8. Exceptional Handling
Exceptional Handling Berlaku apabila user melakukan kesalahan dalam menginput. Dalam Contoh dibawah, bila user menginput huruf atau kata, maka program akan menampilkan pesan error.
using System;
namespace Exceptional_Handing
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
int a,b,c;
try
{
Console.Write("Input Nilai Pertama: ");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Input Nilai Kedua: ");
b = Convert.ToInt32(Console.ReadLine());
c = a * b;
Console.WriteLine("{0} * {1} = {2}",a,b,c);
Console.ReadLine();
}
catch
{
Console.WriteLine("Maaf, Anda Salah memasukkan Input");
Console.ReadLine();
}
}
}
