Keterangan

Jika Anda menentukan Name nilai properti saat menerapkan atribut, semua XmlElement atau XmlNode objek yang dimasukkan ke dalam array harus memiliki nama elemen dan namespace default yang sama, atau pengecualian dilemparkan. Jika Anda mengatur Namespace nilai properti, Anda juga harus mengatur Name properti , dan XmlElement objek atau XmlNode juga harus memiliki nama dan nilai namespace yang sama. Jika tidak ada Name nilai yang ditentukan, XmlElement objek atau XmlNode dapat memiliki nama elemen apa pun.

Saat Anda memanggil Deserialize metode XmlSerializer kelas, semua atribut yang tidak memiliki anggota yang sesuai dalam objek yang dideserialisasi dikumpulkan dalam array. Jika Anda menentukan Name nilai, array hanya berisi elemen XML dengan nama tersebut. Jika Anda tidak menentukan Name nilai, array berisi semua elemen yang tidak memiliki anggota yang sesuai di kelas . Jika kelas berisi lebih dari satu bidang yang atributnya diterapkan, gunakan Name properti dan Namespace untuk membedakan antara konten array. Jika kelas seperti itu (dengan beberapa bidang) juga berisi satu bidang yang tidak memiliki kumpulan nilai properti pembeda (yaitu, Name dan Namespace) selama deserialisasi, array berisi elemen XML apa pun yang belum terkandung dalam array lain. Jika Anda menambahkan lebih dari satu bidang yang tidak memiliki set pembeda Name atau Namespace nilai, bidang terakhir di kelas berisi semua elemen tidak dikenal yang belum terkandung dalam array lain, dan bidang lain diatur ke null.

Anda dapat menerapkan beberapa instans XmlAnyElementAttribute ke anggota kelas, tetapi setiap instans harus memiliki nilai properti yang berbeda Name . Atau, jika properti yang sama Name diatur untuk setiap instans, nilai properti yang berbeda Namespace harus diatur untuk setiap instans.
