Should namespace hierarchy reflect the folder hierarchy on the disk

[HalcyonWild]

I did try to search this in old posts, but could not find it.

I suppose it is ok to ask beginner level questions here, unlike other
groups, demarcated for beginners and experts.

Suppose I create a class in a namespace, MyNamespace.Trials.

Now, should I create a folder on the disk, like
c:\csprogs\MyNamespace\Trials and keep the generated files there. Or I
can keep them anywhere on the disk.

Also, once I tried making a simple geometry point class, and it would
not compile.

class CSPoint
{
int x;
int y;
//ideally should be double, in a 3d space,
//but just for testing sake, it is 2 ints in a plane

//getter and setter methods.
}

I needed to add a Main. Why is this so.

I come from a Java background.
Thanks.

HalcyonWild,

I tried using that heiarchical structure, but I found that it was overly
complicated for projects to reference each other in a solution.

I flatten the heiarchy, and have one directory for each distinct
namespace, so my solution directories will have the following project
directories:

Casper
Casper.Remoting
Casper.Drawing

And so on. In your case, you would have a MyNamespace directory, as
well as a MyNamespace.Trials directory. It will make it much easier as you
have more namespaces, and they start referencing each other.

Hope this helps.

There is no such technical restriction (you can keep them anywhere), but it
is widely regarded as a good practice and makes things easier to find.

Your project type was an executable, rather than a class library.
Executables need an entry point.

Thanks for the quick responses, Chris and Nicholas,

So as I understand it, it is not a restriction from the language side,
to maintain namespace hierarchy in the paths on the disk. But we do it
just for easy maintainability.

So I can keep all my .exe files at one place on the disk, even though
the namespaces are different. I should however maintain folder
hierarchy on disk for easy tracking. Please correct me if I am wrong.

I think that must be a compiler switch, to compile a .cs into a class
library rather than executable. Will look for it. Also Chris, I do not
have visual studio.net. I am using the cmdline compilers with the
framework.

Also, assemblies are something like jars, (from what I searched and
found, not really sure about this), and you normally name assemblies
like namespaces, as a good practice. More questions on this later if I
have any problems. I will try this out.

Thanks.

As an afterthought, I think this is a great feature. No need to take
care of classpaths, imports , package hierarchies on disk, like in
Java.

No one os your physical hardisk hierarchy and the other your logical
class heirarchy no relation
