Public Methods

Method	Description
Accept ( MimeKit.MimeVisitor visitor ) : void	Dispatches to the specific visit method for this MIME entity. This default implementation for MimeKit.MimePart nodes calls MimeKit.MimeVisitor.VisitMimePart. Override this method to call into a more specific method on a derived visitor class of the MimeKit.MimeVisitor class. However, it should still support unknown visitors by calling MimeKit.MimeVisitor.VisitMimePart.
ComputeContentMd5 ( ) : string	Computes the MD5 checksum of the content. Computes the MD5 checksum of the MIME content in its canonical format and then base64-encodes the result.
GetBestEncoding ( EncodingConstraint constraint, CancellationToken cancellationToken = default(CancellationToken) ) : ContentEncoding	Calculates the most efficient content encoding given the specified constraint. If no ContentObject is set, ContentEncoding.SevenBit will be returned.
GetBestEncoding ( EncodingConstraint constraint, int maxLineLength, CancellationToken cancellationToken = default(CancellationToken) ) : ContentEncoding	Calculates the most efficient content encoding given the specified constraint. If no ContentObject is set, ContentEncoding.SevenBit will be returned.
MimePart ( ) : System	Initializes a new instance of the MimeKit.MimePart class with the default Content-Type of application/octet-stream. Creates a new MimePart with a Content-Type of application/octet-stream.
MimePart ( MimeKit.ContentType contentType ) : System	Initializes a new instance of the MimeKit.MimePart class with the specified content type. Creates a new MimePart with the specified Content-Type value.
MimePart ( MimeKit.MimeEntityConstructorArgs args ) : System	Initializes a new instance of the MimeKit.MimePart class based on the MimeEntityConstructorArgs. This constructor is used by MimeKit.MimeParser.
MimePart ( string contentType ) : System	Initializes a new instance of the MimeKit.MimePart class with the specified content type. Creates a new MimePart with the specified Content-Type value.
MimePart ( string mediaType, string mediaSubtype ) : System	Initializes a new instance of the MimeKit.MimePart class with the specified media type and subtype. Creates a new MimePart with the specified media type and subtype.
Prepare ( EncodingConstraint constraint, int maxLineLength = 78 ) : void	Prepare the MIME entity for transport using the specified encoding constraints. Prepares the MIME entity for transport using the specified encoding constraints.
VerifyContentMd5 ( ) : bool	Verifies the Content-Md5 value against an independently computed md5sum. Computes the MD5 checksum of the MIME content and compares it with the value in the Content-MD5 header, returning `true` if and only if the values match.
WriteTo ( MimeKit.FormatOptions options, Stream stream, bool contentOnly, CancellationToken cancellationToken = default(CancellationToken) ) : void	Writes the MimeKit.MimePart to the specified output stream. Writes the MIME part to the output stream.

Protected Methods

Method	Description
OnHeadersChanged ( HeaderListChangedAction action, Header header ) : void	Called when the headers change in some way. Updates the ContentTransferEncoding, ContentDuration, and ContentMd5 properties if the corresponding headers have changed.
