Namespaces and subnamespaces in C#

Question

begginers question about C#.

In every program I have to include several namespaces, like:

using System;
using System.Collections.Generic;
using Syste         


        

Answer 1

If you wanted access to a class in System.Text without the using statement, you would have to Text."Name of class/function" every time you wished to use it.

This way you can just call "name of class/function".

Not sure if you are a beginner, but that's the simplest way I can describe put it.

Answer 2

Just an added example to make you understand clearly.

A child Namespace cant be accessed by calling parent namespaces

Namespace Main  //only code and classes are accessible
{
  //code for Main Namespace
  Namespace subMain     //only code and classes are accessible
  {
     //code for subMain
     Namespace verySubMain  //only code and classes are accessible
     {
        //code for verySubMain
     }
     Namespace otherVerySubMain  //only code and classes are accessible
     {
        //code for otherVerySubMain
     }
  }
}
