This code breaks on PowerShell 2. Are arbitrary delegates supported by PowerShell 2.0 out of the box?

I'd like to see a solution to Colin's problem myself. I've been trying to solve it for a while now, but the IL is over my head.

I've detected the same problem as already posted by Colin Bowern.

Is this not important enough to give it your attention?

Hey, Jeff and Bruce, give it the necessary attention, please. Don't forget we are your customers!

I hope this helps!

Thank you.

Cool script, but crashs PowerShell with the following:

PS E:\> $d = &get-delegate System.Threading.WaitCallback `

>> {

>> echo $args[0]

>> }

PS E:\> [System.Threading.ThreadPool]::QueueUserWorkItem ($d, "test")

Can you use this to create a thread using PowerShell?

I'm trying to create a Predicate using this method but the result isn't correct:

$domains = New-Object "System.Collections.Generic.List``1[System.String]";

$domains.Add("foo.com");

$uri = New-Object System.Uri("http://bar.com");

$delegate = get-delegate "System.Predicate``1[System.String]" { Write-Host $uri.Host " : " $args " = " ([String]::Compare($uri.Host, $args[0], $true) -eq 0); return ([String]::Compare($uri.Host, $args[0], $true) -eq 0); };

$domains.Exists($delegate);

The call to Exists returns true even though bar.com isn't in the collection.

Thoughts on how where I'm going wrong?

You updated the script on the page, but not in the attachment. If you use this utility, be sure to use version on the Blog page.

Is it possible to pass a powershell function as a delegate parameter to a .NET method?
