Contoh

Contoh berikut menserialisasi kelas bernama Group. SoapTypeAttribute diterapkan ke kelas , dengan TypeName diatur ke "SoapGroupType". yang SoapTypeAttribute juga ditimpa, mengubah menjadi TypeName "Tim". Kedua versi diserialisasikan, menghasilkan dua file: SoapType.xml dan SoapType2.xml.

Keterangan

Kelas SoapTypeAttribute milik keluarga atribut yang mengontrol bagaimana XmlSerializer serialisasi atau deserialisasi objek sebagai XML SOAP yang dikodekan. XML yang dihasilkan sesuai dengan bagian 5 dari dokumen World Wide Web Consortium, Simple Object Access Protocol (SOAP) 1.1. Untuk daftar lengkap atribut serupa, lihat Atribut yang Mengontrol Serialisasi SOAP yang Dikodekan.

Untuk membuat serial objek sebagai pesan SOAP yang dikodekan, buat XmlSerializer menggunakan yang XmlTypeMapping dibuat dengan ImportTypeMapping metode SoapReflectionImporter kelas .

hanya SoapTypeAttribute dapat diterapkan pada deklarasi kelas.

Properti IncludeInSchema menentukan apakah jenis elemen XML yang dihasilkan disertakan dalam dokumen Skema XML (.xsd) untuk aliran XML yang dihasilkan. Untuk melihat skema, kompilasi kelas ke dalam file DLL. Teruskan file yang dihasilkan sebagai argumen ke Xml Schema Definition Tool (Xsd.exe). Alat ini menghasilkan Skema XML untuk aliran XML yang dihasilkan saat kelas diserialisasikan oleh instans XmlSerializer kelas.

Mengatur namespace layanan yang berbeda menyebabkan Xsd.exe menulis file skema (.xsd) yang berbeda untuk aliran XML yang dihasilkan saat kelas diserialisasikan.

Konstruktor

Nama	Deskripsi
SoapTypeAttribute()	Menginisialisasi instans baru dari kelas SoapTypeAttribute.
SoapTypeAttribute(String, String)	Menginisialisasi instans SoapTypeAttribute baru kelas dan menentukan nama dan namespace XML dari jenis tersebut.
SoapTypeAttribute(String)	Menginisialisasi instans SoapTypeAttribute baru kelas dan menentukan nama jenis XML.

Properti

Nama	Deskripsi
IncludeInSchema	Mendapatkan atau menetapkan nilai yang menunjukkan apakah akan menyertakan jenis dalam dokumen Skema XML yang dikodekan SOAP.
Namespace	Mendapatkan atau mengatur namespace dari jenis XML.
