获取XML文件的属性值 [英] Get attribute values to the XML-File
问题描述
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创建了一个大的.cs文件。 xsd ...... 等等。一切都很顺利，看起来不错。
但是如果我使用一个创建的类，即testfile1.xsd，它看起来像< xs：complextype name =Headerxmlns：xs =＃unknown>在那一个里面有一些普通的xs：元素和东西，但是这个：< xs：attribute name =versiondefault =1.0.0.0>。这被翻译为：
public Header（）{
this.versionField =1.0.0.0;}
生成的类''标题''。它也得到了这个字段：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：
但是当我查看xml文件时这个< ;页眉和GT;没有版本的东西。我希望我看起来像：< Header version =1.0.0.0>
这是一段示例代码：
使用系统;
使用 System.Collections.Generic;
使用 System.Linq;
使用 System.Text;
使用 System.Xml.Serialization;
使用 System.IO;
使用 System.Xml;
命名空间 TestAppXML
{
class 程序
{
静态 void Main（ string [] args）
{
RootInfo rootInfo = new RootInfo（）;
rootInfo.RootText = 这是Root！;
标头标头= 新标头（）;
header.TestHeader = 这是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：\ TestMml.xml）;
}
}

{
私人编码MyEncoding;
public StringWriterWithEncoding（编码编码）
： base （）
{MyEncoding = encoding;}
public 覆盖编码编码
{
获取 {返回 MyEncoding;}
}
}
}
我甚至尝试用以下代码来做：
< pre lang =c＃>标题标题= new 标题（）;
header.version = header.version;
和
，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。只是这个< Header>松散这些额外的信息。
有人得到了小费吗？有很多地方我需要这个工作。其他一切都运转正常。
问候，

< blockquote>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......
I got a issue with XML, and write some information on a XML-file.
I got several xsd-files describing my XML. I created one big .cs-file with
"xsd/c testfile1.xsd testFile2.xsd..." etc. And everything went nice and looks good.
But if I take one created class i.e. testfile1.xsd, it looks like "<xs:complextype name="Header" xmlns:xs="#unknown">" and inside that one there is this some ordinary xs:element and stuff, but also this: "<xs:attribute name="version" default="1.0.0.0">". This is translated to:
"public Header() {
this.versionField = "1.0.0.0";}"
in the generated class ''Header''. And it got as well this field: private string versionField;
. (There is of course a couple of other private fields as well, but those works good.). So I create instances of all classes, fill them with data and write it as an XML-file with this:
But when I look at the xml-file this <Header> is not have anything like version. I want i to look like: <Header version="1.0.0.0">
Here is an piece of example-code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;
using System.IO;
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");
}
}

{
private Encoding MyEncoding;
public StringWriterWithEncoding(Encoding encoding)
: base()
{MyEncoding = encoding;}
public override Encoding Encoding
{
get{return MyEncoding;}
}
}
}
I even tried to do it in code like:
Header header = new Header();
header.version = header.version;
and
with header.version = "1.0.0.0";
But still it''s no version-text in the tag. All other tags got their value. Just this <Header> loose this extra information.
Does someone got a tip? There is a lot of places I need this to work. Everything else is just working fine.

Nevermind, I think I knov the issue. It''s because this xsd.exe creates ''DefaultValueAttribute'' for those fields. That prevent this field to be in the xml. Maybe some xsd-switch could have done that, I dunno...
