包:

System.Management v8.0.0

Source:

ManagementEventArgs.cs

保存 EventArrived 事件的事件数据。

public ref class EventArrivedEventArgs : System::Management::ManagementEventArgs

public class EventArrivedEventArgs : System.Management.ManagementEventArgs

type EventArrivedEventArgs = class
    inherit ManagementEventArgs

Public Class EventArrivedEventArgs
Inherits ManagementEventArgs

注解

以下异步示例设置 WMI 计时器以每秒引发一个事件，并在不再需要时将其删除。 ManagementEventWatcher定义传递 WMI 事件时引发的多个.NET Framework事件。 委托被附加到这些事件，以处理传入的数据。
