[英]Get attribute values to the XML-File
I got a issue with XML, and write some information on a XML-file. 我遇到了XML问题,并在XML文件上写了一些信息。
I got several xsd-files describing my XML. 我得到了几个描述我的XML的xsd文件。 I created one big .cs-file with "xsd/c testfile1.xsd testFile2.xsd..."
etc. And everything went nice and looks good. 我用"xsd/c testfile1.xsd testFile2.xsd..."
等创建了一个大的.cs文件。一切正常,看起来不错。
But if I take one created class ie testfile1.xsd, it looks like "<xs:complexType name="Header">"
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"/>"
. 但是,如果我使用一个创建的类,即testfile1.xsd,它看起来像"<xs:complexType name="Header">"
并且在该类中有一些普通的xs:element和其他东西,但也有: "<xs:attribute name="version" default="1.0.0.0"/>"
。 This is translated to: 这被翻译为:
"public Header() {
this.versionField = "1.0.0.0";}"
in the generated class 'Header'. 在生成的类“ Header”中。 And it got as well this field: private string versionField;
它也得到了这个字段: private string versionField;
. 。 (There is of course a couple of other private fields as well, but those works good.). (当然也有其他两个私有领域,但是它们很好用。)。 So I create instances of all classes, fill them with data and write it as an XML-file with this: 因此,我创建了所有类的实例,并用数据填充它们,并使用以下代码将其编写为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);
But when I look at the xml-file this <Header>
is not have anything like version. 但是,当我查看xml文件时,该<Header>
没有类似的版本。 I want i to look like: <Header version="1.0.0.0">
我希望我看起来像: <Header version="1.0.0.0">
I even tried to do it in code like: 我什至尝试用以下代码来做到这一点:
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. 但是标记中仍然没有版本文本。 All other tags got their value. 所有其他标签都具有其价值。 Just this <Header>
loose this extra information. 只是这个<Header>
松散了这些额外的信息。
Does someone got a tip? 有人给小费吗? There is a lot of places I need this to work. 我在很多地方都需要这项工作。 Everything else is just working fine. 其他一切都很好。

Here is an piece of example-code: 这是一段示例代码:
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");
}
}

}

}
class StringWriterWithEncoding : StringWriter
{
private Encoding MyEncoding;
public StringWriterWithEncoding(Encoding encoding)
: base()
{MyEncoding = encoding;}
public override Encoding Encoding
{
get{return MyEncoding;}
}
}
}
Nevermind, I think I knov the issue. 没关系,我想我知道这个问题。 It's because this xsd.exe creates 'DefaultValueAttribute' for those fields. 这是因为此xsd.exe为这些字段创建了“ DefaultValueAttribute”。 That prevent this field to be in the xml. 这样可以防止该字段位于xml中。 Maybe some xsd-switch could have done that, I dunno... 也许有些xsd-switch可以做到这一点,我不知道...
