Ejemplos

En el ejemplo siguiente se implementa un TextWriterTraceListener objeto denominado myTextListener, que usa un StreamWriter llamado myOutputWriter para escribir en un archivo denominado TestFile.txt. En el ejemplo se crea el archivo, la secuencia y el escritor de texto, se escribe una línea de texto en el archivo y, a continuación, se vacía y se cierra la secuencia.

#using <System.dll>
using namespace System;
using namespace System::IO;
using namespace System::Diagnostics;

void main()
{
   #if defined(TRACE)
   TextWriterTraceListener^ myTextListener = nullptr;
   
   // Create a file for output named TestFile.txt.
   String^ myFileName = "TestFile.txt";
   StreamWriter^ myOutputWriter = gcnew StreamWriter( myFileName,true );
   
   // Add a TextWriterTraceListener for the file.
   if ( myOutputWriter )
   {
      myTextListener = gcnew TextWriterTraceListener( myOutputWriter );
      Trace::Listeners->Add( myTextListener );
   }

   // Write trace output to all trace listeners.
   Trace::WriteLine( 
      String::Concat( DateTime::Now.ToString(), " - Trace output" ) );
   if ( myTextListener )
   {
      // Remove and close the file writer/trace listener.
      myTextListener->Flush();
      Trace::Listeners->Remove( myTextListener );
      myTextListener->Close();
   }
   #endif
}
