add a parameter to the Get-Mailbox command. For instance, if you need to run Get-Mailbox -Server

MB001

, you need to use the pipeline.command.add method to add in Get-Mailbox as the command

that needs to run and then use the

command.Parameters.Add method to add Server and MB001 to

modify that command. The

CommandParameter class requires only a name in the case of a switch param-

eter and a name and a value for parameters that have additional values:

Runspace EMSRunSpace = RunspaceFactory.CreateRunspace();

EMSRunSpace.Open();

Pipeline pipeLine = EMSRunSpace.CreatePipeline();

Command MBXCommand = new Command(“Get-Mailbox”);

pipeLine.Commands.Add(MBXCommand);

CommandParameter verbParam = new CommandParameter(“Server”,

“MB001”);

EMSCmd.Parameters.Add(verbParam);

Command FTCommand = new Command(“Format-Table”);

pipeLine.Commands.Add(FTCommand);

Collection < PSObject > cmdResult = pipeLine.Invoke();

When adding commands to a pipeline this way, take care to ensure that the command is being passed

correctly typed data. Most of the cmdlets accept standard Int64, string, or byte quantified size for their

parameter values. However, a number of Exchange cmdlets have the

filterscript parameter and

this parameter requires a value typed as a

ScriptBlock and will not accept a string value. Creating a

ScriptBlock value isn ’ t as straightforward ...
