C# using Powershell.AddParameter with two conditions

I'd like to call a PowerShell script in c#. In Terminal the command would look like

get-mailbox -RecipientTypeDetails "EquipmentMailbox","RoomMailbox"

I can get it to run if I just use one Recipient type, for example "RoomMailbox", this works fine.

ps.AddCommand("Get-Mailbox");
ps.AddParameter("RecipientTypeDetails" , "RoomMailbox");

but i dont know how to add EquipmentMailbox to the parameter conditions, so to show both types.

ps.AddCommand("Get-Mailbox");
ps.AddParameter("RecipientTypeDetails" , "RoomMailbox,EquipmentMailboxes");

Thanks!

You need to create an array to bind both arguments to the RecipientTypeDetails parameter. A simple way to test how arguments are bound is to define a simple PowerShell script:

public static Collection<PSObject> Run()
{
    using PowerShell ps = PowerShell.Create()
        .AddScript(@"
            [cmdletbinding()]
            param($RecipientTypeDetails)

            $PSBoundParameters
        ")
        .AddParameter(
            "RecipientTypeDetails",
            new string[] { "RoomMailbox", "EquipmentMailbox" });

    return ps.Invoke();
}

Alternatively, if the cmdlet has many parameters, you might find easier by using AddParameters instead:

public static Collection<PSObject> Run()
{
    using PowerShell ps = PowerShell.Create()
        .AddScript(@"
            [cmdletbinding()]
            param($foo, $bar, $baz)

            $PSBoundParameters
        ")
        .AddParameters(new Dictionary<string, object>()
        {
            { "foo", new string[] { "RoomMailbox", "EquipmentMailbox" } },
            { "bar", "hello" },
            { "baz", "world" }
        });

    return ps.Invoke();
}
