Palindrome Number in Windows Store App

In this article I describe Palindrome Numbers in a Windows Store app. We will begin with a brief explanation of Palindrome Numbers.

Palindrome Number

A number that is equal to itself when reversed is called a Palindrome Number.

Example: 121, 131, 11 etc.

Now let us create a Palindrome Number app in Windows Store.

Step 1

First of all you have to create a new Windows Store Application.

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

Step 2

Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):

<Page

x:Class="Palindrome_number_app.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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

xmlns:local="using:armstrong_app"

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 3

Now write the following C# code for the button within "Mainpage.Xaml.cs".

using System;

using System.Collections.Generic;

using System.IO;

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 Palindrome_number_app

{

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 num = Convert.ToInt32(Textbox1.Text);

int rev = 0;

int num1 = num;

while (num > 0)

{

int r = num % 10;

num = num / 10;

rev = rev * 10 + r;

}

if (rev == num1)

{

text2.Text = "Palindrome numbers";

}

else

{

text2.Text = "Not Palindrome numbers";

}

Step 4

Run the Palindrome app.
