C# .ToInt() Extension Method Example, C#

Language: Layout:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using Extensions;

// Calling extension method .ToInt() will convert a string to Int or throw the exception "Input string was not in a correct format."
// This works for internal variables and also Console.ReadLine();

namespace Rextester
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("32".ToInt() + "55".ToInt());
            //Console.WriteLine(Console.ReadLine().ToInt() + Console.ReadLine().ToInt());
        }
    }
}

namespace Extensions
{
    public static class StringExtensions
    {
        public static int ToInt(this string s)
        {
            int returnInt = 0;
            
            try
            {
                returnInt = Int32.Parse(s);
            }
