TextWriterTraceListener does not work

Question

Config file:

  <system.diagnostics>
    <trace>
      <listeners>
        <add name="Console" type="System.Diagnostics.ConsoleTraceListener" initializeData="false"></add>
        <add name="Text" type="System.Diagnostics.TextWriterTraceListener" initializeData="D:\uat\logs\bifit.log" traceOutputOptions="DateTime"></add>
      </listeners>
    </trace>
  </system.diagnostics>

The code:

  static void Main(string[] args)
        {
            try
            {
                Trace.WriteLine("Running BiFit Test Server.");
             }
         }

I can see the text in cosole window. And the file is created, but it empty. I remember there is something like Autoflush property somewhere?

Answer 1

You recall correctly - it is defined on the trace element:

<trace autoflush="true">
  ...
</trace>

autoflush - Optional attribute. Specifies whether the trace listeners automatically flush the output buffer after every write operation.

Thanks, but then this attribute applies to all listeners. But the console listeners works unlike file one. – Crural

@Captain Comic - Can't change how it works, I'm afraid. And does it matter if the console output buffer also gets flushed? – Gaut

@Captain Comic - Glad to have helped :) – Gaut

Answer 2

I think it's:

<system.diagnostics>
    <trace autoflush="true">
      ...
    </trace>
</system.diagnostics>

Answer 3

You could call Trace.Flush() once you are done with your Trace.Write type operations.
