• System.Environment.MachineName from a console or WinForms app.
• HttpContext.Current.Server.MachineName from a web app
• System.Net.Dns.GetHostName() to get the FQDN

See How to find FQDN of local machine in C#/.NET ? if the last doesn't give you the FQDN and you need it.

See details about Difference between SystemInformation.ComputerName, Environment.MachineName, and Net.Dns.GetHostName

---

System.Environment.MachineName

Or, if you are using Winforms, you can use System.Windows.Forms.SystemInformation.ComputerName, which returns exactly the same value as System.Environment.MachineName.

System.Environment.MachineName

Well there is one more way: Windows Management Instrumentation

using System.Management;

try
        {
            ManagementObjectSearcher searcher =
                new ManagementObjectSearcher("root\\CIMV2",
                "SELECT Name FROM Win32_ComputerSystem");

            foreach (ManagementObject queryObj in searcher.Get())
            {
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Win32_ComputerSystem instance");
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Name: {0}", queryObj["Name"]);
            }
        }
        catch (ManagementException e)
        {
            // exception handling
        }

Try this:

string[] computer_name = System.Net.Dns.GetHostEntry(System.Web.HttpContext.Current.Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
return computer_name[0].ToString();

I set the .InnerHtml of a <p> bracket for my web project to the user's computer name doing the following:

HTML:

    <div class="col-md-4">
       <h2>Your Computer Name Is</h2>
       <p id="pcname" runat="server"></p>
       <p>
           <a class="btn btn-default" href="#">Learn more &raquo;</a>
       </p>
    </div>

C#:

using System;
using System.Web.UI;

namespace GetPCName {
   public partial class _Default : Page {
    protected void Page_Load(object sender, EventArgs e) {            
        pcname.InnerHtml = Environment.MachineName;
    }
   }
}

2 more helpful methods: System.Environment.GetEnvironmentVariable("ComputerName" )

System.Environment.GetEnvironmentVariable("ClientName" ) to get the name of the user's PC if they're connected via Citrix XenApp or Terminal Services (aka RDS, RDP, Remote Desktop)

---

Try this one.

public static string GetFQDN()
{
    string domainName = NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
    string hostName = Dns.GetHostName();
    string fqdn;
    if (!hostName.Contains(domainName))
        fqdn = hostName + "." +domainName;
    else
        fqdn = hostName;

    return fqdn;
}

Make it simple by using this one line

Environment.MachineName;
