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

'Declaration

'Usage
Dim instance As TextWriterTraceListener

instance.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.

      Dim myOutputWriter As 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.
