我真的很努力地獲得一個使用NLog的基本自定義目標。無法讓NLog自定義目標正常工作
的Program.cs
using NLog;
using NLog.Targets;
namespace NLogTestConsole
{
class Program
{
private static Logger logger = null;
static Program()
{
logger = LogManager.GetCurrentClassLogger();
Target.Register<NLogTestConsole.Gerald>("Gerald");
}
static void Main(string[] args)
{
logger.Trace("Sample trace message");
logger.Debug("Sample debug message");
logger.Info("Sample informational message");
logger.Warn("Sample warning message");
logger.Error("Sample error message");
logger.Fatal("Sample fatal error message");
}
}
}
NLogCustomTarget.cs
using NLog;
using NLog.Targets;
namespace NLogTestConsole
{
[Target("Gerald")]
public sealed class Gerald : TargetWithLayout
{
public Gerald()
{
// this.Host = "localhost";
}
//[RequiredParameter]
//public string Host { get; set; }
protected override void Write(LogEventInfo logEvent)
{
// Breakpoint here never gets hit
string logMessage = this.Layout.Render(logEvent);
System.Console.WriteLine("MYCUSTOMMSG: " + logMessage);
}
private void SendTheMessageToRemoteHost(string host, string message)
{
// TODO - write me
}
}
}
NLog.config
<?xml version="1.0" encoding="utf-8" ?>
<nlog autoReload="true"
throwExceptions="false"
internalLogLevel="Off"
internalLogFile="c:\temp\nlog-internal.log">

<target name="console" type="Console" />
<target name="debugger" type="Debugger"/>
<target name="Gerald" type="Gerald"/>
</targets>
<rules>
<!-- Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace) to "f"

<logger name="*" minlevel="Trace" writeTo="logfile" />
<logger name="*" minlevel="Info" writeTo="console" />

<logger name="*" minlevel="Trace" writeTo="Gerald" />
</rules>
</nlog>
如果我註釋掉 「傑拉德」 的目標我得到記錄到文件,控制檯,並調試輸出。隨着那條線,沒有任何工作 我有什麼問題?
謝謝,
亞當。
這給了我我需要的線索。謝謝,朱利安。在對Target.Register的調用之後,顯然需要創建記錄器*。 –
