The best way to learn a new programming language to write a few simple programs and execute them.
A C# program basically consists of the following parts:
Namespace declaration
A class
Class methods
Class attributes
A Main method
Statements & Expressions
Comments
Lets start:-
using System; // System is a namespace
class Simple //Declaration of a class. Simple is as a C# <em>identifier</em>
{
public static void Main()
{
//Main method begins
Console.WriteLine("Welcome to C# world..!!");
Console.ReadKey();
}
// main methods ends
}
C# supports a feature known as Using directives that can be used to import System namespace into the program.
