我正在开发一个小程序，以使我的工作生活更轻松。它会查找用户名、主机名、MAC 地址和 IP 地址。

当用户将鼠标悬停在系统托盘图标上时，将出现一个包含所有信息的工具提示。截至目前，它工作得很好，除非出现新的网络连接，否则它不会获得 IP。

我必须关闭程序并重新打开它才能获得新的 IP 地址。我该怎么做才能在不重新启动我的应用程序的情况下获取新检测到的网络连接的 IP 地址。

我不认为我想要定时刷新，它可能会占用太多资源。我包括了我的申请中的肉和土豆。

您可以在数据更改时广播信号，并将您的函数注册到侦听该广播的侦听器。registerReceiver 可用于以后和广播信号，它们应该是 C# 中的某些函数，例如 android 中的 Intent。

您可以添加事件 NetworkChange.NetworkAddressChanged 并采取措施更新数据，例如：

        static void Main(string[] args) 
        { 
              try 
              { 
                    NetworkChange.NetworkAddressChanged += new NetworkAddressChangedEventHandler(NetworkChange_NetworkAddressChanged); 
                    Console.ReadLine(); 
              } 
              catch (Exception e) 
              { 
                    Console.WriteLine(e); 
              } 
        } 

        static void NetworkChange_NetworkAddressChanged(object sender, EventArgs e) 
        { 
              Console.WriteLine(" do Something"); 
        }
