ExampleC#

using System;

class Program
{
    static int Divide(int a, int b)
    {
        if (b == 0) throw new ArgumentException("Cannot divide by zero");
        return a / b;
    }

    static void Main()
    {
        try
        {
            Console.WriteLine(Divide(10, 2));
            Console.WriteLine(Divide(1, 0));
        }
        catch (ArgumentException e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
        finally
