Saving an Email as PDF

This article shows how to convert an email message to PDF using Aspose.Email.  Aspose.Email for .NET deals with network protocols and Microsoft Outlook features, and can not handle direct conversion to PDF. To overcome this, the samples in this article use Aspose.Email to convert the email message to the MHTML stream and then use Aspose.Words for .NET to load the MHTML stream and then save it as PDF.  An email message can contain attachments as well. Since each attachment can be of different media types, Aspose.Email ignores these attachments while converting to MHTML i.e. only inline images in a message will be part of MHTML and any regular attachments will be ignored.

The following code snippet shows you how to convert email messages to PDF.

string dataDir = RunExamples.GetDataDir_KnowledgeBase();
MailMessage mailMsg = MailMessage.Load(dataDir + "message3.msg");
MemoryStream ms = new MemoryStream();
mailMsg.Save(ms, Aspose.Email.SaveOptions.DefaultMhtml);

// create an instance of LoadOptions and set the LoadFormat to Mhtml
var loadOptions = new Aspose.Words.Loading.LoadOptions();
loadOptions.LoadFormat = LoadFormat.Mhtml;

// create an instance of Document and load the MTHML from MemoryStream
var document = new Aspose.Words.Document(ms, loadOptions);

// create an instance of HtmlSaveOptions and set the SaveFormat to Html
var saveOptions = new Aspose.Words.Saving.PdfSaveOptions();
document.Save(dataDir + "SaveEmailAsPDF_out.pdf", saveOptions);
