    <p>Ok so after reading danben's answer on this <a href="https://stackoverflow.com/questions/2230180/whats-log4j-actually-doing-when-we-turn-on-or-off-some-log-places">post</a>, I guess I'm convinced of the need for writting this kind of code, atleast in a lot of cases. My managers seem to be agreeing too.</p> <pre><code>if (log.IsDebugEnabled) log.Debug("ZDRCreatorConfig("+rootelem.ToString()+")"); if (log.IsInfoEnabled) log.Info("Reading Configuration . . ."); </code></pre> <p>The problem with it is it bugs the heck out of me seeing all these if statements placed everywhere just to do a simple log statement. </p> <p>My question is, how might we refactor this into a class without reproduceing the performance problem of having to evaluate the arguments to the log method?</p> <p>Simply putting it in a class as a static method doesn't help, because when you pass the Object message it still has to evaluate the argument:</p> <pre><code>public class LogHelper { public static Info(ILog log, Object message) { if(log.IsInfoEnabled) { log.Info(message); } } } </code></pre> <p>C# apparently doesn't support forcing a method to be inline, so that solution isn't available. MACROs are not supported in C#. What can we do?!?!</p> <p>UPDATE: Thanks for the replies, I have not forgot about this one; it's just low priorty on my list right now. I will get to it and award the answer once I get caught up a bit. Thanks.</p> <p>Another UPDATE:<br> well ... I still haven't look at this closly yet, and both of you deserve the correct answer; but I awarded Tanzelax the answer because I agree, I think they will be automatically inlined. The link he posted does good job of convincing me I shouldn't worry too much about this right now, which is also good lol. I'll still look at those lambda things later. Thanks for the help!</p>

    1. COHave you tried NLog? IMO NLog tends to be cleaner than Log4Net.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
