Good afternoon guys,
I've been studying C #, I've come to see about the using directive, and in the C # documentation it says it has 3 uses, one of 3 usage items says it's meant to create an alias for a namespace or a type, but what would it be an alias directive and what is its usefulness? I researched and did not find out about.
It serves to avoid ambiguity. Imagine the following situation:
using System.Windows.Forms;
using System.Windows.Input;
In these two namespaces there are classes in common. How would the compiler know which class you want? To resolve this and still use using you can create a nickname ( alias ):
using Input = System.Windows.Input;
So, you could access, for example: Input.ModifierKeys not generating any ambiguity since it knows that Input refers to System.Windows.Input .
Some also believe that this is good practice, this I can not answer correctly.
