Using directives

[Dario1984]

Hi.

I'm trying to use the using directive like a typedef in C++. Can I re-write the following to be legal in C# in any way ?

.....
using UidListType = System.Collections.Generic.List<UidType>;
using BodyTableType = System.Collections.Generic.Dictionary<string, UidListType>;
using FunctionTableType = System.Collections.Generic.Dictionary<string, BodyTableType>;
....

In other words, can a Using directive be dependent on the Using directive above it ?

No, it's not intended to be used in that manner. There are two ways to use the [tt]using[/tt] keyword:

1. In class and namespace scope, the [tt]using[/tt] keyword allows you to import another namespace so that your code is more compact.

2. Inside methods, the [tt]using[/tt] keyword surrounds a block of code, and acts as a compact implementation of the IDisposable interface, to protect you from resource leaks.
