Instance: Making a Class Auto (Automotive) in PowerShell
The next instance exhibits methods to create a easy PowerShell class and instantiate an object from it.
class Auto {
[string]$Marke
[string]$Modell
[int]$Baujahr
[int]$Leistung
[int]$Hubraum
[int]$Kilometerstand
[int]$Preis
[void] Starten() {
Write-Host "Das Auto startet."
}
}
# Present courses and members (attributes + strategies)
[Auto] | Get-Member -MemberType Property
[Auto].DeclaredMembers | The place-Object { $_.MemberType -eq "Property" }
# Create a Automotive class object
$auto1 = New-Object Auto # oder $auto1 = [Auto]::new()
$auto1.Marke = "BMW"
$auto1.Modell = "X5"
$auto1.Baujahr = 2018
$auto1.Leistung = 200
$auto1.Hubraum = 2000
$auto1.Kilometerstand = 10000
$auto1.Preis = 50000
$auto2 = [Auto]::new()
$auto2.Marke = "Audi"
$auto2.Modell = "Q7"
$auto2.Baujahr = 2019
$auto2.Leistung = 250
$auto2.Hubraum = 2500
$auto2.Kilometerstand = 5000
$auto2.Preis = 60000
$auto1
$auto1 | Get-Member
$auto1 | Get-Member -Title Marke
$auto1.GetType()
$auto1 | Choose-Object -Property Marke
# Enhance the value of the BMW X5 by 10%.
$auto1.Preis = $auto1.Preis * 1.1
$auto1.Preis
# Auto1 starten
$auto1.Starten()
# Present Auto1 and Auto2
$autos = @($auto1, $auto2)
$autos | Format-Desk -Property Marke, Modell, Baujahr, Preis
# Different:
$autos | Choose-Object -Property Marke, Modell, Baujahr, Preis
