Send a Word file as an Email body in C# and VB.NET
If you need to compose emails using more advanced features programmatically, you can use Word documents in the email body with your C# and VB.NET applications.
With GemBox.Email you can write emails in EML, MHT, and MSG formats. With the GemBox.Document component you can read documents from formats such as DOC and DOCX.
By combining these components, you can create emails from Word files by using the MHTML format as an intermediate. In other words, you can load a Word file into a DocumentModel object, save it as HtmlType.Mhtml, and then load it as a MailMessageFormat.Mhtml email into MailMessage.
The example below shows how you can send a Word document as an email message from a C# or VB.NET application by converting the DOC or DOCX file into an email body and adding additional content (such as subject, date, sender, and receiver). The generated email retains images, styles, and formatting from the Word template.
