Swap the Value of Two Arrays in Windows Store App


In this article I will describe how to swap the values of two arrays. Previously, I have always swapped the values of variables. But now I have decided, why not interchange the values of two arrays. So in this article we are doing something different.

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">


            <ColumnDefinition Width="275*"/>

            <ColumnDefinition Width="321*"/>

            <ColumnDefinition Width="770*"/>



            <RowDefinition Height="60*"/>

            <RowDefinition Height="41*"/>

            <RowDefinition Height="42*"/>

            <RowDefinition Height="56*"/>

            <RowDefinition Height="44*"/>

            <RowDefinition Height="45*"/>

            <RowDefinition Height="43*"/>

            <RowDefinition Height="50*"/>

            <RowDefinition Height="56*"/>

            <RowDefinition Height="331*"/>


        <TextBlock Text="First array before swapping " Grid.Column="1" Grid.Row="1"  HorizontalAlignment="Left" Foreground="White" FontSize="20" FontWeight="ExtraBold" Width="258"></TextBlock>

        <TextBlock x:Name="text1" Grid.Column="1" Grid.Row="2" Width="200" HorizontalAlignment="Left" Foreground="White" FontSize="20"></TextBlock>

        <TextBlock Text="Second array before swapping " Grid.Column="1" Grid.Row="3"  HorizontalAlignment="Left" Foreground="White" FontSize="20" FontWeight="ExtraBold" Width="285"></TextBlock>

        <TextBlock x:Name="text2" Grid.Column="1" Grid.Row="4" Width="285" HorizontalAlignment="Left" Foreground="White" FontSize="20"></TextBlock>

        <TextBlock Text="First array After swapping " Grid.Column="1" Grid.Row="5"  HorizontalAlignment="Left" Foreground="White" FontSize="20" FontWeight="ExtraBold" Width="258" Visibility="Collapsed" Name="hidetextblock1"></TextBlock>

        <TextBlock x:Name="text3" Grid.Column="1" Grid.Row="6" Width="200" HorizontalAlignment="Left" Foreground="White" FontSize="20"></TextBlock>

        <TextBlock Text="Second array After swapping " Grid.Column="1" Grid.Row="7"  HorizontalAlignment="Left" Foreground="White" FontSize="20" FontWeight="ExtraBold" Width="285" Visibility="Collapsed" Name="hidetextblock2" ></TextBlock>

        <TextBlock x:Name="text4" Grid.Column="1" Grid.Row="8" Width="200" HorizontalAlignment="Left" Foreground="White" FontSize="20"></TextBlock>

        <Button x:Name="button1" Content="Show array After swapping" Background="Yellow" Foreground="Black" Grid.Column="2" Grid.Row="4" Click="button1_Click"></Button>





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 swap_array_app


    public sealed partial class MainPage : Page


        public MainPage()




        protected override void OnNavigatedTo(NavigationEventArgs e)




        int i,j;

        int[] arr1 = { 10, 20, 30, 40, 50 };

        int[] arr2 = { 15, 30, 45, 60, 75 };

        int[] arr3 = new int[5];

        public void showarray()


            for (i = 0; i < arr1.Length; i++)


                text1.Text += arr1[i] + " ";


            for (j = 0; j < arr2.Length; j++)


                text2.Text += arr2[j] + " ";



        private void button1_Click(object sender, RoutedEventArgs e)



            this.hidetextblock1.Visibility = Visibility.Visible;

            this.hidetextblock2.Visibility = Visibility.Visible;


        public void swaparry()


            for (i = 0; i < arr1.Length; i++)


                arr3[i] = arr1[i];

                arr1[i] = arr2[i];

                arr2[i] = arr3[i];


            for (i = 0; i < arr1.Length; i++)


                text3.Text += arr1[i] + " ";


            for (j = 0; j < arr2.Length; j++)


                text4.Text += arr2[j] + " ";






Step 4

Run your app.


After clicking on the button.
