C# and XAML App to Show Computer Name Domain and IP

I recently put together a little application written in C# and XAML (eXtensible Application Markup Language) which provides a user with their computer name, domain and IP addresses.

At work we have an older tool which does something similar but I wanted to get to grips with C’# and this seemed like a good place to start. Now I want you to understand I am in no way a developer so I wouldn’t be surprised if I have mistakes or areas I could improve on. If you are a developer or have useful feedback I welcome it. I’m lucky enough to have an MSDN subscription through work so I used Visual Studio 2015 Enterprise edition to create this project.

Going forward I’d like to enhance this application with some extra features –

  • Indicator circle which sets its colour –
    • Green – connected to the users primary Active Directory network and able to ping the domain name
    • Amber – connected to a network and able to ping an Internet resource
    • Red – no network connectivity
  • Additional network information, e.g which adapters IP addresses are bound to
  • Additional tabs
    • Currently logged on user details
    • System information such as free drive space

I’m sure other ideas will pop into my mind but for the moment I have the above to work on.

Here is an example screenshot of the application –

Clicking the copy button will add the field values to the clipboard, if you then paste those values into say Notepad you will get something similar to this –

Copy Output Example



<Window x:Name="Computer_Name" x:Class="ComputerName.MainWindow"
         Title="Computer Name" Height="248.345" Width="290.483" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" WindowStyle="ToolWindow">
             <ColumnDefinition Width="Auto"/>
         <TextBlock x:Name="ComputerName" HorizontalAlignment="Left" Margin="10,21,0,0" TextWrapping="Wrap" Text="Computer Name" VerticalAlignment="Top"/>
         <TextBox x:Name="MachineName" HorizontalAlignment="Left" Height="23" Margin="127,21,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120" Initialized="MachineName_Initialized" IsReadOnly="True"/>
         <TextBlock x:Name="DomainName" HorizontalAlignment="Left" Margin="10,71,0,0" TextWrapping="NoWrap" Text="Domain Name" VerticalAlignment="Top"/>
         <TextBox x:Name="Domain" HorizontalAlignment="Left" Height="23" Margin="127,71,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120" Initialized="Domain_Initialized" IsReadOnly="True"/>
         <TextBlock x:Name="IPAddresses" HorizontalAlignment="Left" Margin="10,120,0,0" TextWrapping="Wrap" Text="IP Addresses" VerticalAlignment="Top"/>
         <ListBox x:Name="IPs" HorizontalAlignment="Left" Height="84" Margin="127,120,0,0" VerticalAlignment="Top" Width="120" Initialized="IPs_Initialized"/>
         <Button x:Name="Copy" Content="Copy" HorizontalAlignment="Left" Margin="10,180,0,0" VerticalAlignment="Top" Width="74" ToolTip="Click to copy details" Click="Copy_Click" RenderTransformOrigin="0.5,1.5"/>




C# Code

using System.Windows;
using System.Net;
using System.Linq;

namespace ComputerName

    public partial class MainWindow : Window
         IPAddress[] addresses;
         public MainWindow()


        private void MachineName_Initialized(object sender, System.EventArgs e)
             MachineName.Text = (System.Environment.MachineName);

        private void Domain_Initialized(object sender, System.EventArgs e)
             Domain.Text = (System.Environment.UserDomainName);

        private void IPs_Initialized(object sender, System.EventArgs e)
             addresses = Dns.GetHostAddresses(Dns.GetHostName()).Where(a => a.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork).ToArray();

            foreach (object address in addresses)


        private void Copy_Click(object sender, RoutedEventArgs e)
             string copiedDetails = MachineName.Text + "\r\n" + Domain.Text + "\r\n";

            foreach (var ipAddress in addresses)
                 copiedDetails += ipAddress.ToString() + "\r\n";





I’m quite happy with this little app, there is certainly lots I can do to enhance and improve it. While learning to be a C# developer isn’t exactly my goal it is nice to be able to put something together and learn some new skills.
