Örnekler

Aşağıdaki kod örneği, TraceSource izlemeleri dinleyicilerine iletmek için sınıfının kullanımını gösterir.The following code example shows the use of the TraceSource class to forward traces to listeners. Örnek, anahtar ve filtre kullanımını da gösterir.The example also demonstrates switch and filter usage.

Açıklamalar

TraceSourceSınıfı, uygulamalar tarafından uygulamayla ilişkilendirilebilen izlemeler üretmek için kullanılır.The TraceSource class is used by applications to produce traces that can be associated with the application. TraceSource olayları kolayca izlemenize, verileri izlemenize ve bilgilendirici izlemeler yapmanıza imkan tanıyan izleme yöntemleri sağlar.TraceSource provides tracing methods that allow you to easily trace events, trace data, and issue informational traces. İzleme çıkışı TraceSource , yapılandırma dosyası ayarları tarafından denetlenebilir.Trace output from TraceSource can be controlled by configuration file settings. Yapılandırma dosyası, uygulama yürütülebiliri olan klasörde bulunur ve. config dosya adı uzantısı eklenmiş uygulamanın adına sahiptir.The configuration file is located in the folder with the application executable and has the name of the application with the .config file name extension added. Örneğin, TraceSourceSample.exe için yapılandırma dosyasının adı TraceSourceSample.exe.config. Yapılandırma dosyası, izleme bilgilerinin gönderileceği yeri ve hangi etkinlik seviyelerinin izleneceğini belirlemek için kullanılabilir.For example, the name of the configuration file for TraceSourceSample.exe is TraceSourceSample.exe.config. The configuration file can be used to determine where the trace information is to be sent and what levels of activity are to be traced. Aşağıdaki örnek bir örnek uygulama yapılandırma dosyasının içeriğini gösterir.The following example shows the contents of a sample application configuration file.

<configuration>  
  <system.diagnostics>  
    <sources>  
      <source name="TraceTest" switchName="SourceSwitch"   
        switchType="System.Diagnostics.SourceSwitch" >  
        <listeners>  
          <add name="console" />  
          <remove name ="Default" />  
        </listeners>  
      </source>  
    </sources>  
    <switches>  
      <!-- You can set the level at which tracing is to occur -->  
      <add name="SourceSwitch" value="Warning" />  
        <!-- You can turn tracing off -->  
        <!--add name="SourceSwitch" value="Off" -->  
    </switches>  
    <sharedListeners>  
      <add name="console"   
        type="System.Diagnostics.ConsoleTraceListener"   
        initializeData="false"/>  
    </sharedListeners>  
    <trace autoflush="true" indentsize="4">  
      <listeners>  
        <add name="console" />  
      </listeners>  
    </trace>  
  </system.diagnostics>  
</configuration>  

TraceSourceSınıfı, genellikle uygulamanın adı olan bir kaynağın adı ile tanımlanır.The TraceSource class is identified by the name of a source, typically the name of the application. Belirli bir bileşenden gelen izleme iletileri belirli bir izleme kaynağı tarafından başlatılabilir ve bu bileşenden gelen tüm iletilerin kolayca tanımlanmasını sağlar.The trace messages coming from a particular component can be initiated by a particular trace source, allowing all messages coming from that component to be easily identified.

TraceSource izleme yöntemlerini tanımlar ancak gerçek anlamda izleme verileri oluşturma ve depolama için belirli bir mekanizma sağlamaz.TraceSource defines tracing methods but does not actually provide any specific mechanism for generating and storing tracing data. İzleme verileri, izleme kaynakları tarafından yüklenebilen eklentiler olan izleme dinleyicileri tarafından üretilir.The tracing data is produced by trace listeners, which are plug-ins that can be loaded by trace sources.

TraceListenerÖzelliği içinde depolanan koleksiyona veya buradan örnek ekleyerek veya kaldırarak izleme çıktısının hedefini özelleştirebilirsiniz TraceSource.Listeners .You can customize the tracing output's target by adding or removing TraceListener instances to or from the collection stored in the TraceSource.Listeners property. Varsayılan olarak, izleme çıktısı, sınıfının bir örneği kullanılarak üretilir DefaultTraceListener .By default, trace output is produced using an instance of the DefaultTraceListener class. Önceki yapılandırma dosyası örneği, DefaultTraceListener ConsoleTraceListener izleme kaynağı için izleme çıktısı oluşturmak üzere öğesini kaldırmayı ve eklemeyi gösterir.The preceding configuration file example demonstrates removing the DefaultTraceListener and adding a ConsoleTraceListener to produce the trace output for the trace source. Daha fazla bilgi için bkz. < dinleyiciler > ve < sharedListeners > .For more information, see <listeners> and <sharedListeners>.

SourceSwitchSınıfı, izleme çıkışını dinamik olarak denetlemek için araçlar sağlar.The SourceSwitch class provides the means to dynamically control the tracing output. Önceki yapılandırma dosyası örneği, izleme kaynağından izlemeyi nasıl kapakullanabileceğinizi ve izlemenin gerçekleştiği düzeyi denetlemenizi gösterir.The preceding configuration file example shows how you can turn off tracing from a trace source and control the level at which tracing occurs. Uygulamanızı yeniden derlemeden kaynak anahtarın değerini değiştirebilirsiniz.You can modify the value of the source switch without recompiling your application. Anahtar ayarlamak için yapılandırma dosyasını kullanma hakkında daha fazla bilgi için, bkz Switch . ve nasıl yapılır: Izleme anahtarları oluşturma, başlatma ve yapılandırma.For information on using the configuration file to set a switch, see Switch and How to: Create, Initialize and Configure Trace Switches.

TraceEventTypeNumaralandırma, izleme iletisinin olay türünü tanımlamak için kullanılır.The TraceEventType enumeration is used to define the event type of the trace message. İzleme filtreleri, TraceEventType bir İzleme dinleyicisinin Trace iletisini üretmesi gerekip gerekmediğini öğrenmek için öğesini kullanır.Trace filters use the TraceEventType to determine if a trace listener should produce the trace message.

İzleme dinleyicileri, isteğe bağlı olarak bir izleme filtresi aracılığıyla ek bir filtreleme katmanına sahip olabilir.The trace listeners can optionally have an additional layer of filtering through a trace filter. Bir İzleme dinleyicisinin ilişkili bir filtresi varsa, dinleyici, ShouldTrace izleme bilgilerinin oluşturulup oluşturulmayacağını belirlemede bu filtre üzerinde yöntemini çağırır.If a trace listener has an associated filter, the listener calls the ShouldTrace method on that filter to determine whether or not to produce the trace information.

İzleme dinleyicileri, Trace Indent IndentSize AutoFlush izleme çıkışını biçimlendirmek için ve sınıf özelliklerinin değerlerini kullanır.The trace listeners use the values of the Trace class properties Indent, IndentSize, and AutoFlush to format trace output. Yapılandırma dosyası özniteliklerini,, ve özelliklerini ayarlamak için Indent kullanabilirsiniz IndentSize AutoFlush .You can use configuration file attributes to set the Indent, IndentSize, and AutoFlush properties. Aşağıdaki örnek, AutoFlush özelliğini false ve IndentSize özelliğini 3 olarak ayarlar.The following example sets the AutoFlush property to false and the IndentSize property to 3.

<configuration>  
  <system.diagnostics>  
    <trace autoflush="false" indentsize="3" />  
  </system.diagnostics>  
</configuration>
