Powershell and one to many relationships / objects

问题

I have created a function that reads a directory listing and then the files contents for CNC program names/numbers. Each file have multiple program numbers which i have separated by "," and are passed on as a obj (see code below). I want to export this to XML to upload to a database having each of the program names in a seperate entry. Whats the best/easiest method to achieve this?

$obj = New-Object -TypeName PSObject
$obj | Add-Member -MemberType NoteProperty -Name FullFileName -Value $CNCProgFileName 
$obj | Add-Member -MemberType NoteProperty -Name ProgramName -Value $ProgramName

Creating a custom object like you are doing is good. I suggest creating a property that is an array so you can associate the many things in the array to one object.

$myListOfStuff = @()
$myListOfStuff += "Stuff"
$myListOfStuff += "More stuff"

$obj = New-Object PsObject @{
    FullFileName = $CNCProgFileName
    ProgramName = $ProgramName
    ListOfStuff = $myListOfStuff
}

You can see your list of stuff with Select-Object with -ExpandProperty like so: $obj | select -expand ListOfStuff.

In PowreShell 2.0 you can use the ConvertTo-Xml cmdlet to produce XML from your objects.
