What are classes in PowerShell?

In PowerShell, a class is a template for creating objects.

It defines the properties and methods of the object, and it provides a blueprint for how the object will behave. Cla`sses allow you to create objects that share common properties and behavior, and they allow you to reuse and extend your code.

Example

Here's an example of a class in PowerShell:

class Person {
    [string]$FirstName
    [string]$LastName

    Person([string]$First, [string]$Last) {
        $this.FirstName = $First
        $this.LastName = $Last
    }

    [string]ToString() {
        return "$($this.FirstName) $($this.LastName)"
    }
}

In this example, the Person class is defined with two properties, FirstName and LastName, which are both strings.

The Person class also has a constructor, which is a special method that is used to initialize the object. The constructor takes two string arguments, $First and $Last, which are used to initialize the FirstName and LastName properties of the object.

The Person class also has a ToString() method, which is a special method that is called when the object is converted to a string. This method returns a string with the FirstName and LastName properties concatenated together with a space between them.

To create an object from the Person class, you can use the New-Object cmdlet. Here's an example:

$person = New-Object Person -ArgumentList "John", "Doe"
Write-Output $person

In this example, the New-Object cmdlet is used to create an object from the Person class.

The -ArgumentList parameter is used to specify the arguments that will be passed to the constructor, which are "John" and "Doe" in this example. The code will output a string with the FirstName and LastName properties concatenated

Conclusion

In PowerShell, a class is a template for creating objects.
