XMLSerialization-自定义根属性

Question

我正在研究一个项目，以将XML序列化并将其设置为Web服务。 根元素是高度定制的，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<eAction xmlns="http://www.action.org/standards/PC_Surety/action1/xml/" xmlns:cation="http://www.caction.org/standards/pc_go/xml/" xmlns:acme="http://www.ACME.org/standards/ACME1/xml/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

根有几个不同的名称空间，并且xsd属性不存在。

我一直在尝试解决如何添加额外的名称空间属性的问题，并且也许串行化不是解决问题的方法。

到目前为止，我有一个带有一组简单的要序列化的测试程序：

private void button1_Click(object sender, EventArgs e)
{
  XmlSerializer xmlSerialize = new XmlSerializer(typeof(eAction));
  TextWriter txtWriter = new StreamWriter(@"c:\actionout.xml");
  eAction eActionItem = new eAction();

  xmlSerialize.Serialize(txtWriter, eActionItem);
}

[XmlRoot(ElementName="eAction")]
public class eAction
{
  public string Name = string.Empty;
  public string Street1 = string.Empty;
  public string Street2 = string.Empty;
  public string City = string.Empty;
  public string State = string.Empty;
  public string PostalCode = string.Empty;

  public OtherInformation OtherInformation = new OtherInformation();
}

public class OtherInformation
{
  public string DateOfBirth = string.Empty;
  public string SSN = string.Empty;
}

运行此命令将创建以下xml：

<?xml version="1.0" encoding="utf-8"?>
<eAction xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Name />
  <Street1 />
  <Street2 />
  <City />
  <State />
  <PostalCode />
  <OtherInformation>
    <DateOfBirth />
    <SSN />
  </OtherInformation>
</eAction>

有没有添加我需要的属性的好方法？

编辑：接受的答案解决了问题。 还有一个问题-我还必须添加：

xsi:schemaLocation="http://www.action.org/standards/PC_Surety/action1/xml/ standardsFile.xsd"

是否可以将其添加为命名空间，但用xsi代替xmlns，还是可以使用其他方法添加此属性？

我认为这可能会满足您的需求。 你说得对，:)。

你的班：

[XmlRoot(ElementName = "eAction", Namespace = "http://www.action.org/standards/PC_Surety/action1/xml/")]
public class eAction
{
    [XmlAttribute(Namespace = XmlSchema.InstanceNamespace)]
    public string schemaLocation = "http://www.action.org/standards/PC_Surety/action1/xml/standardsFile.xsd";
    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();

    public eAction()
    {
        xmlns.Add("cation", "http://www.caction.org/standards/pc_go/xml/");
        xmlns.Add("acme", "http://www.ACME.org/standards/ACME1/xml/");
        xmlns.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
    }

    public string Name = string.Empty;
    public string Street1 = string.Empty;
    public string Street2 = string.Empty;
    public string City = string.Empty;
    public string State = string.Empty;
    public string PostalCode = string.Empty;

    public OtherInformation OtherInformation = new OtherInformation();
}

public class OtherInformation
{
    public string DateOfBirth = string.Empty;
    public string SSN = string.Empty;
}

使用示例：

        private static void button1_click()
    {
        var xmlSerializer = new XmlSerializer(typeof(eAction));
        using (var txtWriter = new StreamWriter(@"C:\temp\actionout.xml"))
        {
            var eActionItem = new eAction();
            xmlSerializer.Serialize(txtWriter, eActionItem);
        }
    }
