C# 6 Exception Filters and How they are much more than Syntactic Sugar

[Sander Rossel]

You're right, it's actually F# :sigh:

My blog[^]

public class SanderRossel : Lazy<Person>
{
public void DoWork()
{
throw new NotSupportedException();
}
}

That's not F# either. :rolleyes:

If your actions inspire others to dream more, learn more, do more and become more, you are a leader.-John Q. Adams
You must accept one of two basic premises: Either we are alone in the universe, or we are not alone in the universe. And either way, the implications are staggering.-Wernher von Braun
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.-Albert Einstein

public void DoWork()
{
throw new NotSupportedException();
}

The exception object has been created - it's just that the examples on that blog post don't show it. You could easily do:

try
{
...
}
catch (SomeException ex) if (Log(ex))
{
}

This blog post[^] has a better example.

Keep guessing. When you get to C#, stop.

Ummm...wrong. If the Exception hasn't been created yet, how is the catch block going to know about it? The Exception HAS been created by the time the catch block and the filters start executing. Ever set a breakpoint on a catch in VS? Without the catch executing, you get a little tag you can click and see the, wait for it, Exception object!

You really want me to continue? :laugh: To tell you the truth I actually know what language I wrote my own signature in. I'm just messing with you guys :D

Dude, with the tpye and quality of a lot of the questions that show up around here, I wouldn't doubt someone doesn't have a clue about what they put in their signature.
