    // WebManagementEvent class.

        // identified only by their event code.

下面是配置文件的摘录，使 ASP.NET 能够使用自定义事件。

注解

ASP.NET 运行状况监视允许生产和运营人员管理已部署的 Web 应用程序。 命名空间 System.Web.Management 包含负责打包应用程序运行状况状态数据的运行状况事件类型和负责处理此数据的提供程序类型。 它还包含支持类型，这些类型有助于管理运行状况事件。

WebManagementEvent 是所有 ASP.NET 运行状况监视事件类型的基类。 它使用该 WebProcessInformation 类获取其派生类可用的进程信息。

继承者说明

设置自定义事件信息的显示格式时，请重写 FormatCustomEventDetails(WebEventFormatter) 方法，而不是 ToString 方法。 这将避免覆盖或篡改敏感系统信息。

为自定义事件指定的事件代码必须大于 WebExtendedBase。
