    LYL Leep Year Lister.

    Hi this is a small little console project to list leap years between two different dates.
    Very simple to use enter a starting date and an ending date. Hope you find it us full.

    csharp Code:
    1. using System;
    2. using System.Collections.Generic;
    3. using System.Linq;
    4. using System.Text;
    5.  
    6. namespace LYL
    7. {
    8.     class Program
    9.     {
    10.         private static bool IsLeapYear(int year)
    11.         {
    12.             //Check for leap year.
    13.             if ((year % 4 == 0 && !(year % 100 == 0 && !(year % 400 == 0))))
    14.                 return true;
    15.             return false;
    16.         }
    17.  
    18.         static void Main(string[] args)
    19.         {
    20.             int _startY = 0;
    21.             int _endY = 0;
    22.             int I = 0;
    23.  
    24.             Console.WriteLine("+------------------+");
    25.             Console.WriteLine("+ Leap Year Lister +");
    26.             Console.WriteLine("+ By Ben           +");
    27.             Console.WriteLine("+------------------+");
    28.  
    29.             try
    30.             {
    31.                 Console.Write("Enter starting year: ");
    32.                 _startY = int.Parse(Console.ReadLine());
    33.                 Console.Write("Enter ending year: ");
    34.                 _endY = int.Parse(Console.ReadLine());
    35.             }
    36.             catch
    37.             {
    38.                 return;
    39.             }
    40.  
    41.             //Print out years
    42.             for (I = _startY; I < _endY + 1; I++)
    43.             {
    44.                 //Test for leap year.
    45.                 if (IsLeapYear(I))
    46.                 {
    47.                     //Was leap year.
    48.                     Console.WriteLine(I + " is a leap year");
    49.                 }
    50.                 else
    51.                 {
    52.                     //Was not a leap year
    53.                     Console.WriteLine(I + " was not a leap year.");
    54.                 }
    55.             }
    56.         }
    57.     }
    58. }

    I know this isn't code it better, but instead of using a try/catch to check whether a user has input a valid integer, you should really be using .TryParse. If, at any time, you can handle an error (and actually do something about it) without using an exception, you should.
