The user does not need to press Enter afterwards for the method to return. ReadKey waits for the user to press a key, or a key combination including one or more of the control, alt and shift keys. For this type of operation you can use the ReadKey method. For example, you might ask a Yes/No question and wait for the user to press either Y or N in response. Sometimes you'll only want the user to provide a single key press. The final Console.ReadLine waits for Enter to be pressed before the program exits.Ĭonsole.WriteLine("Enter a line of text, then press Enter") Ĭonsole.WriteLine("You typed: ", input) Ĭonsole.ReadLine() Reading a Single Character To show that the text was correctly received it is echoed back to the user. The entered information is obtained using ReadLine and stored in the string variable named, "input".

The code uses WriteLine to prompt the user to enter some text. We can demonstrate this very easily by adding the following code to the Main method of a console application. At this point the program continues from the command following the ReadLine. When the user presses Enter, the buffer's content is returned as a string. As the user types, the buffer is updated. ReadLine creates a buffer that can receive up to 254 characters. To receive this type of input, you can use the ReadLine method. This might represent some information to be processed or a command that your program understands and can execute. It's common to request a line of text from the user. The members include two important methods for accepting direct input from the user. The Console class contains a set of static methods and properties that allow you to interact with the user in a console application. With console applications primary input is via the keyboard, either by requesting lines of text or detecting individual key presses. Console applications are ideal for small tools and utilities where a graphical user interface is unnecessary.
