I'm trying to change the data type of a variable in PowerShell from Boolean to String. Currently, I'm looping through an `$ArrayList` and attempting to set `$foo.Aktiv` to either "Aktiv" or "Inaktiv" based on its Boolean value. However, I keep getting an error that says the string was not recognized as a valid Boolean. Here's my current code snippet:
```powershell
foreach($foo in $ArrayList){
$bar = $foo.Aktiv
[string]$foo.Aktiv
$foo.Aktiv = $bar
if ($foo.Aktiv -eq "True"){
$foo.Aktiv = "Inaktiv"
}else{
$foo.Aktiv = "Aktiv"
}
}
```
Any ideas on how to resolve this issue?

It sounds like you're having trouble with the structure of your `$ArrayList`. Are you sure it's set up correctly? For testing, you could create a sample similar to this:
```powershell
$ArrayList = [PSCustomObject]@{ Aktiv = $true }, [PSCustomObject]@{ Aktiv = $false }
```
This could help you see if your conversion code runs without issues.
Also, make sure your `$ArrayList` is structured correctly. It could help to explore the contents with `$foo.GetType()` to ensure everything aligns as expected before you run your conversion logic.
If your goal is just to have 'Aktiv' or 'Inaktiv' displayed instead of the Boolean values, PowerShell handles this quite well on its own. You shouldn't need to cast explicitly to string in most cases since the framework manages that for you.
You can try simply doing this to convert `Aktiv` to a string:
```powershell
$foo.Aktiv = [string]$foo.Aktiv
```
But if it still doesn't work, it might be because of the object type. It's important to know what type `$foo` is. You might need to create a new object with the desired property type instead of changing it directly if it’s strongly typed.
I actually ran into the same error before. Make sure you're not trying to change a property type if it's already defined. It might be good to double-check your object types.
You might not need to convert the Boolean to a string explicitly if your logic is just checking for true or false. Just set:
```powershell
if ($foo.Aktiv -eq $true) {
$foo.Aktiv = "Inaktiv"
} else {
$foo.Aktiv = "Aktiv"
}
```
This way, you're directly setting the string based on the Boolean check without casting, and it should simplify things.
Definitely check that! I also found it works fine with both PowerShell 5.1 and 7.5. Make sure the environment matches.
