There are numerous ways how you can create new objects that you may use to return results from your functions. One way is using JSON, a very simple description language. It is fully supported in PowerShell 3.0. Have a look:
PS> $content = '{"Name":"weltner","FirstName":"tobias","id":123}' PS> ConvertFrom-Json $content Name FirstName id ---- ------- -- weltner tobias 123
