示例
以下示例实现一myWriter个名为 TextWriterTraceListener 的 以写入控制台屏幕。 该示例将两行写入控制台屏幕。 请注意，第二次写入与第一次写入在同一行中显示。 然后，该示例刷新并关闭流。
void main()
{
#if defined(TRACE)
// Create a text writer that writes to the console screen and add
// it to the trace listeners.
TextWriterTraceListener^ myWriter = gcnew TextWriterTraceListener;
myWriter->Writer = System::Console::Out;
Trace::Listeners->Add( myWriter );
// Write the output to the console screen.
myWriter->Write( "Write to the Console screen. " );
myWriter->WriteLine( "Again, write to console screen." );
// Flush and close the output.
myWriter->Flush();
myWriter->Close();
#endif
}
public class Sample
{
public static void Main(string[] args)
{
/* Create a text writer that writes to the console screen and add
* it to the trace listeners */
TextWriterTraceListener myWriter = new TextWriterTraceListener();
myWriter.Writer = System.Console.Out;
Trace.Listeners.Add(myWriter);
// Write the output to the console screen.
myWriter.Write("Write to the Console screen. ");
myWriter.WriteLine("Again, write to console screen.");
// Flush and close the output.
myWriter.Flush();
myWriter.Close();
}
}
