How to get the client machine name? I tried different codes, but am getting the Server Domain Name. Is there any code to get correct client machine name.

What I have tried:

public static string GetComputerName()
{
try
{
string[] computer_name = System.Net.Dns.GetHostEntry(HttpContext.Current.Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
String ecname = System.Environment.MachineName;
return computer_name[0].ToString();
}
catch (Exception ex)
{
return string.Empty;
}
}
