Sort Array in Descending Order in Windows Store App

Introduction

In my previous article I described Sort Array in Ascending order and this article describes how to sort an array in descending order. It is very simple by just using math reverse. Here I have first sorted the array in ascending order and then reverse the array.

Use the following procedure to create it.

Step 1

First of all you must 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="array_sorting.MainPage"

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

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

xmlns:local="using:array_sorting"

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 array_sorting

{

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

int[] arr = new int[5];

int i = 0;

private void button1_Click(object sender, RoutedEventArgs e)

{

if (textbox1.Text.Length > 0)

{

if (i < arr.Length)

{

arr[i] = int.Parse(textbox1.Text);

i++;

textbox1.Text = " ";

}

else

{

text1.Text = "Sorry Array can contain only 5 element";

}

private void button2_Click(object sender, RoutedEventArgs e)

{

foreach (int a in arr)

{

text2.Text += a + " ";

}

private void button3_Click(object sender, RoutedEventArgs e)

{

Array.Sort(arr);

Array.Reverse(arr);

foreach (int a in arr)

{

text3.Text += a + " ";

}

Step 4

Now Run your app.
