C# coalesce operator

Damn Microsoft! I finally thought I had my thick head wrapped around C# when they decide to come out with a boatload of new features to further confuse, err, I mean enhance things.

I was quite happy to read that they added a coalesce operator to C#. For those of you who use Sql Server on a regular basis, you’re probably quite familiar with this function. What it does is allow you to pass a list of values, and will return the first non-null value.

For instance, in previous versions of C# we might have code that looks like this :

After running this, the string “brian” gets outputted to the console. We can now rewrite this a little cleaner with the new coalesce (??) operator :

After running this, you’ll see we get the same results. Thanks again to the C# team for giving me the capability to make my code even more unreadable 😉

  1. Ha, your right. Learning Ruby at the moment (wish me luck) and this all finally makes sense. I’d have to agree, its hard to understand the concept of what’s going on thanks to Microsoft’s new “feature.” I don’t think that even a //comment can fix that there buddy ;-).
