Chilkat for .NET Core

Chilkat for Mono

// Every part in a MIME messsage should include a Content-Type header field.
// The Content-Type indicates the type of content contained in the MIME part.
// For example: text/plain, image/jpeg, application/pdf, application/json, multipart/mixed, etc.

// Multipart content types are those where the MIME part's body is composed of N inner MIME messages,
// separated by a boundary string.
// This is how MIME gets a nested, tree-like structure.  The most common multipart MIME types
// are (for email related MIME) multipart/mixed, multipart/alternative, and multipart/related,
// and for HTTP related MIME, it is multipart/form-data.

bool success;
Chilkat.Mime mime = new Chilkat.Mime();

// The Content-Type header field can be set or modified in two ways.
// 1) By setting the ContentType, Micalg, Name, Charset, Boundary, or Protocol properties.
//    Setting the ContentType property sets the primary value (such as "text/plain") of the header field.
//    Each of the other properties listed above will replace or add a particular attribute value.

// 2) By setting the entire contents of the ContentType header with the SetHeaderField method.
//    This updates each of the Content-Type related properties.

// For example:
mime.ContentType = "text/plain";
mime.Charset = "utf-8";

// The Content-Type header field contains this:
//     Content-Type: text/plain; charset=utf-8
Debug.WriteLine(mime.GetEntireHead());
Debug.WriteLine("-");

mime.SetHeaderField("Content-Type","image/jpeg; name=\"kitty.jpg\"");
// The Content-Type header field now contains this:
//     Content-Type: image/jpeg; name="kitty.jpg"
Debug.WriteLine(mime.GetEntireHead());
Debug.WriteLine("-");

// Notice how the properties have been updated:
Debug.WriteLine("ContentType property: " + mime.ContentType);
Debug.WriteLine("Charset property: " + mime.Charset);
Debug.WriteLine("Name property: " + mime.Name);
Debug.WriteLine("-");

// To change a particular attribute value, set the property.
mime.Name = "doggy.jpg";
Debug.WriteLine(mime.GetEntireHead());
Debug.WriteLine("-");

// To remove an attribute value from the Content-Type header,
// set the property to an empty string.
mime.Name = "";
Debug.WriteLine(mime.GetEntireHead());
Debug.WriteLine("-");
