Looking for OnLog Event - log4net

Question

Dear Devs

I am using Log4net to produce different kind of logs and using RollingFileAppenders which rolls on a given size.

Now i have a new requirement that a log should be visible on a windows form therefore i am looking for some event that can be handled on each log entry within my application so i can display that particular log entry in my form as well.

Or there may be some appender which gives such functionality.

Any idea on this?

Answer 1

I'd suggest writing your own appender - it's really easy to do:

1. Create a class that inherits from AppenderSkeleton
2. Override the Append method

Simple!

Here is an example of a custom appender that updates a textbox.

Answer 2

As I suggest in this answer, you could set up a MemoryAppender and monitor log messages in memory. It does not expose an event but you could easily set up a timer that retrieves the latest messages.
