Palindrome String in Windows Store App

In my previous article I described Palindrome Numbers. But in this article I describe Palindrome Strings. So let us first of all understand what a Palindrome String is.

Palindrome String

A string that is equal to itself reversed is called a Palindrome String. Just like the Palindrome number.

Example: String nitin is equal to itself reversed.

Use the following procedure to create the Palindrome String app.

Step 1

First of all you have to create a new Windows Store Application using the following:

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_string.MainPage"

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

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

xmlns:local="using:palindrome_string"

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_string

{

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

private void Button1_click(object sender, RoutedEventArgs e)

{

string str = Textbox1.Text;

string revstr = "";

for (int i = str.Length - 1;i>=0 ; i--)

{

revstr = revstr + str[i];

}

if (str == revstr)

{

text2.Text = "Palindrome";

}

else

{

text2.Text = "Not Palindrome";

}

Step 4

Now Run Your app.
