What is the best way to take a file path as a parameter?

    Question

  • I am currently taking the file path as a String parameter using the following code to validate the file extension is correct.

    [Parameter(Mandatory=$true, Position=0, ParameterSetName="Path")]
    [ValidateScript({($_.EndsWith(".xaml") -and (Test-Path $_))})]
    [String]$path

    Is there a better way to ensure that the parameter provided is a valid path to an existing file of a certain extension?

    Thanks in advance!

  • What is wrong with the method you are using?

  • Nothing is wrong with it from my view, however I have no means of consulting with other developers in my current role and I'm cobbling together code found out and about on the internet. This particular solution felt wrong as I've never implemented code as part of a parameter declaration before, and I felt there might be a more effective solution.

    I suppose a better way to phrase the question would be, "Is there anything wrong with doing [thing]?"

  • No.  That is what ValidateScript is for.
