What's New in ComponentSpace DNS?

ComponentSpace DNS is now 64 bit, .NET framework 4 and VS 2010 compatible.


ComponentSpace DNS Component may be used in any Windows or Web application by adding a reference to the assembly to access the classes in the KeyTech.Dns namespace. ComponentSpace DNS is now 64bit, .NET framework 4 and VS2010 compatible.

The DnsMessage class models DNS request and response messages. It makes it very easy to construct DNS requests and access DNS responses. A separate class describes each resource record type. Each resource record class is derived from the ResourceRecord abstract class.

The list of resource record classes includes:

  • ARecord,
  • CNAMERecord,
  • HINFORecord,
  • MBRecord,
  • MDRecord,
  • MFRecord,
  • MGRecord,
  • MINFORecord,
  • MRRecord,
  • MXRecord,
  • NSRecord,
  • NULLRecord,
  • PTRRecord,
  • SOARecord,
  • TXTRecord,
  • WKSRecord
  • A catch all OtherRecord.

The DnsClient class allows you to send DnsMessage requests and receive DnsMessage responses. Within the DnsMessage request you specify the DNS questions to ask. The DnsMessage response contains the lists of ResourceRecords.

You may send requests from within DnsClient either synchronously (blocking) using the Send method or asynchronously (non-blocking) using the BeginSend and EndSend methods. Similarly, responses may be received either synchronously (blocking) using the Receive method or asynchronously (non-blocking) using the BeginReceive and EndReceive methods. For asynchronous calls you may receive completion notification either through an event or a callback method. A timeout may be specified.

All classes that raise events support a SynchronizingObject property. All classes report errors through the DnsException.
