svn commit: r1476902 - in /logging/log4net/trunk: log4net.build
src/Util/ILogExtensions.cs src/log4net.vs2008.csproj
src/log4net.vs2010.csproj
Author: dpsenner
Date: Mon Apr 29 06:27:24 2013
New Revision: 1476902
URL: http://svn.apache.org/r1476902
Log:
LOG4NET-290 added an ILog extension that wraps the most common logging statements in a central place
Basically statements like these:
if (log.IsDebugEnabled) log.DebugFormat("x: {0}", 123)
can now be shortened to:
log.DebugExt("x: {0}", 123)
