Respond to the prompt by entering a name and pressing the Enter key. ![]() This syntax is referred to as interpolated strings. The expression value is inserted into the string in place of the expression. The dollar sign ( $) in front of a string lets you put expressions such as variable names in curly braces in the string. Alternatives are \n in C# and vbCrLf in Visual Basic. Finally, it displays a prompt in the console window and calls the Console.ReadKey(Boolean) method to wait for user input.Įnvironment.NewLine is a platform-independent and language-independent way to represent a line break. And it displays these values in the console window. It also retrieves the value of the DateTime.Now property, which contains the current local time, and assigns it to a variable named currentDate. It stores this string in a variable named name. This code displays a prompt in the console window and waits until the user enters a string followed by the Enter key. In Program.cs or Program.vb, replace the contents of the Main method, which is the line that calls Console.WriteLine, with the following code: Console.WriteLine("What is your name?") Ĭonsole.WriteLine($"Press any key to exit.") Press any key to close the console window.Įnhance the application to prompt the user for their name and display it along with the date and time.

Press Ctrl+ F5 to run the program without debugging.Ī console window opens with the text "Hello, World!" printed on the screen. But it's available in C# 10, and whether you use it in your programs is a matter of style preference. Most existing C# programs don't use top-level statements, so this tutorial doesn't use this new feature. In the latest version of C#, a new feature named top-level statements lets you omit the Program class and the Main method. Any command-line arguments supplied when the application is launched are available in the args array. Main is the application entry point, the method that's called automatically by the runtime when it launches the application. The code defines a class, Program, with a single method, Main, that takes a String array as an argument. If the language you want to use is not shown, change the language selector at the top of the page. The code is in the Program.cs or Program.vb file: namespace HelloWorld The template creates a simple application that displays "Hello, World!" in the console window.
