如何基于 XSD/XML 文件自动生成特定 .NET 语言的代码

How to auto-generate code in specific .NET language based on an XSD/XML file

我需要将 XML 文件中的数据序列化为对象。此对象 class 是在 XML 中定义的。有许多不同的 XML 文件，我想自动生成定义 class 的代码以节省时间并避免人为错误。自动生成的 class 可能是这些语言：VB、C#、JS、VJS、C++

我怎样才能将这个 XML 代码自动生成为特定语言？

XML 文件的示例如下：

<?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>

***有很多 XML 文件，我想从中自动生成代码，这个 XML 只是用来提供一个简单的例子。

如果你想解析一个 XML 文件并在 .net 中创建一个 auto-generated class 那么你应该使用 xsd.exe 工具来完成Visual Studio 中开发工具的一部分。

您需要打开 Dev 命令提示符才能 运行 该工具。 Open Command Prompt from inside Visual Studio

VS 2013 命令提示符的默认位置是 here，但这可能会根据安装位置而改变。

在命令提示符 运行 中执行以下命令：

xsd 'yourfilename'.xml

示例： 这将auto-generate目录文件夹中的XML方案文件'yourfilename'.xsd。

接下来，我们要 auto-generate 使用我们选择的语言的 auto-created XSD 文件的代码：

xsd 'yourfilename'.xsd /classes /language:vb

示例： 这将从 XSD 文件创建一个 auto-generate .NET class，该文件将包含在名为 'yourfilename'.vb.[ 的文件中=48=]

然后您只需将包含 class 的文件添加到您的项目中即可。

我选择 VB，但你可以 select：'CS'、'VB'、'JS'、'VJS' 或 'CPP' .

这是创建的 VB 文件中的代码：
