namespaces

While going through some legacy code today I discovered that you can declare a C# class without placing it in a namespace (in this scenario I have an ASP.NET WebForms application and some of the web forms are not declared within any namespace).

A GetType() on such a class returns a type where the namespace property is set to null.

I did not know that this was allowed - can anyone suggest why it would be desirable to have a class that is not declared within a namespace?

Dynamic Type to do away with Reflection

One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
