Find Duplicate Element of an Array in Windows Store App

 Introduction

In this article I explain about an array that contains various duplicate elements and I want to separate each duplicate and non-duplicate element of the array. So I have stored duplicate and non-duplicate elements in separate collections.

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="remove_duplicate_element_of_an_array.MainPage"

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

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

    xmlns:local="using:remove_duplicate_element_of_an_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="110*"/>

            <RowDefinition Height="59*"/>

            <RowDefinition Height="40*"/>

            <RowDefinition Height="45*"/>

            <RowDefinition Height="514*"/>

        </Grid.RowDefinitions>

        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="167*"/>

            <ColumnDefinition Width="248*"/>

            <ColumnDefinition Width="268*"/>

        </Grid.ColumnDefinitions>

        <TextBlock Text="Array content is :" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Column="1"  Grid.Row="1" TextAlignment="Left" Margin="0,0,375,12" Grid.ColumnSpan="2"/>

        <TextBlock x:Name="text1" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Foreground="White" Grid.Row="1" Margin="10,0,-57,0" Grid.Column="2" Width="583" VerticalAlignment="Top" HorizontalAlignment="Left" Height="54" />

        <TextBlock x:Name="text2" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="2" Grid.Row="2" HorizontalAlignment="Left" VerticalAlignment="Top" Height="40" Width="583" Margin="0,0,-47,0"></TextBlock>

        <TextBlock Text="After remove duplicate element array is :" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="1" Grid.Row="2" Foreground="White" HorizontalAlignment="Left" Width="496"  />

        <TextBlock Text="Total duplicat element is : " FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="1" Grid.Row="3"></TextBlock>

        <TextBlock x:Name="text3" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="2" Grid.Row="3" HorizontalAlignment="Left" VerticalAlignment="Top" Height="40" Width="583" Margin="0,0,-47,0"></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;

using System.Collections;

using System.Collections.Generic;

 

namespace remove_duplicate_element_of_an_array

{

    public sealed partial class MainPage : Page

    {

        public MainPage()

        {

            this.InitializeComponent();

        }     

        public void checkduplicate(int[] arr1)

        {

            foreach (int a in arr1)

            {

                text1.Text += a + " ";

            }

            foreach (int a in arr1)

            {

                if (!nondupelement.Contains(a))

                {

                    nondupelement.Add(a);

                    text2.Text += a + " ";

                }

                else if(!dupelement .Contains (a))

                {

                    dupelement.Add(a);

                    text3.Text += a + " ";

                    count++;

                }

            }           

        }

        List<int> dupelement = new List<int>();

        List<int> nondupelement = new List<int>();

        static int count = 0;

 

        protected override void OnNavigatedTo(NavigationEventArgs e)

        {

            int[] arr = { 14, 14, 65, 7, 8, 7, 47, 14, 7, 8 };

          

            checkduplicate(arr);         

        }

    }

}

 

Step 4

Now Run your app.
