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();
    }
}

Public Class Sample
    
    Public Shared Sub Main()
        ' Create a text writer that writes to the console screen and add
        ' it to the trace listeners 
        Dim myWriter As 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()
    End Sub

End Class
