How to use EPiServers CMS log functionality to create your own log messages.
Create a logger
Start adding log4net as a reference for yor project.
using log4net;
public class MyClass
{
private static readonly ILog _log = LogManager.GetLogger(typeof(MyClass));
Write a debug message to the log
if (_log.IsDebugEnabled)
{
_log.Debug("Test logger");
}
Design tips: Always check if the logger is enabled before doing a lot of stuff.
Otherwise the debug code is going to slow your application down even if it’s not enabled.
Write an error message to the log
try
{
...
}
catch (MyException ex)
{
_log.Error("Can't execute test code, because", ex);
}
Design tips: Never leave a catch block empty, if the exception is handled some
other way please write a comment about this in the block.
