Simple Question to using a object instance

[MarkPhB]

Hi, is there a problem when i use an object instance like this ?

( new AnyClass() ).SomeMethode();

instead of

AnyClass ac = new AnyClass();
ac.SomeMethode();

The compile dont have a problem with it but i asking me whether it is good or bad :confused:

Hello, No problem, but: I wouldn't want to see code like this in one of my projects. If it makes sence to do this:

,there is not need to use a class at all, I guess. You could simply use a static method.

All the best, Martin

Thanks for the answer =) i use this sometimes when i have a class with have a methode that i need only one time. Like

( new Form1() ).ShowDialog()

or

( new RNGCryptoServiceProvider() ).GetBytes( randomBytes );

Hi, I don't like your ( new Form1() ).ShowDialog(); since Form1 (assuming inheriting from Form) offers a Dispose() method which you should call once you don't need the Form1 instance any longer. :)

this weeks tips: - make Visual display line numbers: Tools/Options/TextEditor/... - show exceptions with ToString() to see all information - before you ask a question here, search CodeProject, then Google

Very Good point Luc! I would use a "using" block for that!

All the best, Martin
