[get: System.Runtime.TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")]
[set: System.Runtime.TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")]
public System.Net.IPAddress[] AddressList { get; set; }
member this.AddressList : System.Net.IPAddress[] with get, set
Public Property AddressList As IPAddress()
Property Value

An array of type IPAddress that contains IP addresses that resolve to the host names that are contained in the Aliases property.

Examples

The following example uses the AddressList property to access the IP addresses that are associated with the IPHostEntry.

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 : {0}", 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 : {0}", e->Source );
      Console::WriteLine( "Message : {0}", e->Message );
   }
   catch ( ArgumentNullException^ e ) 
   {
      Console::WriteLine( "ArgumentNullException caught!!!" );
      Console::WriteLine( "Source : {0}", e->Source );
      Console::WriteLine( "Message : {0}", e->Message );
   }
   catch ( Exception^ e )

      Console::WriteLine( "Exception caught!!!" );
      Console::WriteLine( "Source : {0}", e->Source );
      Console::WriteLine( "Message : {0}", e->Message );
   }
}
