Aspose.Email for .NET 25.2 Release Notes

All Changes

New Features

1. Support for Filtering or Searching Messages in MBOX Files

Aspose.Email for .NET now provides the ability to filter or search messages within MBOX files using a query. This enhancement allows developers to efficiently retrieve only the messages that match specific criteria, improving performance and usability when working with large MBOX files.

API Changes:

• Added EnumerateMessages(MailQuery query), which returns an enumerable collection of MailMessage instances that match the specified query.
• Added EnumerateMessageInfo(MailQuery query), which returns an enumerable collection of MboxMessageInfo instances that match the specified query.

Code Example:

using Aspose.Email.Storage.Mbox;
using Aspose.Email;

var reader = MboxStorageReader.CreateReader("input.mbox", new MboxLoadOptions());
var mqb = new MailQueryBuilder();
mqb.Subject.Contains("Project Update");
mqb.SentDate.Before(DateTime.Today);

foreach (var message in reader.EnumerateMessages(mqb.GetQuery()))
{
    Console.WriteLine("Subject: " + message.Subject);
}

2. Support for Paginated Retrieval of Messages from MBOX Files

Aspose.Email for .NET now supports paginated retrieval of messages from MBOX files. This feature allows for efficient processing of large MBOX files by retrieving messages in smaller batches, reducing memory consumption and improving performance.

API Changes:

• Added EnumerateMessages(int startIndex, int count), which retrieves a specified number of MailMessage instances starting from a given index.
• Added EnumerateMessageInfo(int startIndex, int count), which retrieves a specified number of MboxMessageInfo instances starting from a given index.

Code Example:

using Aspose.Email.Storage.Mbox;
using Aspose.Email;

var reader = MboxStorageReader.CreateReader("input.mbox", new MboxLoadOptions());
int startIndex = 0;
int count = 10; // Retrieve messages in batches of 10

foreach (var message in reader.EnumerateMessages(startIndex, count))
{
    Console.WriteLine("Subject: " + message.Subject);
}
