Setting object properties
Joachim Meyer
I'm having trouble setting the properties of an object I am using within a
PowerShell script. The code uses an assembly part of Configuration Manager
2007 (the managed SMS provider) and is based on C# example code included in
the Configuration Manager SDK. I also attached this example code to the
bottom of this posting.
Here's an excerpt from the PowerShell code:
$SMSCILocalizedProperties =
$wqlconnection.CreateEmbeddedObjectInstance('SMS_CI_LocalizedProperties')
$SMSCILocalizedProperties['DisplayName'].StringValue = $UpdateListName
$SMSCILocalizedProperties['LocaleID'].StringValue = $localeid
$newUpdateList = $wqlconnection.CreateInstance('SMS_AuthorizationList')
$newUpdateList['Updates'].IntegerArrayValue = $swupdates
So far the code works even though I do not really understand the last line.
I would have expected that the usual object syntax ($newUpdateList.Updates =
$swupdates) would work in this case but that's apparently not the case.
With the next line I receive an error:
$newUpdateList.SetArrayItems('LocalizedInformation',
@($SMSCILocalizedProperties))
Cannot convert argument "1", with value: "System.Object[]", for
"SetArrayItems" to type
"System.Collections.Generic.List`1[Microsoft.ConfigurationManagement.ManagementProvider.IResultObject]":
"Cannot convert "System.Object[]" to
"System.Collections.Generic.List`1[Microsoft.ConfigurationManagement.ManagementProvider.IResultObject]"."
Any idea how to set this property in PowerShell?
Thanks,
Joachim

Thanks for the answer but that did not help either, the script still cannot
convert the object.
I think it's better to start with an array with the proper data type in the
beginning instead of performing the type cast later. However, I figured it's
not so easy doing this with PowerShell (at least for me).
The C# code is:
List<IResultObject> newDescriptionInfo = new List <IResultObject>();
Creating an instance of System.Collections.Generic.List using Strings works:
PS C:\> $a = New-Object "System.Collections.Generic.List``1[System.String]"
PS C:\> $a.gettype()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True List`1 System.Object
But how do you create an instance of the generic list including objects
defined somewhere else?
PS C:\> $a = New-Object
"System.Collections.Generic.List``1[Microsoft.ConfigurationManagement.ManagementProvider.IResul
t
Object]"
New-Object : Cannot find type
[System.Collections.Generic.List`1[Microsoft.ConfigurationManagement.ManagementProvider.I
ResultObject]]: make sure the assembly containing this type is loaded.
At line:1 char:16
+ $a = New-Object <<<<
"System.Collections.Generic.List``1[Microsoft.ConfigurationManagement.ManagementProvider.IResul
tObject]"
<IResultObject> is defined in
microsoft.configurationmanagement.managementprovider.dll and loaded.
PS C:\> [AppDomain]::CurrentDomain.GetAssemblies() | ? {$_.location -match
"managementprovider.dll"} | select
FullName,GlobalAssemblyCache,ImageRuntimeVersion,ManifestModule | fl
FullName :
Microsoft.ConfigurationManagement.ManagementProvider, Version=4.0.6000.0,
Culture=neutral, Pub
licKeyToken=31bf3856ad364e35
GlobalAssemblyCache : False
ImageRuntimeVersion : v2.0.50727
ManifestModule :
Microsoft.ConfigurationManagement.ManagementProvider.dll
Any ideas on this? Thanks!
