Global keyword usage for C # in ASP.net

The following code:

The code is as follows	Copy Code
using System; using System.Collections.Generic; using System.Linq; using System.Text;   Namespace Globalfunc {     class program     {  &N bsp;      static void Main (string[] args)         {             System sys = new system ();             global::system.console.writeline ("Global .");             Global::system.console.readkey ();        }    }     public class System {}

 
Although a System namespace is using, there is also a public class system{below ...} class, so that if you use System.Console.WriteLine directly, you will get an error, because you will find the nearest system class, there is no Console in the system class. So if you need to use it, you need to use Global::system.console.writeline as above, because classes that use the global tag start looking globally, and my understanding is to look inside the System class from the outermost.
