yes, if the documentation for a particular class says so. Otherwise no.
The typical .NET class does that, as you well know.

I found this interesting piece on the msdn site -
"A call to a static method generates a call instruction in Microsoft intermediate language (MSIL), whereas a call to an instance method generates a callvirt instruction, which also checks for a null object references. However, most of the time the performance difference between the two is not significant."
This is contrary to the belief that static methods can improve performance in certain situations.
So I suppose it's just a matter of usage really.

Why contrary? Sounds like it says static methods are faster. Granted the difference is not significant most of the time (i.e., it is significant some of the time).

when is that local variables are created and destroyed ,C#?
thanks.

You really need to buy this book[^] and read it. The point of the forums is not to teach people the basics of the language - the forums are here to help people with specific problems they may have.

What difference does it make?
|
|
|
|

it may be important when a method needs huge amounts of local variables: it may work well when they get allocated and freed by the smallest code block that contains them, it may throw a StackOverflowException when all of them get allocated upfront.

Isn't that going to use more stack space? Return addresses, and so forth...

Yeah, well, you could delegate some data to local variables in a different method, executed by some other thread. So basically implement an in-stack database, using Invoke to call on a single GetSet() method. But then that may be over-engineering the situation a bit.

I need some quick direction, how to - overview. I am relatively new to C# and Windows Form Programming but excited and interested in consuming everything I can. I need some direction for my research and design.
I have a panel control.
Within the panel control I have 4 Text Boxes, a DataGridView, a few labels etc...
I have an xml file source.
I have a main source windows form.
I want to have a drop down box on the Windows Form that has a list of items from the xml file.
Once I select the item from the down box I want to copy (instantiate) the panel with all of the controls within the panel, and then populate them with the rest of the data from the xml dataset already loaded.
I have done all of the code up to the instantiating and copying the panel with its controls...
Is there a better way to do this? keywords i can research, a little direction would be so helpful! Thanks!

tricky question... indeed... but I can think that if you want to transmit data in C#, even before starting you need to make sure you have a computer connected to a network (can be internet), and the only way I think you can transmit data over is with TCP packets... isn't that a little advanced for homework???

Loads of them - how complex do you want to go? How is your data arranged?
