C# Lesson 1: Reply the Greeting

In this lesson, we would like that

1. The console window prompt the user to type their name.
2. The program capture their input as a string/text.
3. The program reply backs with the greeting.

Here we go!

Code the following (code in copy-able text is available below)

Press F5 to build and run...

Type you name as prompted, press Enter..

Let us now analyze the code

• We have used Console.ReadLine() to read input from user.
• We stored user input in a variable of string type. String variable are used to store and manipulate plain text.
• String concatenation is done by the plus "+" operator as shown in the example.

Here is the code in copy-able text

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace MyApp1

{

    class Program

    {

        static void Main(string[] args)

        {

            // write to the console window

            Console.WriteLine("Hello, May I know you name: ");

            // capture user input as string and store in variable called name

            string name =Console.ReadLine();

            // write to the console window

            Console.WriteLine("Welcome to you "+name+", Have a nice day!");

            // read line from user to avoid auto-window closure

            Console.ReadLine();

        }

    }

}
