Tracing/Logging to a text file question

[Natalia DeBow]

Hi,

I am using .NET provided Trace class for tracing purposes in my code:
[code snippet]
serverLogFile = new FileStream("C:\\Temp\\log.txt", FileMode.Append,
FileAccess.Write, FileShare.ReadWrite);

TextWriterTraceListener serverTraceListener = new
TextWriterTraceListener(serverLogFile);

if (!System.Diagnostics.Trace.Listeners.Contains(serverTraceListener))

{

System.Diagnostics.Trace.Listeners.Add(serverTraceListener);

}

........

and in another method I have the follwoing code:

........

try

{

System.Diagnostics.Trace.WriteLine(Format(moduleName, className,
functionName, errorMessage));

System.Diagnostics.Trace.Flush();

}

catch(IOException ioe)

{

EventLogEntryType type = EventLogEntryType.Warning;

EventLog("Exception logging information into a log file" + ioe.Message,
type);

}

catch (Exception e)

{

EventLogEntryType type = EventLogEntryType.Warning;

EventLog("Exception logging information into a log file" +
e.StackTrace.ToString(), type);

}

I have a question with writing to a TextWriter Trace Listener. If I have
multiple simultaneous writes to the same trace listener, would it preserve
data integrity? I'm having trouble simulating this scenario and I am
wondering if I need to lock the FileStream before I do Trace.WriteLine().
How is Trace.Write()/WriteLine() is actually implemented? Does it block
while the main thread is writing to the file or does it do it
asynchronously?



Thanks so much in advance,

Natalia

Tracing is usually done on the internal workings right ? so, it need not
be done through asynchronous threads.
