C# Program Structure

class Example
{
     - collection of members  // Static and Non-Static members

    static void Main([string[] args]) 
{
    - statements;
}

}

A C# program contains the following parts in it:-

• Declaration of Namespace
• Class
• Class members
• Main method    // Entry point of the program
• Statements and Expressions
• Comments

Sample Program :

using System;

class Example

{

static void Main(string[] args)

{

  Console.WriteLine("Welcome to Csharp Programming...!");

}

}

output: Welcome to Csharp Programming...!

Now let us learn various parts of the above program :

• using System in the first line is used to include the System namespace in the program. This namespace has Console class which has many methods like writeline(), readline() etc.. 
• class is collection of members.
• Main() is the point from where the execution starts.
• Console is a class present under System namespace.
• WriteLine is a method defined under console class. Moreover, it is a printing statement.
