Gets or sets the DNS name of the host.

Namespace:  System.Net
Assembly:  System (in System.dll)

public string HostName { get; set; }

Property Value

Type: System.String
A string that contains the primary host name for the server.

The HostName property contains the primary host name for a server. If the DNS entry for the server defines additional aliases, they will be available in the Aliases property.

The following example uses the HostName property to retrieve the primary host name.


   public void GetIpAddressList(String hostString)
   {
	   try 
	   {
		   // Get 'IPHostEntry' object containing information like host name, IP addresses, aliases for a host.
		   IPHostEntry hostInfo = Dns.GetHostByName(hostString);
		   Console.WriteLine("Host name : " + hostInfo.HostName);
		   Console.WriteLine("IP address List : ");
		   for(int index=0; index < hostInfo.AddressList.Length; index++)
		   {
			   Console.WriteLine(hostInfo.AddressList[index]);
		   }
	   }
	   catch(SocketException e) 
	   {
		   Console.WriteLine("SocketException caught!!!");
		   Console.WriteLine("Source : " + e.Source);
		   Console.WriteLine("Message : " + e.Message);
	   }
	   catch(ArgumentNullException e)
	   {
		   Console.WriteLine("ArgumentNullException caught!!!");
		   Console.WriteLine("Source : " + e.Source);
		   Console.WriteLine("Message : " + e.Message);
	   }
	   catch(Exception e)
	   {
		   Console.WriteLine("Exception caught!!!");
		   Console.WriteLine("Source : " + e.Source);
		   Console.WriteLine("Message : " + e.Message);
	   }
   }
