示例

下面的代码示例有两个部分。第一个是配置文件的摘录，它使 ASP.NET 运行状况监视能够使用派生自WebBaseErrorEvent类的事件。第二个说明如何派生自 WebBaseErrorEvent 类以创建自定义事件。

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。

该 WebBaseErrorEvent 类是表示错误条件的运行状况监视事件的基类。 ASP.NET 使用WebBaseErrorEvent及其派生类型来指示 Web 应用程序的生存期内的错误条件。

备注

在大多数情况下，你将能够使用实现的 ASP.NET 运行状况监视类型，并通过在healthMonitoring配置部分中指定值来控制运行状况监视系统。还可以从运行状况监视类型派生，以创建自己的自定义事件和提供程序。有关从 WebBaseErrorEvent 类派生的示例，请参阅本主题中提供的示例。

构造函数

WebBaseErrorEvent(String, Object, Int32, Exception)	初始化 WebBaseErrorEvent 类的新实例。
WebBaseErrorEvent(String, Object, Int32, Int32, Exception)	初始化 WebBaseErrorEvent 类的新实例。

属性

ErrorException	获取与此错误关联的 Exception。
EventCode	获取与该事件关联的代码值。 (继承自 WebBaseEvent)
EventDetailCode	获取事件详细信息代码。 (继承自 WebBaseEvent)
EventID	获取与事件关联的标识符。 (继承自 WebBaseEvent)
EventOccurrence	获取表示事件发生次数的计数器。 (继承自 WebBaseEvent)
EventSequence	获取应用程序已引发事件的次数。 (继承自 WebBaseEvent)
EventSource	获取引发事件的对象。 (继承自 WebBaseEvent)
EventTime	获取引发事件的时间。 (继承自 WebBaseEvent)
EventTimeUtc	获取引发事件的时间。 (继承自 WebBaseEvent)
Message	获取描述事件的消息。 (继承自 WebBaseEvent)
ProcessInformation	获取有关 ASP.NET 应用程序承载进程的信息。 (继承自 WebManagementEvent)

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
FormatCustomEventDetails(WebEventFormatter)	提供事件信息的标准格式设置。 (继承自 WebBaseEvent)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
IncrementPerfCounters()	递增与性能相关的事件-错误计数器。
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
Raise()	通过将事件已发生这一情况通知任何已配置的提供程序来引发事件。 (继承自 WebBaseEvent)
ToString()	为显示而对事件信息进行格式化。 (继承自 WebBaseEvent)
ToString(Boolean, Boolean)	为显示而对事件信息进行格式化。 (继承自 WebBaseEvent)
