여러 파일에 쓰기 Enterprise Library Logger

Question

Enterprise Library Logger를 사용하여 여러 파일을 날짜별로 그룹화 할 수 있습니까? 예를 들어 Trace-08-22-2011.log, Trace-08-23-2011.log를 예로들 수 있습니다.

Answer 2

예 (Enterprise-Library와 함께 제공되는 TraceListeners에는 포함되지만 포함되지 않음). 필요한 것은 커스텀 TraceListener이거나 적어도 트레이스 리스너 팩토리 (GetCreationExpression)로서 간접적으로 사용되는 TraceListenerData입니다.

당신이 기술 한 가장 쉬운 방법은 RollingFlatFileTraceListenerData에서 상속 받고 GetCreationExpression을 오버라이드하는 것입니다. 그것은 당신이 원하는대로 설정할 수있는 this.FileName 보호 필드가 있습니다. 예를 들어, 당신은 사용자 정의 토큰 (타임 스탬프)

/// <summary> 
    /// Returns a lambda expression that represents the creation of the trace listener described by this 
    /// configuration object. 
    /// </summary> 
    /// <returns>A lambda expression to create a trace listener.</returns> 
    protected override Expression<Func<TraceListener>> GetCreationExpression() 
    { 
     // Resolve tokens in FileName 
     string fileName = ResolveTokens(this.FileName); 

     return 
      () => 
       new RollingFlatFileTraceListener(
        fileName, 
        this.Header, 
        this.Footer, 
        Container.ResolvedIfNotNull<ILogFormatter>(this.Formatter), 
        this.RollSizeKB, 
        this.TimeStampPattern, 
        this.RollFileExistsBehavior, 
        this.RollInterval, 
        this.MaxArchivedFiles); 
    } 

그리고 구성 해결할 수 :

<add name="All Activities Flat File Trace Listener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" 
listenerDataType="Sample.CustomFlatFileTraceListenerData, Sample" 
fileName="%TEMP%\{timestamp}.log" 
footer="" formatter="Detail Text Formatter" rollFileExistsBehavior="Overwrite" 
rollInterval="Day" timeStampPattern="yyyy-MM-dd" maxArchivedFiles="10" />
