对象a ManagementObject 例子索引器可以将返回值作为 Base

Private Shared Sub EventArrived(ByVal sender As Object, ByVal e As EventArrivedEventArgs)
    Dim targetInstance As ManagementBaseObject = e.NewEvent("TargetInstance")

    If TypeOf targetInstance Is ManagementObject Then
        Dim mo as ManagementObject = DirectCast(targetInstance, ManagementObject)
        Dim output(1) as String

        mo.InvokeMethod("GetOwner", output)

        Console.WriteLine("Process {0} started by {2}\{1}", targetInstance("Name"), output(0), output(1))
    End If
End Sub
