PowerShell ParameterBindingException

I am currently building an application to automate some Exchange 2010 operations from a ASP.NET MVC website.

Right now, I've run into a ParameterBindingException when I try to invoke the New-AddressList command.

I am trying to create the following call (which works):

new-AddressList -Name "7 AL" -RecipientContainer "myDomain.local/Customers/7" -IncludedRecipients 'AllRecipients' -Container '\' -DisplayName "7 AL"

I am doing it by the following:

var NewAddressList = new Command("New-AddressList");
NewAddressList.Parameters.Add("Name", "7 AL");
NewAddressList.Parameters.Add("RecipientContainer", "myDomain.local/Customers/7");
NewAddressList.Parameters.Add("IncludedRecipients", "AllRecipients");
NewAddressList.Parameters.Add("Container", @"\");
NewAddressList.Parameters.Add("DisplayName", "7 AL");
CommandsList.Add(NewAddressList);

This commandlist is provided to a pipeline which I invoke, giving me the following error:

New-AddressList: The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.

CategoryInfo: InvalidArgument: (7:PSObject) [New-AddressList], ParameterBindingException
FullyQualifiedErrorId: InputObjectNotBound,Microsoft.Exchange.Management.SystemConfigurationTasks.NewAddressList

Any clues to what might cause this?

Output with Trace-Command gives:

回答1:

I found that each command must be invoked separately, since they are not related. The question arose from my misunderstanding of the concept of Powershell pipelines.

回答2:

Why are you declaring command as var? I mean:

Command NewAddressList = new Command("New-AddressList");

Then, try adding commands as CommandParameter objects (as suggested here):

CommandParameter NameParam = new CommandParameter("Name","7 AL");
NewAddressList.Parameters.Add(NameParam);

Finally, why are you not using the Powershell class directly?

EDIT: Further guess after tracing

The overloaded version of Parameters.Add you are using takes as arguments a key (string) and a value (object). Probably c# does not do the same good job powershell does :/. Try passing values as objects of the required type. For example, the included-recipient parameter wants a Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType.

Try casts.

Example:

Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType allrecips = (Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType) "AllRecipients";
NewAddressList.Parameters.Add("IncludedRecipients", allrecips);

or (I know it may be silly):

NewAddressList.Parameters.Add("IncludedRecipients", "[Microsoft.Exchange.Data.Directory.Recipient.WellKnownRecipientType] AllRecipients");
