c# - 使用 XSD 文件在 C# 中生成 XML 文件

Question

我正在尝试使用现有的 XSD 文件通过 C# 构建一个新的 XML 文件。这是 xsd 文件:

<?xml version="1.0" encoding="utf-8"?>

</xsd:schema>

我做了以下事情来创建 XML 文件:

• 用xsd.exe制作了一个类
• 我将类(class)添加到我的项目中

• 编写了以下函数:

                  var data = new KilometerUploadKilometerRegistration 
              {
              ChassisNumber = huidigefactuur.Wagen.Chassisnummer,
              KilometerStatus = huidigefactuur.KMStand.ToString(),
              TypeOfData = "120",
  
              };
              var serializer = new XmlSerializer(typeof(KilometerUploadKilometerRegistration));
              using (var stream = new StreamWriter("C:\\test.xml"))
                  serializer.Serialize(stream, data);
  

正在创建 XML 文件，但我需要从 KilometerUpload 节点开始，而不是 KilometerRegistration 节点，我该怎么做？

这是我用上面使用的代码得到的输出:

<?xml version="1.0" encoding="UTF-8"?>

-<KilometerUploadKilometerRegistration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<ChassisNumber>WVWZZZ3CZ7E201402</ChassisNumber>

<KilometerStatus>78000</KilometerStatus>

<TypeOfData>120</TypeOfData>

</KilometerUploadKilometerRegistration>

谢谢!

我找到了答案:

• 我不需要更改 xsd.exe 生成的类

这是我结束的代码，现在可以完美运行了:

                foreach (Factuur huidigeFactuur2 in e.SelectedObjects)
            {
                XmlSerializer serializer2 = new XmlSerializer(typeof(KilometerUpload));
                TextWriter writer = new StreamWriter(@"C:\test2.xml");

                string chassisnummer = huidigeFactuur2.Wagen.Chassisnummer;
                string kilometerstatus = huidigeFactuur2.KMStand.ToString();

                KilometerUpload item = new KilometerUpload
                {
                    KilometerRegistration = new KilometerUploadKilometerRegistration[] { new KilometerUploadKilometerRegistration{ ChassisNumber = chassisnummer , TypeOfData = "120", KilometerStatus = kilometerstatus} },
                };

                serializer2.Serialize(writer, item);
