing the frequency of the beep a certain number of times. I will then use this value to determine how fast my car will go. The input will be contained in the $arg variable. When I accelerate, I need to know how fast I am going, so I need to be able to pass a value to the method. The next method I want to add is the Accelerate method. When I call this method, it will sound a beep for a few seconds. The first method I will add is called the SoundHorn method.

I then use () to designate that it is a method, and I add my script block (surrounded by curly braces) that contains the code I want to call when I call the method. To add a method to the class, I simply go to the bottom of the class, and add the name of my method. For an example, and to have easier to read code, I am going back to the basic Car class (without the enums): The first method I want to add does not require any input parameters. If you need to review enums, you should read: Creating Instances of PowerShell 5 ClassesĪnother Note I talked about enums last week.

Note This is the fifth post in a series about creating classes in Windows PowerShell 5.0. I will conclude the post by showing three ways of calling the methods after they are implemented.

The point is to show you how to implement the methods. I am not adding any constraints or anything else. For the second method, I need to supply some information for the method to work. For the first method, I simply call it, and it works. There are two types of methods I am going to add. In Windows PowerShell classes, it is the methods that actually do something. I mean I can describe all I want, but what can I really do? It is sort of the difference between reading a literary novel where nothing happens and reading a thriller where every page contains action. It became very frustrating because in the end, it comes down to needing to actually do something. I could find the currently logged on user, but I could not log the user out…and so on. I could find the screen resolution, but I could not change the screen resolution.

I could easily find the name and the driver of the sound card, but I could not disable the sound card.
Although it was possible to glean lots of information, there were few things that actually did anything. I remember trying to teach VBScript and WMI in the old days. Having a bunch of properties, although cool, is in the end, rather unsatisfying. Microsoft Scripting Guy, Ed Wilson, is here.
