JJ TAM - LEARN C# QUICKLY AND JAVASCRIPT CODING PRACTICE EXERCISES: Coding For Beginners

Step 1: Open Visual studio Step 2: Go to File -> New -> Project. Select Console Application, give the project name as HelloWorld. Press OK. It creates a file Program.cs, with some default data. Update the program like below. using System ; namespace HelloWorld { class Program { static void Main ( string [] args) { Console.WriteLine("Hello World"); Console.WriteLine("Welcome To C# Programming........."); } } } Press CTRL + F5, it opens command prompt and show the strings that we passed to 'Console.WriteLine' method.

Lets analyze the program using System Above statement loads a names space System. Name spaces are used to organize the code. A name space is a collection of classes, interfaces, enums, structs & delegates. namespace HelloWorld Above statement gives the name space HelloWorld to this program. It is optional. using System ; class Program { static void Main ( string [] args) { Console.WriteLine("Hello World"); Console.WriteLine("Welcome To C# Programming........."); } } class Program Class is used to encapsulate methods and properties as single entity. using System ; class Program { static void Main ( string [] args) { Console.WriteLine("Hello World"); Console.WriteLine("Welcome To C# Programming........."); } } class Program Class is used to encapsulate methods and properties as single entity.

Ignore this for time being, I will explain about this in later posts. static void Main(string[] args) Main method is the entry point of your C# application. Application executions starts from here. Console.WriteLine("Hello World");
Above statement writes the message "Hello World" to console. Console is the class resides in name space System.
