|
 |
Hello People.
Still trying to learn c#, having a lot of fun. Thou I still have some questions. One of them is this:
When you normally declare a class variable you also use the new keyword to create it on the heap and call its constructor. But what happends when you ignore the declaring of the variable?
so instead of doing this:
| Code: | | ExampleClass myClass = new ExampleClass(); |
you just do this instead:
| Code: | | new ExampleClass(); |
Does it just create the constructor, run its code and just wait for the garbage collector to remove it again?

Yes, that is exactly what happens. But we can take an example of a class that runs a new thread in its constructor, so the garbage collector won't actually collect the object until that thread is done. And so on, that is just one example.

I love the garbage collector in C#.NET... You basically don't have to bother with that crap as long as your code is correct.

Thanks for the help.
I mentioned some other questions, hopefully someone will help me get some answers.
One of them is not necessary C# specific, but more a question on programming in general. While reading my books on programming, I've noticed that that when the programs gets bigger I sometimes get a little lost trying to figure out whats going on. These programs are pre-programmed for the most part, so I haven't dipped my fingers into all of areas of the program.
What I'm asking is, what is your usual way of reading other peoples code? Starting at the Main method and just working through the program from there? This seems good until I hit programs with Inheritance and/or interfaces.

There's no methodology for understanding other people's code. You just gotta spend time studying it. Personally, I study each of the smaller classes first, then see how they are used and tied together. But you can also start from the Main method as well. There really is no methodology behind it

Yes but when it bugs out (which is rare, but it does happen), you're fucked trying to track down what is happening!

I start from the Main (or comparable high level function), and F12 my way into methods and classes as I go. It doesn't have to be in the order code appears though, usually I go to what I consider more complex, then do a quick review of what is more basic.
This works for me, but sometimes going back to a code I have read, after reading another section is needed.
