c# - Why can't I call my WriteLogDataToDb method? -

i'm making user inactivity logger internal application @ work, , i'm having trouble writing consumed messages mysql database, when try call method writes messages database, throws error: 'accesseye.logdata' 'type', not valid in given context

any , appreciated, it's windows forms project topshelf service being used rabbitmq consumer, forward messages database mentioned =]

you passing type parameter writelogdatatodb() method, when expected instance of accesseye.logdata.

i don't know initialize variable, "fix" (you initializing default instance suggested code) issue must change piece of code.

program.bus.subscribe<accesseye.logdata>(queue,         (msg, messagerecinfo) => task.factory.startnew(() =>        {             writelogdatatodb(new accesseye.logdata());        })); 

note don't know constructors defined accesseye.logdata type, know.

at other hand, suppose 1 of parameters lambda expression instance of required type.

what of suscribe() method of type accesseye.logdata?

edit:

as op says in comment, solution replace original code code snippet:

program.bus.subscribe<accesseye.logdata>(queue,     (msg, messagerecinfo) => task.factory.startnew(() =>    {        var data2 = logdatafactory.collectdata();        data2.eventtype = accesseye.userstateevents.logon;        writelogdatatodb(data2);    }));
