public enum class EventLogEntryTypepublic enum EventLogEntryTypetype EventLogEntryType = Public Enum EventLogEntryType- 继承
字段
| 名称 | 值 | 说明 |
|---|---|---|
| Error | 1 | 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 | 16 | 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 | 4 | 信息事件。 它指示重要、成功的操作。 |
| SuccessAudit | 8 | 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 | 2 | 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。 |
示例
下面的代码示例演示如何使用 EventLogEntryType 类将有关触发事件的信息添加到日志文件。 在此示例中， switch 语句用于确定事件类型。 每个语句使用 caseEventLogEntryType 指定事件类型，获取消息和 ID，然后将信息写入日志。
// Check whether source exist in event log.
if ( !EventLog::SourceExists( mySource ) )
{
// Create a new source in a specified log on a system.
EventLog::CreateEventSource( mySource, myLog );
}
// Create an event log instance.* myEventLog = new EventLog(myLog);
// Initialize source property of obtained instance.
myEventLog->Source = mySource;
switch ( myIntLog )
{
case 1:
// Write an 'Error' entry in specified log of event log.
myEventLog->WriteEntry( myMessage, EventLogEntryType::Error, myID );
break;
case 2:
// Write a 'Warning' entry in specified log of event log.
myEventLog->WriteEntry( myMessage, EventLogEntryType::Warning, myID );
break;
case 3:
// Write an 'Information' entry in specified log of event log.
myEventLog->WriteEntry( myMessage, EventLogEntryType::Information, myID );
break;
case 4:
// Write a 'FailureAudit' entry in specified log of event log.
myEventLog->WriteEntry( myMessage, EventLogEntryType::FailureAudit, myID );
break;
case 5:
// Write a 'SuccessAudit' entry in specified log of event log.
myEventLog->WriteEntry( myMessage, EventLogEntryType::SuccessAudit, myID );
break;
default:
Console::WriteLine( "Error: Failed to create an event in event log." );
break;
}
Console::WriteLine( "A new event in log '{0}' with ID '{1}' is successfully written into event log.", myEventLog->Log, myID );

myEventLog.WriteEntry(myMessage, EventLogEntryType.Information, myID);
break;
case 4:
// Write a 'FailureAudit' entry in specified log of event log.
myEventLog.WriteEntry(myMessage, EventLogEntryType.FailureAudit, myID);
break;
case 5:

break;
default:
Console.WriteLine("Error: Failed to create an event in event log.");
break;
}
Console.WriteLine("A new event in log '{0}' with ID '{1}' "
+ "is successfully written into event log.",
myEventLog.Log, myID);

If False = EventLog.SourceExists(mySource) Then
' Create a new source in a specified log on a system.
EventLog.CreateEventSource(mySource, myLog)
End If
' Create an event log instance.
myEventLog = New EventLog(myLog)
' Initialize source property of obtained instance.
myEventLog.Source = mySource
Select Case myIntLog
Case 1
' Write an 'Error' entry in specified log of event log.
myEventLog.WriteEntry(myMessage, EventLogEntryType.Error, myID)
Case 2
' Write a 'Warning' entry in specified log of event log.
myEventLog.WriteEntry(myMessage, EventLogEntryType.Warning, myID)
Case 3
' Write an 'Information' entry in specified log of event log.
myEventLog.WriteEntry(myMessage, EventLogEntryType.Information, myID)
Case 4

myEventLog.WriteEntry(myMessage, EventLogEntryType.FailureAudit, myID)
Case 5

myEventLog.WriteEntry(myMessage, EventLogEntryType.SuccessAudit, myID)
Case Else

End Select

注解
事件日志条目的类型提供条目的其他信息。 应用程序在将条目写入事件日志时设置条目类型。
每个事件必须属于单个类型;不能组合条目的事件类型。 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。
