Package of Log4net

There is no doubt that Log4net is incredibly powerful in journaling.

But there are also areas of criticism, such as the configuration is too cumbersome (here only to say that the log file log, like the logs logged in the database does not involve, the same as)

Have seen in the garden in the packaging of the package into a loghelper, less configuration I did not look carefully, but look at the following comments have said that the log records are still problematic

#8楼 2014-11-17 15:04 aeiiilowx Consult the landlord, using the package Loghelper class write log, in the configuration file layout, with%c,%f or%l to get the log class, The file and line numbers are always the corresponding line numbers for the Loghelper class, which means that the actual log classes, files, and line numbers are not properly obtained. Have you encountered this problem?

This problem I also met, feel uncomfortable, then gave up.

Yesterday suddenly want to solve this problem, say dry do it
