Introduction
In this article I explain how to merge two arrays into a single array. To implement this I created two separate arrays with a different size that contains the array elements according to their size and finally another array which with a size equivalent to the first array plus the second array which contains the elements of both the first and second 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="merge_two_array.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:merge_two_array"
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.RowDefinitions>
<RowDefinition Height="81*"/>
<RowDefinition Height="41*"/>
<RowDefinition Height="38*"/>
<RowDefinition Height="37*"/>
<RowDefinition Height="39*"/>
<RowDefinition Height="40*"/>
<RowDefinition Height="492*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="179*"/>
<ColumnDefinition Width="333*"/>
<ColumnDefinition Width="252*"/>
<ColumnDefinition Width="602*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Enter First array Element" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Column="1" Grid.Row="1"></TextBlock>
<TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="1" Width="200" VerticalAlignment="Top" HorizontalAlignment="Left" Height="32" ></TextBox>
<Button x:Name="button1" Grid.Column="2" Grid.Row="2" Background="Yellow" Foreground="Black" Width="150" Content="insert" Height="38" Click="button1_Click"></Button>
<TextBlock Text="Enter First array Element" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Column="1" Grid.Row="3"></TextBlock>
<TextBox x:Name="textbox2" Grid.Column="2" Grid.Row="3" Width="200" VerticalAlignment="Top" HorizontalAlignment="Left" Height="32" ></TextBox>
<Button x:Name="button2" Grid.Column="2" Grid.Row="4" Background="Yellow" Foreground="Black" Width="150" Content="insert" Height="38" Margin="0,1,0,0" Click="button2_Click" RenderTransformOrigin="0.5,0.5">
<Button.RenderTransform>
<CompositeTransform SkewX="6.387" TranslateX="2.127"/>
</Button.RenderTransform>
</Button>
<Button x:Name="button3" Grid.Column="2" Grid.Row="5" Background="Yellow" Foreground="Black" Width="169" Content="Array after Merged" Height="38" Margin="0,2,0,0" Click="button3_Click"></Button>
<TextBlock x:Name="text1" FontFamily="Arial" FontSize="20" FontWeight="ExtraBold" Grid.Column="3" Grid.Row="1" VerticalAlignment="Top" Margin="24,0,0,0" ></TextBlock>
<TextBlock x:Name="text2" FontFamily="Arial" FontSize="20" FontWeight="ExtraBold" Grid.Column="3" Grid.Row="3" VerticalAlignment="Top" Margin="24,0,0,0" ></TextBlock>
<TextBlock x:Name="text3" FontFamily="Arial" FontSize="20" FontWeight="ExtraBold" Grid.Column="3" Grid.Row="5" VerticalAlignment="Top" Margin="24,0,0,0" ></TextBlock>
</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 merge_two_array
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
}
int[] arr1 = new int[5];
int[] arr2 = new int[6];
int i = 0, j=0;
private void button1_Click(object sender, RoutedEventArgs e)
{
if (textbox1 .Text .Length >0)
{
if (i < arr1.Length)
{
arr1[i] = int.Parse(textbox1.Text);
i++;
textbox1.Text = " ";
}
else
{
text1.Text = "Sorry array contain only 5 element";
}
}
}
private void button2_Click(object sender, RoutedEventArgs e)
{
if (textbox2.Text.Length > 0)
{
if (j < arr2.Length)
{
arr2[j] = int.Parse(textbox2.Text);
j++;
textbox2.Text = " ";
}
else
{
text2.Text = "Sorry array contain only 6 element";
}
}
}
private void button3_Click(object sender, RoutedEventArgs e)
{
int[] arr3 = new int[arr1.Length + arr2.Length];
Array.Copy(arr1,0, arr3, 0,arr1.Length);
Array.Copy(arr2,0, arr3,arr1.Length,arr2 .Length);
foreach (int a in arr3)
{
text3.Text += a + " ";
}
}
}
}
Step 4
Now Run your app.
