Introduction
In my previous article I described how to Delete specific element of an array and in this article I explain how to insert an element at a specific position and also do not increate the size of 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="delete_specific_element_from_array.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:delete_specific_element_from_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="72*"/>
<RowDefinition Height="38*"/>
<RowDefinition Height="42*"/>
<RowDefinition Height="35*"/>
<RowDefinition Height="40*"/>
<RowDefinition Height="79*"/>
<RowDefinition Height="36*"/>
<RowDefinition Height="33*"/>
<RowDefinition Height="40*"/>
<RowDefinition Height="42*"/>
<RowDefinition Height="311*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="248*"/>
<ColumnDefinition Width="407*"/>
<ColumnDefinition Width="257*"/>
<ColumnDefinition Width="454*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Enter Element of an array" FontFamily="Arial" Grid.Column="1" Grid.Row="2" Foreground="White" FontSize="20" FontWeight="ExtraBold" ></TextBlock>
<TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="2" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32"></TextBox>
<Button x:Name="button1" Content="Insert" Grid.Column="2" Grid.Row="3" Background="Yellow" Foreground="Black" Width="97" Height="35" Click="button1_Click" ></Button>
<TextBlock x:Name="text1" FontFamily="Arial" Grid.Column="3" Grid.Row="2" FontSize="20" FontWeight="ExtraBold" ></TextBlock>
<Button x:Name="button2" Content="show array element" Background="Yellow" Foreground="Black" Grid.Column="2" Grid.Row="4" Height="40" Width="171" Click="button2_Click"/>
<TextBlock x:Name="text2" FontFamily="Arial" Grid.Column="1" Grid.Row="5" FontSize="20" FontWeight="ExtraBold" ></TextBlock>
<TextBlock Text="Enter the position for insert Number" FontFamily="Arial" Grid.Column="1" Grid.Row="6" FontSize="20" FontWeight="ExtraBold" Grid.RowSpan="2" ></TextBlock>
<TextBox x:Name="textbox2" Grid.Column="2" Grid.Row="6" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32"></TextBox>
<Button x:Name="button3" Content="Inset at position" Grid.Column="2" Grid.Row="8" Background="Yellow" Foreground="Black" Width="200" Height="35" Margin="0,5,0,0" Click="button3_Click" />
<Button x:Name="button4" Content=" Show after Delete array element" Grid.Column="2" Grid.Row="8" Background="Yellow" Foreground="Black" Width="257" Height="35" Margin="0,38,0,9" Click="button4_Click" Grid.RowSpan="2" />
<TextBlock Text="Enter Element to insert" FontFamily="Arial" Grid.Column="1" Grid.Row="7" FontSize="20" FontWeight="ExtraBold" Grid.RowSpan="2" ></TextBlock>
<TextBlock x:Name="text3" FontFamily="Arial" Grid.Column="1" Grid.Row="10" FontSize="20" FontWeight="ExtraBold" ></TextBlock>
<TextBox x:Name="textbox3" Grid.Column="2" Grid.Row="7" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32" />
</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 delete_specific_element_from_array
{
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 (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)
{
for (int i = 0; i < arr.Length; i++)
{
text2.Text += arr[i] + " ";
}
}
private void button3_Click(object sender, RoutedEventArgs e)
{
int pos = int.Parse(textbox2.Text);
if (pos <= arr.Length)
{
int value = int.Parse(textbox3.Text);
arr[pos] = value;
}
}
private void button4_Click(object sender, RoutedEventArgs e)
{
foreach (int a in arr)
{
text3.Text += a + " ";
}
}
}
}
Step 4
Now Run your app.
