Serialize MIME to a StringBuilder

Demonstrates the Chilkat Mime.GetMimeSb method, which serializes the complete MIME entity and appends it to a StringBuilder. The only argument is the StringBuilder; existing content is preserved.

Background: Serializing into a StringBuilder avoids creating a new string and is convenient when you are accumulating output or building a larger document. Because it appends, you can assemble several pieces in one buffer. As with GetMime, use the BinData form for content with arbitrary binary bytes.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

//  Demonstrates the Mime.GetMimeSb method, which serializes the complete MIME entity and appends
//  it to a StringBuilder.  The only argument is the StringBuilder.

var mime = new CkMime();

success = mime.SetBodyFromPlainText("Hello, this is the message body.");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

//  Append the serialized MIME to a StringBuilder.  Existing content is preserved.
var sb = new CkStringBuilder();
success = mime.GetMimeSb(sb);
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log(sb.GetAsString());
