Question

存在一个名为XSD的标准（XML Schema Definition），它将类定义生成为XML格式。生成的类可以使用以下语言：VB, C#, JS, VJS, C++

如何实现从此XML重新创建特定语言的类？

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>

***有些XML文件可能包含更多内容，我想自动生成代码，这个XML只是用来提供一个简单的例子。

Answer 1

如果要解析XML文件并在.net中创建自动生成的类，则应使用xsd.exe工具执行此操作，该工具是Visual Studio中Dev工具的一部分。

您需要打开Dev Command Prompt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为here，但这可能会根据安装位置而改变。

在命令提示符中运行以下命令：

xsd'yourfilename'.xml

实施例：这将在目录文件夹中自动生成XML Scheme File'yourfilename'.xsd。

接下来，我们希望使用我们选择的语言使用自动创建的XSD文件自动生成代码：

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

实施例： 这将从XSD文件创建一个自动生成.NET类，该类将包含在名为“yourfilename”.vb的文件中。

然后，您只需将您的课程文件添加到项目中即可。

我选择VB但您可以选择：'CS'，'VB'，'JS'，'VJS'或'CPP'。

这是创建的VB文件中的代码：
