Enumerable.Empty() vs new ‘IEnumerable’() – what’s better?

Enumerable.Empty<T>() vs new ‘IEnumerable’<T>() – what’s better?

Reading Microsoft documentation when we have all that stackoverflow questions with answers usually seems a waste of time. And as a typical, lazy programmer I admit that (much too often) I agree with that sentence ?. But today I decided to check how Enumerable.Empty<T>() works and wasn’t satisfied with the knowledge I got. I started digging a little bit deeper and wasted some of the precious beauty-sleep time so if you want to know what’s happening when you add an element to an empty collection, let me tell you a story of today’s night.
No, not that story, you sick head! Continue Reading

C# stuff nobody told you – delegate is a class! And there is a good reason for that!

Have you ever wondered why blue screens of death happen so rarely, nowadays? Of course, we can thank Microsoft for this but the way they fixed this problem is not so obvious! According to Marino Posadas (and his book Mastering C# and .Net Framework) back in 2010, Microsoft made an analysis of this topic and they came to the conclusion that the 90% (wow!) of the blue screens were caused by drivers! So, Microsoft made manufacturers to follow the Hardware Compatibility List. That somehow solved most of the problem but what with the rest 10%? Most of them was due to the… Continue Reading

C# Delegates – a fairy tale about when (and how) to use them.

Many people neglect C# delegates because they cannot find a reason to use them. On the other hand, there is (rather small) group of people who overuse delegates in code that could be easily replaced by literal method call. So when should we use delegates? Well, they show their real power in situations when we need a mechanism to easily switch from one logic to another, without changing our application’s core code. Continue Reading

C# attributes you should know #2: [DebuggerStepThrough] and [DebuggerHidden]

Last time I wrote about C# attribute DebuggerTypeProxy that helps us customize the way we display our type’s data while debugging. Today I would like to introduce you to the world of attributes that helps you skip some parts of code while debugging. Most of the C# programmers probably know them well, but I realized that only a few can tell the differences between them. So, ladies and gentlemen, let me introduce you the DebuggerStepThrough and DebuggerHidden. Continue Reading

C# attributes you should know #1: [DebuggerTypeProxy]

[DebuggerTypeProxy] is very useful attribute when you have a class that inherits from another class and that one inherits from another one, and some of the classes contain collections of items and hundreds of properties that in fact are not important to you… Strictly speaking, when displaying class’ members while debugging makes you feel like quitting the job.
