线程和调用Windows服务中的方法

Question

我正在将此项目作为Windows服务实现。我试图找出本地的开放网络接口并记录它们。当在网络接口的变化newAdapterNotifier方法触发

public void newAdapterNotifier(object sender, EventArrivedEventArgs e) //Change in network 
    { 
     checkNetworkAdapters(); 
    } 

这种方法是通过WMI触发我的意思是;

ManagementEventWatcher watcher = null; 
query = new WqlEventQuery(); 
query.EventClassName = "__InstanceOperationEvent"; 
query.WithinInterval = new TimeSpan(0, 0, 1); 
query.Condition = @"TargetInstance ISA 'Win32_NetworkAdapter' AND TargetInstance.NetConnectionStatus IS NOT NULL"; 
watcher = new ManagementEventWatcher(scope, query); 
watcher.EventArrived += new EventArrivedEventHandler(newAdapterNotifier); 

在newAdapterNotifier我打电话给checkNetworkAdapters它没有给出任何错误，但没有工作太多。在WindowsForms中，我只是做了相同的代码，只有一个区别，那就是工作!!!

public delegate void ControlNetworkAdapter(); 
public void newAdapterNotifier(object sender, EventArrivedEventArgs e) //Change in network 
{ 
    this.Invoke(new ControlNetworkAdapter(checkNetworkAdapters)); 
} 

由于在Windows服务应用程序中没有Invoke方法，它不起作用。我该如何解决它？类的

我解决了这个问题。这是关于计时器。我们不能在Windows服务中使用System.Windows.Forms.Timer ..我们需要使用其他的..但是它是哪一个？
