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

Code Example:

auto reader = MboxStorageReader::CreateReader(u"input.mbox", MakeObject<MboxLoadOptions>());
auto mqb = MakeObject<MailQueryBuilder>();
mqb->get_Subject()->Contains(u"Project Update");
mqb->get_SentDate()->Before(System::DateTime::get_Today());

for (auto&& message : reader->EnumerateMessages(mqb->GetQuery()))
{
    std::wcout << u"Subject: " << message->get_Subject() << std::endl;
}

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:

int startIndex = 0;
int count = 10; // Retrieve messages in batches of 10

for (auto&& message : reader->EnumerateMessages(startIndex, count))
{
    std::wcout << u"Subject: " << message->get_Subject() << std::endl;
}
