Как автоматически сгенерировать код класса на конкретном языке .NET из XSD / XML?
Существует стандарт под названием XSD (Определение схемы XML), которое создает определение класса в формате XML. Созданный класс может быть на следующих языках: VB, C#, JS, VJS, C++
Как я могу добиться воссоздания классов из этого XML на конкретном языке?
Пример файла XML может быть следующим:
<?xml version="1.0" encoding="utf-8" ?>
<MyFile VersionProduct="7.0" VersionCreate="7.00" VersionFile="7.00">
<MyTable Size="20">
<StandardTable Type="TXT">
<MyRecord Priority="1" Size="0" Length="350" Weight="270" Age="40" Ref="80"/>
<MyRecord Priority="100" Size="0" Length="27080" Weight="27000" Age="40" Ref="80"/>
</StandardTable>
</MyTable>
<MyTable Size="28">
<StandardTable Type="TXT">
<MyRecord Priority="1" Size="0" Length="350" Weight="270" Age="40" Ref="80"/>
<MyRecord Priority="100" Size="0" Length="27080" Weight="27000" Age="40" Ref="80"/>
</StandardTable>
<StandardTable Type="TRT">
<MyRecord Priority="100" Size="0" Length="980" Weight="900" Age="40" Ref="0"/>
</StandardTable>
</MyTable>
</MyFile>
*** Могут быть файлы XML с гораздо большим содержанием, из которого я хотел бы автоматически генерировать код, этот XML был просто использован для предоставления простого примера.
Решение
Если вы хотите проанализировать XML-файл и создать автоматически сгенерированный класс в .net, вы должны сделать это с помощью инструмента xsd.exe, который входит в состав инструментов Dev в Visual Studio.
Вам нужно будет открыть командную строку Dev, чтобы запустить инструмент.
Откройте командную строку из Visual Studio
Расположение по умолчанию для командной строки для VS 2013 Вот, но это может измениться в зависимости от места установки.
В командной строке выполните следующие команды:
xsd ‘yourfilename’.xml
Пример:
Это автоматически сгенерирует файл схемы XML ‘yourfilename’.xsd в папке каталога.
Далее мы хотим автоматически сгенерировать код, используя автоматически созданный XSD-файл на выбранном нами языке:
xsd ‘yourfilename’.xsd / classes / language: vb
Пример:
Это создаст автоматически сгенерированный класс .NET из файла XSD, который будет содержаться в файле с именем ‘yourfilename’.vb.
Затем вы можете просто добавить файл с вашим классом в ваш проект.
Я выбираю VB, но вы можете выбрать: «CS», «VB», «JS», «VJS» или «CPP».
Это код в файле VB, который был создан:
