EventLogEntryType

字段

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 case 语句都使用 EventLogEntryType 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 );

// 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);

' Check whether source exist in event log.
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
      ' Write a 'FailureAudit' entry in specified log of event log.
      myEventLog.WriteEntry(myMessage, EventLogEntryType.FailureAudit, myID)
   Case 5

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

注解

事件日志条目的类型为条目提供了其他信息。 应用程序在将条目写入事件日志时设置条目类型。

每个事件都必须是单个类型;不能为条目组合事件类型。 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。
