Keterangan

Tabel berikut mencantumkan tipe data sederhana Skema XML dengan their.NET setara.

Untuk Skema base64Binary XML dan hexBinary jenis data, gunakan array Byte struktur, dan terapkan SoapAttributeAttribute dengan DataType yang diatur ke "base64Binary" atau "hexBinary", sebagaimana mewajibkan. Untuk Skema time XML dan date jenis data, gunakan DateTime jenis dan terapkan SoapAttributeAttribute dengan DataType yang diatur ke "tanggal" atau "waktu".

Untuk setiap jenis data Skema XML yang dipetakan ke string, terapkan SoapAttributeAttribute dengan propertinya DataType yang diatur ke jenis data Skema XML. Perhatikan bahwa ini tidak mengubah format serialisasi, hanya skema untuk anggota.

Nota

Properti peka huruf besar/kecil, jadi Anda harus mengaturnya persis ke salah satu jenis data Skema XML.

Nota

Meneruskan data biner sebagai elemen XML lebih efisien lalu meneruskannya sebagai atribut XML.

Untuk informasi selengkapnya tentang tipe data Skema XML, lihat dokumen World Wide Consortium bernama XML Schema Bagian 2: Datatypes](https://www.w3.org/TR/xmlschema-2/).
