Find Largest Element of an Array in Windows Store App


We all know that an array is a collection of homogenous data types. In other words, one array can contain several elements depending on their defined size or you can assign a value at the time of declaration. Since an array is a collection of several elements of the same data type we can perform various types of operations on the array, like search for the largest, smallest, second highest or second smallest element within an array.

Here in this article I will find the largest element from an 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):










    <Grid Background="Red">


            <RowDefinition Height="110*"/>

            <RowDefinition Height="59*"/>

            <RowDefinition Height="40*"/>

            <RowDefinition Height="559*"/>



            <ColumnDefinition Width="167*"/>

            <ColumnDefinition Width="156*"/>

            <ColumnDefinition Width="360*"/>


        <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="10,10,0,0" Grid.Column="2" Width="401" VerticalAlignment="Top" HorizontalAlignment="Left" Height="23" />

        <TextBlock x:Name="text2" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="2" Grid.Row="2" HorizontalAlignment="Left" VerticalAlignment="Top" Height="23" Width="53"></TextBlock>

        <TextBlock Text="Largest Number in array is :" FontSize="20" FontFamily="Arial" FontWeight="ExtraBold" Grid.Column="1" Grid.Row="2" Foreground="White" HorizontalAlignment="Left" Grid.RowSpan="2" Width="306"  />




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 find_largest_no_in_array


    public sealed partial class MainPage : Page


        public MainPage()




        protected override void OnNavigatedTo(NavigationEventArgs e)


            int[] arr = { 10, 12, 5, 2, 9, 58, 4, 88, 6 };

            for (int i = 0; i < arr.Length; i++)


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


            int big = arr[0];

            for (int j = 1; j < arr.Length; j++)


                if (big < arr[j])


                    big = arr[j];



            text2.Text = big.ToString();





Step 4

Now Run Your app.
