The following code:
static void Main(string[] args)
{
TraceSource ts = new TraceSource("MyApplication");
ts.Switch = new SourceSwitch("MySwitch");
ts.Switch.Level = SourceLevels.All;
ts.Listeners.Add(new TextWriterTraceListener(Console.Out));
ts.TraceInformation("Hello World");
Console.ReadKey();
}
generates the following output:
MyApplication Information: 0 : Hello World
The part "MyApplication Information: 0 :" at the beginning of the trace output is coming from the TraceSource class itself.
However, I need to have a timestamp at the beginning of the line and I would like to change "Information" to "Info" also.
Is there any way to get more freedom in trace output such that I can configure it to be like:
13:03:00 - MyApplication Info: Hello World
I tried for a couple of hours, but with no success. Whatever I do, at the beginning of the output line, there is always this constant predefined "MyApplication Information: 0 : Hello World" output.
MSDN documentation did also not reveal any helpful information.
Coming in late also but in case someone else lands here...
I like keeping it simple. I use one static Trace method within my App.cs which ties to a single TraceSource that I create at start up. This allows me access it throughout my app and keep the app.config simple:
public static void Trace(TraceEventType eventType, string message)
{
if (_TraceSource.Switch.ShouldTrace(eventType))
{
string tracemessage = string.Format("{0}\t[{1}]\t{2}", DateTime.Now.ToString("MM/dd/yy HH:mm:ss"), eventType, message);
foreach (TraceListener listener in _TraceSource.Listeners)
{
listener.WriteLine(tracemessage);
listener.Flush();
}
}
}
My app.config entries:
<system.diagnostics>
<sources>
<source name="mytracesource" switchValue="All">
<listeners>
<add name="mytracelistener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="trace.log">
</add>
</listeners>
</source>
</sources>
</system.diagnostics>
