The difference about namespace between VB.NET and C#

[ad]

Is there any difference about namespace between VB.NET and C#.



All functions in c# must include in a namespace.

Why I can't find namespace in the files .vb .

How VB.NET implement the concept of namespace

Ad,

No! As namespace is a CLR construct used to groups types.

Why I can't find namespace in the files .vb .

VB.NET projects normally set the Root namespace property under the Project
Properties dialog.

While C# normally leaves the Root namespace property blank under the Project
Properties dialog.

Hope this helps

Thank!
But, Why the vb project still can compile after I delete the root namespace
in the project properties dialog,
and I did not add namepace in the codes, so that there are no namespace in
my vb projec?

This will generate a namespace without a name.

Ad,
Namespaces are not required or as Herfried suggests you can have an unnamed
namespace. As namespaces are simply an organization feature to avoid name
collisions.

In other words in both C# & VB.NET you can leave the root/default namespace
blank, and not to include a namespace statement in the source files. In both
cases you will have an unnamed namespace in the generated assembly.

Doh! Technically C# uses a "Default namespace" that is used when adding new
types. Changing this default namespace does not change existing types.

Hope this helps
