Sort Array in Descending Order in Windows Store App


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):










    <Grid Background="Red">


            <RowDefinition Height="76*"/>

            <RowDefinition Height="46*"/>

            <RowDefinition Height="45*"/>

            <RowDefinition Height="42*"/>

            <RowDefinition Height="45*"/>

            <RowDefinition Height="514*"/>



            <ColumnDefinition Width="149*"/>

            <ColumnDefinition Width="287*"/>

            <ColumnDefinition Width="242*"/>

            <ColumnDefinition Width="688*"/>


        <TextBlock Text="Enter the Array Element" FontFamily="Arial" FontSize="20" FontWeight="ExtraBold" Grid.Column="1" Grid.Row="1"></TextBlock>

        <TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="1" VerticalAlignment="Top" Height="32" Width="175" HorizontalAlignment="Left"  />

        <Button x:Name="button1" Grid.Column="2" Grid.Row="2" Background="Yellow" Foreground="Black" Width="150" VerticalAlignment="Top" Height="35" Content="Insert" Click="button1_Click" ></Button>

        <TextBlock x:Name="text1" Grid.Column="3" Grid.Row="1" Foreground="White" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" ></TextBlock>

        <Button x:Name="button2" Grid.Column="2" Grid.Row="3" Background="Yellow" Foreground="Black" Width="150" VerticalAlignment="Top" Height="35" Content="Show" Click="button2_Click" ></Button>

        <TextBlock x:Name="text2" Grid.Column="3" Grid.Row="3" Foreground="White" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" ></TextBlock>

        <Button x:Name="button3" Grid.Column="2" Grid.Row="4" Background="Yellow" Foreground="Black" Width="237" VerticalAlignment="Top" Height="35" Content="Show After descending sort" Click="button3_Click" ></Button>

        <TextBlock x:Name="text3" Grid.Column="3" Grid.Row="4" Foreground="White" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" ></TextBlock>





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()




        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);


                    textbox1.Text = " ";




                    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)




            foreach (int a in arr)


                text3.Text += a + " ";






Step 4

Now Run your app.
