获取XML文件的属性值

我遇到了XML问题,并在XML文件上写了一些信息。
我有几个描述我的XML的xsd文件。我用"xsd/c testfile1.xsd testFile2.xsd..."等创建了一个大的.cs文件。一切都很好看,看起来不错。
但是,如果我采用一个创建的类,即testfile1.xsd,它看起来像 "<xs:complexType name="Header">"并且在那个内部有一些普通的xs:元素和东西,但是这个:"<xs:attribute name="version" default="1.0.0.0"/>"。这被翻译为:

"public Header() {
 this.versionField = "1.0.0.0";}" 

在生成的类'Header'中。它也得到了这个领域:private string versionField;

。 (当然还有其他几个私人领域,但这些领域都很好。)所以我创建了所有类的实例,用数据填充它们并将其写成XML文件:

 - XmlSerializer XmlSerRoot = new XmlSerializer(typeof(RootInformation))
   (the root of my xml!) 
 - StringWriterWithEncoding strWriter = new StringWriterWithEncoding(Encoding.GetEncoding("iso-8859-1"));
 - XmlDocument documentInXML = new XmlDocument();
 - XmlSerRoot.Serialize(strWriter, rootInformation); (Here is the XML, filled with values, and the Header.version got the value 1.0.0.0) 
 - string XmlString;
 - XmlString = strWriter.ToString(); (Here I can look at the created xml when debugging in VS and now the version-information is gone)
 - documentInXML.LoadXml(XmlString);
 - documentInXML.Save(myPath);


但是当我查看xml文件时,<Header>没有版本。我希望我看起来像:<Header version="1.0.0.0">
我甚至尝试在代码中执行此操作:

Header header = new Header(); 
header.version = header.version; 
and
with header.version = "1.0.0.0";

但是标签中还没有版本文本。所有其他标签都有其价值。只是这<Header>松了这些额外的信息。
有人有小费吗?有很多地方我需要这个工作。其他一切都很好。

这是一段示例代码:

using System.Xml;
namespace TestAppXML
{
    class Program
    {
        static void Main(string[] args)
        {
            RootInfo rootInfo = new RootInfo();
            rootInfo.RootText = "This is the Root!";
            Header header = new Header();
            header.TestHeader = "This is HeaderText!";
            rootInfo.Header = header;
            XmlSerializer XmlSerRoot = new XmlSerializer(typeof(RootInfo));
            StringWriterWithEncoding strWriter = new StringWriterWithEncoding(Encoding.GetEncoding("iso-8859-1"));
            XmlDocument documentInXML = new XmlDocument();
            XmlSerRoot.Serialize(strWriter, rootInfo);
            string XmlString;
            XmlString = strWriter.ToString();
            documentInXML.LoadXml(XmlString);
            strWriter.Close();
            documentInXML.Save(@"C:\TestXml.xml");
        }
    }

没关系,我想我知道这个问题。这是因为这个xsd.exe为这些字段创建了“DefaultValueAttribute”。这会阻止此字段位于xml中。也许有些xsd-switch可以做到这一点,我不知道......
