C# obtaining Powershell responses

Using PowerShell I can use

$myMB = Get-Mailbox -Identity "test@test.com"

then I can get any property by using $myMB.PropertyName, i.e.

Write-Host $myMB.Name
Write-Host $myMB.Alias

In C#, using PowerShell, when I send a PowerShell command and then collect the results (just showing the section that captures results below), it just captures the Name of the Mailbox. I'm assuming its just returning a string to the results collection, not the MB Object.

Collection<PSObject> results = ps.Invoke();
foreach (PSObject result in results)
{
 Debug.Writeline("Result: " + result.ToString());
}

How do I capture the rest of the properties?

Thanks!

As you've found, PowerShell wraps everything in the PSObject wrapper type.

Properties (whether dynamically added through PowerShell's own type system layer, or simply part of a wrapped .NET instance) are exposed via the Properties dictionary:

foreach (PSObject result in results)
{
    Debug.Writeline("Mailbox belongs to mailbox database: " + result.Properties["Database"].ToString());
}
