How to write simple C# code?
Understand the C# programming structure?

Well, you have understand where to and how to execute your program. In this section you will see the detailed explanation of short C# program. It will help you to implement your logic into program. So, carefully study the code and get the basic C# programming structure.

Each program requires three important steps to do work. It is Input, Process and Output. It is the basic concept of almost all the programming language. It is also known as I-P-O cycle. The program requires some input from the user. Next, the program processes the input with programming language and finally shows the output.





  • Consider the simple C# code, in which you will enter your name and your name will be displayed with some text message in command prompt.

    string name; //Variable for storing string value
    It is a string variable that stores value input by user. A variable is a symbolic name of special data types that is used to store value in memory temporarily. Here, name is variable of string data types.


    Console.WriteLine("Please Enter Your Good Name");

    Console.WriteLine() : It is used for displaying message on the console. Console.ReadLine() : It is used for accepting user input.
