function Get-ParameterValues { <# .Synopsis Get the actual values of parameters which have manually set default values or values passed in the call .Description Unlike $PSBoundParameters, the hashtable returned from Get-ParameterValues includes non-empty default parameter values. NOTE: Default values that are the same as the implied values are ignored (e.g.: empty strings, zero numbers, nulls). .Link https://gist.github.com/Jaykul/72f30dce2cca55e8cd73e97670db0b09/ .Link https://gist.github.com/elovelan/d697882b99d24f1b637c7e7a97f721f2/ .Example function Test-Parameters { [CmdletBinding()] param( $Name = $Env:UserName, $Age ) $Parameters = Get-ParameterValues # This WILL ALWAYS have a value...
