2-Reading and Writing to Console in C# || Urdu

Reading & Writing to Console 

•Writing to the Console.

•Reading from Console

• Two ways of Writing to the Console

–Concatenation

–Place Holder Syntax- most preferred 

 Example of –Place Holder Syntax- most preferred 

using System;

    class Program
    {
       
        static void Main()
        {
            Console.WriteLine("what is your First Name ?");
            string FirstName = Console.ReadLine();

            Console.WriteLine("what is your Last Name ?");
            string LastName = Console.ReadLine();
         
            Console.WriteLine("Your Name is {0}, {1} ", FirstName, LastName);

        }
    }

1 -Introduction To C Sharp || Urdu

In this session 

•Basic structure of C# program.

•What is Namespace.

• Purpose of Main method

Basic structure of C# program.

Below is given a sample program.
  In this program we have a 3 line of code 

using System;
    class Program
    {
        static void Main()
        {
           Console.WriteLine("Hello to the world");
           Main1();
        }
        static void Main1()
        {
            Console.WriteLine("Hello to Main !");
        }
    }

At the top , we have declared a namespace System in which Console class is residing.

within Console class WritLine() method is present. Which take an argument as a string and print the message to the out output console screen. 

Using system declaration

•A namespace declaration , Using System,  indicate that you are using the system Namespace.

•A namespace is used to organize your code and is a collection of classes , interfaces, structs, enums and delegates.

•Main Method is the entry point of into your application.
