How to Handle Console Key Press Events in C#?

Console Key Press Event Handling in C#

In console applications, capturing keystrokes requires an approach different from traditional GUI applications. In C#, the following code snippet allows you to register for key press events in a console application:

public class Program
{
    public static void Main()
    {
        // Read keystrokes until the 'X' key is pressed
        ConsoleKeyInfo keyinfo;
        do
        {
            keyinfo = Console.ReadKey();
            // Display the pressed key
            Console.WriteLine(keyinfo.Key + " was pressed");
        }
        while (keyinfo.Key != ConsoleKey.X);
    }
}

Explanation:

• Console.ReadKey(): Captures the next key pressed by the user without displaying it on the console.
• The key press is stored in a ConsoleKeyInfo structure, providing access to the key that was pressed.
• The do-while loop continues reading and displaying key presses until the 'X' key is pressed, which exits the loop.

Note: For console applications to capture key press events, they require focus. If your application does not have focus, it will not receive key press events.
