我在我的代码中遇到了命名空间的问题。我想要的是下面的XML:
<?xml version="1.0" encoding="utf-8"?>
<ClassToSerialize Type="Customer" Name="Some Name" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.123.org/namespace C:\Schema\ClassToSerialize.xsd"
xmlns:Test="http://www.Test.org/" xmlns="http://www.nrf-arts.org/namespace">
<Address>
<Line1>Addr1</Line1>
<Line2>Addr2</Line2>
</Address>
</ClassToSerialize>
What I'm getting is this XML:
<?xml version="1.0" encoding="utf-8"?>
<ClassToSerialize xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:schemaLocation="http://www.123.org/namespace C:\Schema\ClassToSerialize.xsd"
xmlns:Test="http://www.Test.org/" xmlns:xmlns="http://www.nrf-arts.org/namespace" Type="Customer" Name="Some Name">
<Address>
<Line1>Addr1</Line1>
<Line2>Addr2</Line2>
</Address>
</ClassToSerialize>
主要区别如下:
1. xmlns:schemaLocation= needs to be xsi:schemaLocation=
2. xmlns:xmlns= needs to be xmlns=
3. Attributes Order, I would prefer the Attributes to be presented before the namespace attributes (This is not a big Issue, just nice to have)
目前我正在做的是将1和2中序列化字符串中的值替换为我想要的值,这是一个可行的 hack,但我怀疑是否有一种方法可以修改命名空间代码以在该点处执行此操作?
以下是我正在使用的代码,如何更改 GetNameSpace() 以满足我在1和2点中所需的要求?同时,我能否重新排序属性?
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ClassToSerialize myInstance = new ClassToSerialize();
myInstance.Type = "Customer";
myInstance.Name = "Some Name";
myInstance.AddressField = new Address("Addr1", "Addr2");
String sString = SerializeObject<ClassToSerialize>(myInstance, GetNameSpace());
//Hack to achieve what I want from namespaces
sString = sString.Replace("xmlns:schemaLocation=", "xsi:schemaLocation=");
sString = sString.Replace("xmlns:xmlns=", "xmlns=");
}
private XmlSerializerNamespaces GetNameSpace()
{
XmlSerializerNamespaces xsNS = new XmlSerializerNamespaces();
xsNS.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
xsNS.Add("xmlns", "http://www.nrf-arts.org/namespace");
xsNS.Add("schemaLocation", "http://www.123.org/namespace C:\\Schema\\ClassToSerialize.xsd");
xsNS.Add("Test", "http://www.Test.org/");
return xsNS;
}
public static string SerializeObject<X>(X toSerialize, XmlSerializerNamespaces xmlNameSpace)
{
string strRetVal = "";
try
{
XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType());
StringWriter textWriter = new StringWriter();
using (StringWriter writer = new Utf8StringWriter())
{
xmlSerializer.Serialize(writer, toSerialize, xmlNameSpace);
strRetVal = writer.ToString();
}
}
catch (Exception ex)
{
string strError = ex.ToString();
}
return strRetVal;
}
}
public class Utf8StringWriter : StringWriter
{
public override Encoding Encoding
{
get { return Encoding.UTF8; }
}
}
public class ClassToSerialize
{
[XmlAttribute()]
public string Type { get; set; }
[XmlAttribute()]
public string Name { get; set; }
[XmlElement("Address")]
public Address AddressField { get; set; }
}
public class Address
{
[XmlElement, DefaultValue("")]
public string Line1 { get; set; }
[XmlElement, DefaultValue("")]
public string Line2 { get; set; }
public Address()
{
}
public Address(string L1, string L2)
{
Line1 = L1;
Line2 = L2;
}
}
