How to Efficiently Read Integer Input from the Console in C#?

Efficiently Getting Integer Input in C# Console Apps

This guide shows you the best way to read integer input from the console in your C# programs. Using Convert.ToInt32() is far more efficient and straightforward than character-by-character conversion.

Here's a practical example: Imagine a program presenting menu options to the user. The following code snippet demonstrates how to get the user's integer choice:

<code class="language-csharp">Console.WriteLine("1. Add account.");
Console.WriteLine("Enter your choice: ");
int choice = Convert.ToInt32(Console.ReadLine());</code>

Console.WriteLine() displays the menu, and Convert.ToInt32(Console.ReadLine()) reads the user's input, converts it to an integer, and stores it in the choice variable. This provides a clean and effective method for handling numerical user input in your C# console applications.
