How would I return an object or multiple values from PowerShell to executing C# code

Question

Some C# code executes a powershell script with arguments. I want to get a returncode and a string back from Powershell to know, if everything was ok inside the Powershell script

Answer 1

CB.'s answer worked great for me with a minor change. I did not see this posted anywhere (in regards to C# and PowerShell) so I wanted to post it.

In my PowerShell script I created created a Hashtable, stored 2 values in it (a Boolean and an Int) and then converted that into a PSObject:

$Obj = @{}

if($RoundedResults -ilt $Threshold)
{
    $Obj.bool = $true
    $Obj.value = $RoundedResults
}
else
{
    $Obj.bool = $false
    $Obj.value = $RoundedResults
}

$ResultObj = (New-Object PSObject -Property $Obj)

return $ResultObj

And then in my C# code I did the same thing that CB. did but I had to use Convert.ToString in order to successfully get the values back:

ReturnInfo ri = new ReturnInfo();
foreach (PSObject p in psObjects)
   {
     ri.ReturnCode = Convert.ToBoolean(p.Properties["ReturnCode"].Value;)
     ri.ReturnText = Convert.ToString(p.Properties["ReturnString"].Value;)
   }

I found the answer to this via the following StackOverflow post: https://stackoverflow.com/a/5577500

Where Kieren Johnstone says:

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)
