Let's take a look at some code that handles user input. It can cause issues if you store the information in a database, but we'll assume that you're just asking for input, performing a calculation, and then displaying the output to the user. If the user decides to close the program, it does not crash the machine. The user could close the application, which stops execution as well, but you assume in your code that the user will send some data for you to process. This statement stops execution of the application and waits for the user's input. The second statement you need is the input statement. Both the prompting statement and the resulting output are both a form of console output. The numbers are then added together and the result is displayed back to the user. You display a prompt asking the user to enter two numbers. For instance, you can create a simple calculator with a console application. It also takes the calculated input and displays some information back to the user. This statement prompts the user for what must be entered. The first statement is the output statement. We'll discuss input from web applications in later chapters.Ĭ# requires two types of statements when you want to work with console input and output. Most beginner programmers learn how to deal with user input using the console, because these applications are the easiest to set up and configure. These applications use the Microsoft command line to display information and take user input from the keyboard. The simplest C# program is a console application. This article focuses on user input, how you can handle different data types, and returning a response to the user. You work with user input in console applications, local desktop applications, or your website pages. In almost any program, you need to handle user input. User input is any click command, text from a keyboard, or entry in a form. Most programs don't just run and perform a function without any type of user input.
