Runtime errors occur at the time the program executes and can't be corrected. A programmer can, however, take preventive measures while coding the program, to handle runtime errors with the help of the try, catch, and finally keywords.

using System;
using System.Collections.Generic;
using System.Text;
namespace exception
{
    class Program
    {
        public static void Main()
        {
            int x = 0;
            int intTemp = 0;
            try
            {
                intTemp = 100 / x;
                Console.WriteLine("Not executed line");
                Console.ReadLine();
            }
            catch (DivideByZeroException de)
            {
                Console.WriteLine("DivideByZeroException");
                Console.ReadLine();
            }
            catch (Exception ee)
            {
                Console.WriteLine("Exception");
                Console.ReadLine();
            }
            finally
            {
                Console.WriteLine("Finally Block");
                Console.ReadLine();
            }
            Console.WriteLine("Result is {0}", intTemp);
            Console.ReadLine();
        }

        }
    }
