DnsEventHandler Delegate

Represents the method (event handler) that is raised when the Dns.BeginGetHost or Dns.BeginGetMailHosts method completes.

[Visual Basic]
Public Delegate Sub DnsEventHandler( _
   ByVal sender As Object, _
   ByVal e As DnsEventArgs _
) 

[C#]
public delegate void DnsEventHandler( 
   object sender,
   DnsEventArgs e
);

[C++]
public: __gc __delegate void DnsEventHandler( 
   Object* sender,
   DnsEventArgs* e
)

[C++/CLI]
public delegate void DnsEventHandler( 
   Object^ sender,
   DnsEventArgs^ e
)

Parameters

sender

The source of the event.

e

A DnsEventArgs object that contains the event data.

Remarks

As Microsoft describes in their MSDN documentation, the event model in the .NET Framework is based on having an event delegate that connects an event with its handler. To raise an event, two elements are needed:

• A class that holds the event data. This class must derive from the base class EventArgs.
• A delegate that points to a method that provides the response to the event.

For more information about event handler delegates, see the Using Events In PowerTCP topic.
