passing object reference from sequence to C#

hi all,

I'm trying to pass a simple array that was created in locals at the sequence to a UI application.

I created an expression in NI:

RunState.Thread.PostUIMessageEx(10201,454,"this is my test",Locals.arr,True)

and in the application i implemented:

private void axApplicationMgr_UIMessageEvent(object sender, NationalInstruments.TestStand.Interop.UI.Ax._ApplicationMgrEvents_UIMessageEventEvent e)
{
            if (e.uiMsg.Event == (NationalInstruments.TestStand.Interop.API.UIMessageCodes)10201)
            {
               
            }
}

when the expression executed the UIMessageEvent happend and I get the numericData (454) and the stringData ( this is my test) but I don't know How to get the object reference of the array.

How can I cast the object ( e ) to get the array.

Tnx
