The Switch Statement

[Guffa]

Actually, if you have more than just a few case labels in a switch (four IIRC), it's implemented using a dictionary.

Despite everything, the person most likely to be fooling you next is yourself.

It depends on the situation. There are definitely situations where I've seen needless use of switch statements, and others that would have benefitted from a switch statement. If you find that you are switching on a specific property of a class a lot within that class then it can be an indication that you might want to refactor the code into a class hierarchy. Each derived class handles a specific case that was in the switch statement.

Wow what a mess. Fixed. Thanks

Yeah, more than five, as you showed back in July. I keep forgetting that. On the other hand, using your own Dictionary gives you more flexibility and the ability to use it in multiple places (if you can think of such a use).

As others said, switch statement has many benefits. So use it wisely. You should read something about method cohesion[^].

Switch case is better in performance than if-else-if ladder. While using switch case, compiler optimizes the code for the fastest execution. you can check this Url also: http://www.blackwasp.co.uk/SpeedTestIfElseSwitch.aspx[^]

Couldn't agree more. I have heard the "using construct X is really bad design" about more or less every construct in C/C++/C#, but they all have situations where they are just right, so use them where they make sense. (yes... even "goto"...)
