Copy
// To use the code below, import MailBee namespaces at the top of your code.
using MailBee;
using MailBee.Pop3Mail;

// Put the code below inside your class.

// The actual code.
private void Form1_Load(object sender, System.EventArgs e)
{
    Pop3 pop = new Pop3();

    // Let MailBee process events.
    pop.RaiseEventsViaMessageLoop = false;

    pop.Connect("pop.somehost.com");
    pop.Login("jdoe", "secret");

    // Initiate an asynchronous deletion attempt.
    pop.BeginDeleteMessages(pop.InboxMessageCount - 4, 5, null, null);

    // Simulate some lengthy work here...
    for (int i = 0; i < 100; i++)
    {
        // Make a portion of the work.
        System.Threading.Thread.Sleep(10);

        // Process events which were raised during execution of the work above.
        pop.Wait(0);
    }

    // End the message flagging operation. If it's in progress at the moment 
    // this method starts, it will wait until it's done first.
    pop.EndDeleteMessages();

    // Disconnect from the server.
    pop.Disconnect();
