Namespaces

Hi Imar,

In (Chapter 5 Namespaces Pg. 184) you introduce namespaces and describe where the Page class lives.

In (Chapter 6 Creating Consistent Looking Websites Pg. 221) you describe using a BasePage inheriting from System.Web.UI.Page. And In later chapters you build on this idea and reference this BasePage.

In what namespace does IT(BasePage or MyBasePage) live? When you create classes in your project how do we know what their full names are?

Thanks.

Hi there,

The BasePage lives in the "root namespace" (which is ASP) since you haven't supplied your own namespace. The root namespace is an implicit namespace that Visual Studio / ASP.NET make available for web site projects. The same applies to your other classes such as the Calcualator so they can all see each other because they all live in the same implicit namespace.

If you put your classes in a namespace, their full names are Name.Space.ClassName.

What does MyBasePage refer to?

Hope this helps,

Imar

Interesting. So it resides adjacent to the root namespace "System"?
(
i.e.
System.Web
ASP.MyBasePage
)

How would you address it with it's full name?

The MyBasePage is the name of the template web form you have us create in Chapter 6, Pg. 227. It inherits from BasePage, which in turn inherits from System.Web.UI.Page. The BasePage class has two additional event handlers.

No, it resides in just ASP. System.Web is another namespace, with all the standard web-related .NET types.

MyBasePage is not a type; it's purely a temporary solution. BasePage is a type, and lives in the implicit ASP namespace.

Hope this helps,
