Working with Random numbers in Windows Phone

Working with Random Numbers in Windows Phone

random number in c#

 

For developing a game like application or developing a Quiz application, many people try to generate a Random number with their own algorithm.

But Windows Phone has a very useful way to generate the Random number in minutes. Even you can specify boundary for the Random number to be generated (E.g number should between 0 to 10).

here is the simple way to generate the Random number

Random myRandom=new Random();
int randomNumber=myRandom.Next(0,100);

so  we have to create an object for Random class first and then we have to specify the boundary by Next method.

myRandom.Next(0,100) which generates the number between 0 to 99 (but not 100) and we have to store it in a integer variable

I created a sample application which generate random number every time a button event is clicked.

Project Name: RandomNumberSample

MainPage.xaml

<phone:PhoneApplicationPage
    x:Class="RandomNumberSample.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;      assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True">

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
   <TextBlock Height="93" HorizontalAlignment="Left" Margin="69,81,0,0" Name="textBlock1" Text="Random Number" VerticalAlignment="Top" FontSize="48" />
   <TextBlock Height="80" HorizontalAlignment="Left" Margin="141,265,0,0" Name="textBlock2" Text="" VerticalAlignment="Top" FontSize="56" />
        <Button Content="Generate !!!" Height="72" HorizontalAlignment="Left" Margin="141,437,0,0" Name="button1" VerticalAlignment="Top" Width="214" Click="button1_Click" />
        <TextBlock Height="30" HorizontalAlignment="Left" Margin="176,158,0,0" Name="textBlock3" Text="between 1 to 100" VerticalAlignment="Top" />

    </Grid>   

</phone:PhoneApplicationPage> 

MainPage.xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace RandomNumberSample
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            Random myRandom = new Random();
            int randomNumber = myRandom.Next(0, 100);
            textBlock2.Text = Convert.ToString(randomNumber);
        }
    }
}
So when you execute this application you will get the output like below

  3. I don't think why developers are working with random numbers they can develop their own code to
    develop their application.
