NLog callback possible? -

i in process of converting home grown logging system nlog , wondering if there way add event logger or otherwise support mechanism when log message can callback final formatted message , loglevel. use send server messages connected client.

thx

this mcve of talking in comments. create target accepts callback functions:

[target("myfirst")] public sealed class myfirsttarget : targetwithlayout {     private readonly action<string>[] _callbacks;      public myfirsttarget(params action<string>[] callbacks)     {         _callbacks = callbacks;     }      protected override void write(logeventinfo logevent)     {         foreach (var callback in _callbacks)         {             callback(logevent.formattedmessage);         }     } } 

configure nlog use target. programmatically since callbacks passed in constructor. can configure target in nlog.config, target need singleton can register callbacks in code.

class program {     public static void main()     {         logmanager.configuration.addtarget("myfirst", new myfirsttarget(s => debug.writeline(s)));          var logger = logmanager.getcurrentclasslogger();         logger.debug("test");     } } 

with no other nlog configuration (copy code empty project , add nlog nuget package), emit message debug window.
