Remarks

An instance of this class can be used either standalone or as a System.Diagnostics.TraceListener. The static methods Systems.Diagnostics.Trace.Write() and Systems.Diagnostics.Trace.WriteIf() most naturally fit the Linux syslog facility.

Example

Copy

var log = new IO.Objects.SimpleIO.syslog.Logger();
log.Note("Hello, Syslog!");

System.Diagnostics.Trace.Listeners.Clear();
System.Diagnostics.Trace.Listeners.Add(log);
System.Diagnostics.Trace.Write("Hello, Trace!");
