【问题描述】:
NLog 没有使用异步滚动文件记录器配置记录每条日志消息。
以下是我的 NLog.config xml。
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
autoReload="true"
throwExceptions="false"
internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log" >
<targets async="true">
<target name="logfile" xsi:type="File" fileName="logs/log.txt"
maxArchiveFiles="10"
archiveAboveSize="1048576"
archiveNumbering="Sequence"
concurrentWrites="true"
archiveFileName="logs/log.{####}.txt"/>
</target>
</targets>
<rules>
<logger name="*" minlevel="Debug" writeTo="logfile" />
</rules>
</nlog>
以下是我的代码。
private static Logger log = LogManager.GetCurrentClassLogger();
Stopwatch sw = new Stopwatch();
public Form1()
{
InitializeComponent();
LogManager.ReconfigExistingLoggers();
}
private void button1_Click(object sender, EventArgs e)
{
string toLog;
sw.Start();
for (int i = 0; i < 100000; i++)
{
toLog = "Message:" + i.ToString();
log.Debug(toLog);
}
sw.Stop();
string s = "STOP :" + sw.Elapsed.ToString();
log.Debug(s);
}
结果我只得到一个文件,并且缺少一些日志条目。以下是生成的 log.txt 文件。

但是,当我删除 async 属性时,代码运行正常。
