Create Classes, Objects and JSON Files
A PowerShell tutorial by Peter Kalmstrom
 With
Windows PowerShell you can automate many tedious administration
tasks, so PowerShell is a very useful tool for IT professionals.
In the demo below Peter Kalmstrom, CEO of kalmstrom.com
Business Solutions, shows how to use PowerShell to create
classes, objects and JSON files.
In computing, a shell is a user interface that gives access
to services in an operating system, thus the name PowerShell.
The user interface resembles the command prompt, but PowerShell
gives many more options.
Windows PowerShell is included Windows, so anyone can try
it. The demo below is however intended for people who already
know some about object oriented programming or computer
science.
Class and object
To understand how Peter's simple example can be built out
and used for more advanced processes, it is important that
you understand the difference between a class and an object:
- A class is written by a programmer. The class describes
an object and tells how the object can be manipulated.
- An object is the computer's representation of the
class, and it exists when the program is run.
Steps
In the demo below Peter uses a classical "car" example to
show how to do the following in PowerShell:
- Define a class "Car", and set its properties.
- Create an object "My Car" based on the class "Car"
and set its property values.
- Run the script. This is done by selecting what should
be run and pressing F8.
- Check the object's property values.
- Convert the object to a JSON file and add it to
a directory.
Do you need assistance in creating a PowerShell script that
performs complicated operations quickly and correctly?
