Swap the Value of Two Arrays in Windows Store App

Introduction

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):

<Page

    x:Class="swap_array_app.MainPage"

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

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

    xmlns:local="using:swap_array_app"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d">

 

    <Grid Background="Red">

        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="275*"/>

            <ColumnDefinition Width="321*"/>

            <ColumnDefinition Width="770*"/>

        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>

            <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*"/>

        </Grid.RowDefinitions>

        <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>

 

    </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 swap_array_app

{

    public sealed partial class MainPage : Page

    {

        public MainPage()

        {

            this.InitializeComponent();

        }

        protected override void OnNavigatedTo(NavigationEventArgs e)

        {

            showarray();

        }

        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)

        {

            swaparry();

            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.
