TextWriterTraceListener.Flush Method

Flushes the output buffer for the Writer.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public override void Flush()

The following example implements a TextWriterTraceListener named myTextListener, which uses a StreamWriter called myOutputWriter to write to a file named TestFile.txt. The example creates the file, stream, and text writer, writes one line of text to the file, and then flushes and closes the stream.

#define TRACE

using System;
using System.IO;
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();
    }
}
