How to Find Leap Year in Windows Store App

In this article I am going to explain how you can check to determine if a specified year is a leap year or not. This article is created as a Window Store App in C# that determines whether a year is a leap year. For implementing this application I am using a simple XAML textbox that accepts the year in the form of input and a button to implement the BL logic.

To create the app use the following intructions.

Step 1

First of all you have to create a New Window Store Application.

Open Visual Studio 2012
"File" -> "New" -> "Project..."
Choose "Template" -> "Visual C#" -> "Windows Store app" -> "Blank App (XAML)"
Rename the application

Step 2

Now the project will be opened. Go into Solution Explorer and choose "MainPage.Xaml" for designing and "MainPage.Xaml.cs" to write the business logic.

Step 3

Write the following simple code in "MainPage.Xaml":

<Page

x:Class="App5.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:App5"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

</Page>

Step 4

Finally write C# code in "MainPage.Xaml.cs".

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
namespace App5
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
}
private void Button1_click(object sender, RoutedEventArgs e)
{
int y = Convert.ToInt32(tex1.Text);
if(y % 4 == 0 && y%100!=0|| y % 400==0 )

{

tex2.Text = "leap year";
}
else

{
tex2.Text = "Not leap year";
}
}
}
}

Step 5

Now Run your application.
