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::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();
