MSDN - ManagementEventWatcher.WaitForNextEvent Method () 大家好, 我正在使用WMI事件__InstanceOperationEvent监视设备。链接中的示例代码适用于Windows 10英文或简体中文,但不适用于法语。 根本原因是WaitForNextEvent返回null,以使我的程序崩溃。 有解决这个问题的主意吗?谢谢! 以下是我实施的方法:

static int Main(string[] args)
{       
    ManagementScope scope = new ManagementScope("root\\CIMV2", options);
    scope.Options.EnablePrivileges = true;

    WqlEventQuery query =                
        new WqlEventQuery("__InstanceOperationEvent",
        new TimeSpan(0, 0, 1),                
        "TargetInstance isa \"Win32_NetworkAdapter\"");            
    ManagementEventWatcher watcher =
        new ManagementEventWatcher();
    watcher.Query = query;            
    watcher.Options.Timeout = new TimeSpan(0, 0, 5);           
    ManagementBaseObject e = watcher.WaitForNextEvent(); // return null to e under French OS


    //Cancel the subscription
    watcher.Stop();
    return 0;
}
