Keterangan

Metode menambahkan AddObject<Object> elemen yang mewakili objek yang akan ditandatangani ke <Signature> elemen tanda tangan digital XML.

Metode ini AddObject secara internal memanggil AddObject metode objek yang Signature dienkapsulasi oleh SignedXml objek . Anda juga dapat menambahkan DataObject objek dengan langsung memanggil AddObject metode dari Signature properti .

Untuk informasi selengkapnya tentang tanda tangan digital XML, lihat spesifikasi XMLDSIG.
