EventLogEntryType 枚举

指定事件日志项的事件类型。

**命名空间:**System.Diagnostics
**程序集:**System（在 system.dll 中）

语法

声明
Public Enumeration EventLogEntryType
用法
Dim instance As EventLogEntryType

public enum EventLogEntryType

public enum class EventLogEntryType

public enum EventLogEntryType

public enum EventLogEntryType

成员

	成员名称	说明
	Error	错误事件。它指示用户应该知道的严重问题（通常是功能或数据的丢失）。
	FailureAudit	失败审核事件。它指示当审核访问尝试失败（例如打开文件的尝试失败）时发生的安全事件。
	Information	信息事件。它指示重要、成功的操作。
	SuccessAudit	成功审核事件。它指示当审核访问尝试成功（例如成功登录）时发生的安全事件。
	Warning	警告事件。它指示并不立即具有重要性的问题，但此问题可能表示将来会导致问题的条件。

备注

事件日志项的类型可为该项提供附加信息。应用程序在事件日志中写入一个日志项时会设置该项的类型。

每个事件必须具有单一的类型；不能在一个日志项中组合多个事件类型。事件查看器使用该类型来确定在日志的列表视图中显示哪一个图标。
