Imap.HostResolved Event

Occurs when the IMAP4 server name is successfully resolved into IP address(es).

public event HostResolvedEventHandler HostResolved;

Event Data

The event handler receives an argument of type HostResolvedEventArgs containing data related to this event. The following HostResolvedEventArgs properties provide information specific to this event.

Property Description
RemoteHost Gets a reference to the resolved host data.
State Gets a reference to the object which was supplied by the developer in state parameter of asynchronous methods of the mailer components.

Remarks

If the IMAP4 server name (serverName parameter of Connect method) was already specified as an IP address, this event is still raised.

Note   No checking if performed on whether the resolved IP address points to the live host.

Example

This sample connects to the IMAP4 server host and prints all the IP addresses of this host into console. Most hosts, however, have only one IP address assigned.

[C#]
using System;
using MailBee;
using MailBee.ImapMail;

class Sample
{
    // HostResolved event handler.
    private static void OnHostResolved(object sender, HostResolvedEventArgs e)
    {
        foreach (System.Net.IPAddress ip in e.RemoteHost.AddressList)
        {
            Console.WriteLine(ip.ToString());
        }
    }

    // The actual code.
    static void Main(string[] args)
    {
        Imap imp = new Imap();

        // Subscribe to the HostResolved event.
        imp.HostResolved += new HostResolvedEventHandler(OnHostResolved);

        imp.Connect("imap.company.com");
        imp.Disconnect();
    }
}
