Display Number From 1 to 100 Without Loop in Windows Store App


Today I am describing a very simple but interesting thing. Because we always print number from 1 to 100 using a loop. But someone asked me how to print these numbers without using a loop. Really at that time I had no idea although I proceeded to do it. I finally got the idea to use recursion (in which a method calls itself) and print the number.

Use the following procedure to implement it.

Step 1

First of all you have to create a new Windows Store Application, as in:

  • 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="116*"/>

            <RowDefinition Height="45*"/>

            <RowDefinition Height="518*"/>

            <RowDefinition Height="89*"/>



            <ColumnDefinition Width="215*"/>

            <ColumnDefinition Width="479*"/>           

            <ColumnDefinition Width="200*"/>


        <TextBlock Text="Display Number from 1 to 100 without loop" FontSize="20" FontWeight="ExtraBold" FontFamily="Arial" Grid.Column="1" Grid.Row="1" Grid.ColumnSpan="2"></TextBlock>

        <TextBlock x:Name="text1"  FontSize="20" FontWeight="ExtraBold" FontFamily="Arial" Grid.Column="1" Grid.Row="2" HorizontalAlignment="Left" Width="722" TextWrapping="Wrap" Margin="0,0,0,40"></TextBlock>       




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 number_app


    public sealed partial class MainPage : Page


        public MainPage()




        protected override void OnNavigatedTo(NavigationEventArgs e)




        public void number(int num)


            if(num <=100)


            text1.Text += num.ToString() + " ";

            number(num + 1);






Step 4

Run your app and see the output.
