Parameters

filename
Type: SystemString
The absolute or relative path to the file which should be attached.
targetFilename
Type: SystemString
The filename of the attachment as it should appear in the mail message. If a null reference (Nothing in Visual Basic), MailBee will take it from filename parameter value. If an empty string, the attachment will have no name.
contentID
Type: SystemString
The content identifier (CID) of the attachment (for inline attachments), or empty string if the attachment is not inline.
contentType
Type: SystemString
The content type of the attachment, or a null reference (Nothing in Visual Basic) to let MailBee detect the content type automatically.
customHeaders
Type: MailBee.MimeHeaderCollection
The collection of the headers which should be included into the header section in additon to the standard attachment headers. If a null reference (Nothing in Visual Basic), no custom headers will be added.
options
Type: MailBee.MimeNewAttachmentOptions
The options which affect how the attachment is added.
mailEnc
Type: MailBee.MimeMailTransferEncoding
The mail encoding to use when placing the attachment data into the message.

Return Value

Type: Boolean
true if the attachment was successfully added to the collection; otherwise, false.
Exceptions
ExceptionCondition
MailBeeInvalidArgumentExceptionfilename is a null reference (Nothing in Visual Basic) or an empty string.
MailBeeIOExceptionAn error occurred and ThrowExceptions is true.
Remarks
The targetFilename parameter allows the developer to override the filename under which the attachment will be added to the collection. This is useful when the developer wants to add the attachment from a temporary file such as ETQB4914.TMP under meaningful name such as report.doc.
Note Note
If you're attaching another e-mail message, be sure to use as None as mailEnc value. Some mail services cannot decode attached emails if they are Base64-encoded.
Examples
This sample creates a new message and adds an attachment to this message.

using MailBee;
using MailBee.Mime;

// The actual code (put it into a method of your class)

// Create a new MailMessage object.
MailMessage msg = new MailMessage();

// Add the attachment to the message.
