用反射对象运行线程的vb.net

遇到通过反射创建对象的问题,然后在多个线程上运行它们。

我只是不明白我在这里需要什么:

            For Each WorkerNode As XmlNode In oRunSettings.GetWorkerValues
                Dim sWorkerName = WorkerNode.Attributes(SETTING_NAME_ID).Value
                Dim oWorkerType As Type = Type.GetType(String.Format("Worker.{0}", sWorkerName))
                Dim oWorker As Object = Activator.CreateInstance(oWorkerType)
                Dim tWorker As Thread = New Thread(AddressOf oWorker.Process)
                tWorker.Start()
            Next

它在“AddressOf”处导致错误,因为对象没有调用它的方法。我需要用接口做些什么吗?
