New Features

Set the X-ALT-DESC header in ICS file

The X-ALT-DESC header is a HTML formatted description in iCalendar (.ics) items. To create an appointment with HTML content, set the IsDescriptionHtml property to true.

Code sample

var appointment = new Appointment("Bygget 83",
    DateTime.UtcNow, // start date
    DateTime.UtcNow.AddHours(1), // end date
    new MailAddress("", "Tintin Strom"), // organizer
    new MailAddress("", "Aina Martensson")) // attendee
    IsDescriptionHtml = true,

    Description = @"
       <style type=""text/css"">
        .text {
               font-family:'Comic Sans MS';
       <p class=""text"">Hi, I'm happy to invite you to our party.</p>

List the message attachments using the IMAP client

A feature has been added to get information about attachments such as name, size without fetching the attachment data.

Changes in public API

Aspose.Email.Clients.Imap.ImapAttachmentInfo - Represents an attachment information. Aspose.Email.Clients.Imap.ImapAttachmentInfoCollection - Represents a collection of ImapAttachmentInfo. Aspose.Email.Clients.Imap.ListAttachments(int sequenceNumber) - Gets an information for each attachment in message.

Code sample

var messageInfoCollection = imapClient.ListMessages();
foreach (var message in messageInfoCollection)
    var attachmentInfoCollection = imapClient.ListAttachments(message.SequenceNumber);

    foreach (var attachmentInfo in attachmentInfoCollection)
        Console.WriteLine("Attachment: {0} (size: {1})", attachmentInfo.Name, attachmentInfo.Size);

Fetching items with attachments via EwsClient

We added the FetchItems(EwsFetchItems options) method to EwsClient. It accepts an instance of EwsFetchItems class as a parameter to control the behavior of the method.

For example, the following code shows how to get items with attachments.

Code sample

var messageInfoList = ewsClient.ListMessages(ewsClient.MailboxInfo.InboxUri);
var options = EwsFetchItems.Create();
var uriList = messageInfoList.Select(item => item.UniqueUri).ToList();
var items = ewsClient.FetchItems(options.AddUris(uriList).WithAttachments());
