Exemples

L’exemple suivant implémente un TextWriterTraceListener nommé myTextListener, qui utilise un StreamWriter appelé myOutputWriter pour écrire dans un fichier nommé TestFile.txt. L’exemple crée le fichier, le flux et l’enregistreur de texte, écrit une ligne de texte dans le fichier, puis vide et ferme le flux.

#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
}

#define TRACE

using System;

using System.Diagnostics;

public class TextWriterTraceListenerSample
{
    public static void Main()
    {
        TextWriterTraceListener myTextListener = null;

        // Create a file for output named TestFile.txt.
        string myFileName = "TestFile.txt";
        StreamWriter myOutputWriter = new StreamWriter(myFileName, true);

        // Add a TextWriterTraceListener for the file.
        myTextListener = new TextWriterTraceListener(myOutputWriter);
        Trace.Listeners.Add(myTextListener);

        // Write trace output to all trace listeners.
        Trace.WriteLine(DateTime.Now.ToString() + " - Trace output");

        // Remove and close the file writer/trace listener.
        myTextListener.Flush();
        Trace.Listeners.Remove(myTextListener);
        myTextListener.Close();
    }
