Multiple classes in a single .cs file - good or bad? [duplicate]

Answer 1

Logically its depend on your scope of application. But Normally best practice to do coding in seperate class (New File , new class )

Splittting files will be more sensible.Because industries follow ths standards...

Answer 2

For the sake of making things simple, you should probably put them in different files. I can't think of any advantages of keeping them in the same file.

Answer 3

When designing classes we respect the Single Responsibility Principle. Reading code becomes a lot easier if its shape follows its semantics, hence splitting files by class is sensible.

However if there are inner classes it makes sense to keep them in the same file

Answer 4

Simply say good practice is one class from one file. BUT if your application is quite small you can use several classes in one file.

Answer 5

It depends about your application. If it is a big application, I think that isn't good. Data must be very organized.

I think that is better to keep them in different files.

But, if you are working for a small application, it is good to keep them in same file.

Hope that I helped you.
