Title Body

I have a TraceSource object that I use to log the initialization of a VB.Net application. It has several TraceListeners attached: ConsoleTraceListener TextWriterTraceListener EventLogTraceListener For the first two I want the entry output to be "raw" - that is, without the standard header: SourceName TraceEventType: Id : I have implemented a wrapper that does this when the TraceEventType is set to Verbose: If _buffer.EventType = TraceEventType.Verbose Then For Each listener As TraceListener In _traceSource.Listeners listener.Write(_buffer.Text) Next Else _traceSource.TraceEvent(_buffer.EventType, id, _buffer.Text) End If I could do this for all the tracing, but then all entries in the EventLog would be listed with Level = Information. So I want to be able to specify the severity of the trace message, but I can't find any method on the TraceSource or the TraceListeners that allows me to do this. As far as I can tell, TraceListener has these options for writing to it: Write() WriteLine() TraceData() TraceEvent() TraceTransfer() The last 3 allows for providing a TraceEventType (which correctly labels the EventLog entries, but the resulting output to the console and the log file then includes the prefixes and ends up like this (for example): Bootstrapper Warning: 0 : Failed to validate assembly Is there a way to override how the ConsoleTraceListener and TextWriterTraceListener format their output to not include this header, while at the same time being able to tag the entries with a TraceEventType (for the EventLog)? This is the best I have come up with so far: For Each listener As TraceListener In _traceSource.Listeners If listener.GetType Is GetType(ConsoleTraceListener) OrElse listener.GetType Is GetType(Text
