Hi Gurus,

I have created a custom object using this method,

$object = New-Object Object |

Add-Member NoteProperty MyField 5 -PassThru |

Add-Member ScriptMethod xTimesMyField {

param($x)

$x * $this.MyField

} -PassThru

$object

$object.xTimesMyField(10)

Now I want to create another object that inherits the properties and methods of this object. How do I do that ?

Thanks for the comments. I have a question here,

How do I create an object that inherits properties/methods of a super-class ?

I suggest considering a data table in Powershell, as it does retain the order in which the properties are added, and it is truly a data table versus a hash table.

I've started using PS just two weeks ago, and I am impressed. I am so much more productive in terms of scripting, super. Really a big thank you for explaining the Real Time problem with the PowerShell parser.

Hey Rinimbi, regarding the performance of PSObjects, Karl Prosser, mow, and Brandon Shell have been batting this around for a while. Check out the following URL and in the first sentence he links to other posts that benchmark various methods of creating custom objects.

But depending on your circumstances, I've found the best way to create a huge number of objects with uniform structure is to use the Add-Type cmdlet in PowerShell 2.0 to create an on-the-fly .NET class in C# syntax.

Very nice! When creating tens of thousands of custom objects, though, is this method (using a hash) the best for performance? If speed is more important than code elegance, what's the best way to create large numbers of custom objects with many (10+) new properties? Thanks!
