重复日志条目Nlog

Question

我使用Nlog进行日志记录,我发现每次调用nLog时我的日志文件中都有5个条目.我该如何解决？例如.

2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup
2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup
2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup
2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup
2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup
2012-12-23 18:18:19.2465 NinjaTrader.Strategy.LODHOD.OnStartUp Debug   startup

我的nLog配置如下

/****CLASS LEVEL VARIABLES***/
// Step 1. Create configuration object 
private static LoggingConfiguration config = new LoggingConfiguration();
private static FileTarget fileTarget = new FileTarget();
private static Logger logger = LogManager.GetCurrentClassLogger();
/*** END OF CLASS LEVEL VARIABLES ***/

/*************************NLOG CONFIG*****/

fileTarget.FileName = 
  "C:\\temp\\" + Instrument.FullName + "nLog." + DateTime.Now.Ticks + ".log";
fileTarget.Layout = 
  "${longdate} ${callsite} ${level} ${event-context:item=StrategyId}  ${message}";

config.AddTarget("file", fileTarget);

// Step 4. Define rules
LoggingRule rule2 = new LoggingRule("*", NLog.LogLevel.Trace, fileTarget);
config.LoggingRules.Add(rule2);

// Step 5. Activate the configuration
LogManager.Configuration = config;


logger.Debug("startup");


/*************************NLOG CONFIG*****/

你可以看到starup打印了6次,并且在Ninjatrader onStartup程序开始时程序中只调用一次.

我也有范围的全球诊断,但我认为这不会导致这种情况发生

public class ScopedGlobalContext : IDisposable
{
  private string n;
  private string v;

  public ScopedGlobalContext(string name, string value)
  {
    n = name;
    v = value;
    NLog.GlobalDiagnosticsContext.Set(n, v);
  }

  public void Dispose()
  {
    NLog.GlobalDiagnosticsContext.Remove(n);
  }
}

如果您有多个针对实例文件的规则,那么您将获得多次写入.
