Query DNS servers for MX and all the other resource record types defined by RFC-1034 and RFC-1035. The DNS .NET class library makes it easy to retrieve the list of configured DNS servers, construct a DNS query request using the convenient message and resource record classes, send the request to a DNS server and receive the fully parsed response. Written in 100% managed C# code, the class library offers .NET developers complete access to DNS resources from within their applications.
