Question

我已经实例化了2个FileSystemWatcher，我现在想要的是同步两个filesystemwatcher。截至目前，此处是日志的示例输出:(注意格式的更改是指其他FSM，反之亦然）

Dec 15 15:28:19,8167876|: INFO   |Web server call start_device_discovery() for: 10.191.20.0
Dec 15 15:28:19,8167876|: START  |      Device discovery started for: 10.191.20.0

2011-12-15 15:28:19,785|  INFO | SNMPDiscovery - Starting discovery for NET_10.191.20.0_24.

请仔细看看他们的时间。 15：28：19,8167876ms的声明在15：28：19,785ms之前首次输出

2011-12-15 15:28:19,785|  INFO | NetworkList - setStartDiscovery - Starting point

我想做的是尝试同步这两位观察者。有任何想法吗？谢谢。

您可以尝试同步日志访问。为此，您需要一个简单的对象进行同步，所有FileSystemWatcher事件处理程序都可以访问该对象。为简化起见，您可以使用logger对象（但请阅读remarks section here）。 FileSystemWatcher获得通知后立即获取锁：

private static void OnChanged(object source, FileSystemEventArgs e)
{
    lock(MyLogger)
    {
        MyLogger.Log("something changed");
    }
}

确保在使用记录器的任何地方锁定。
