Console.CursorVisible in C#

Introduction:

In C#, the Console.CursorVisible property plays a vital role in controlling the cursor's visibility within the console window. This article aims to provide a comprehensive understanding of Console.CursorVisible, covering its syntax, parameters, examples, and common use cases.

Syntax:

The syntax for accessing and modifying the Console.CursorVisible property is straightforward:

Console.CursorVisible = true; // Show the cursor

Console.CursorVisible = false; // Hide the cursor

Parameters:

  • True: It indicates that the cursor should be visible.
  • False: It indicates that the cursor should be hidden.

Examples:

Let's delve into some practical examples to grasp the usage of Console.CursorVisible:

Showing the Cursor:

Console.CursorVisible = true;

Console.WriteLine("This is a visible cursor.");

Hiding the Cursor:

Console.CursorVisible = false;

Console.WriteLine("This is an invisible cursor.");

Use Cases:

Understanding when and how to use Console.CursorVisible is crucial for various scenarios, such as:

1. Enhancing User Experience:

  • In applications where user interaction happens primarily through the console, showing or hiding the cursor at appropriate times can enhance the user experience.
  • For instance, in a text-based game, we might want to hide the cursor during gameplay to prevent distractions.

2. Custom Console Interfaces:

  • Controlling the cursor's visibility can help create a polished look and feel when creating custom console interfaces or menus.
  • For instance, hiding the cursor while displaying information or prompts in a command-line utility tool can give a cleaner appearance.

3. Animated Graphics:

  • Console applications often simulate simple graphics using characters. Managing the cursor visibility can be crucial for creating smooth animations.
  • By hiding the cursor during animation rendering, you can avoid flickering and provide a more immersive experience.

Example: Toggling Cursor Visibility

This code demonstrates how to get the current cursor visibility, toggle its state, and display the updated value:

using System;

class Program

{

    static void Main(string[] args)

    {     

        bool isVisible = Console.CursorVisible;   

        Console.WriteLine("Current Cursor Visibility: " + isVisible);

        Console.CursorVisible = !isVisible;

        Console.WriteLine("Cursor Visibility Toggled to: " + Console.CursorVisible);

    }

}
