2. using System;
3. // namespace. A class can belong to a namespace, or multiple classes can be in the same namespace;
4. // prevents class name conflicts. That is to say, different namespaces can have classes with the same class name. Of course, in standard code, namespaces can organize class levels,
5. // For example, the company name, project name, Module name, and project level are clear at a glance.
6. namespace YYS. CSharpStudy. MainConsole
7 .{
8. // C # is a pure object-oriented language. Classes are the basis of all code, and class keywords can define a class.
9. class Program
10 .{
11. // The Main method is the entry for project startup, and the program starts to run from Main. String [] args is a console parameter that is passed in from the console by the program running.
12. // the standard format is as follows.
13. // <summary>
14. // Main method

17. static void Main (string [] args)
18 .{
