我有以下类的对象:
public class Root
{
[XmlElement]
public BOMItems[] Row { get; set; }
}
public class BOMItems
{
[XmlElement("ITEMNO")]
public string ITEMNO { get; set; }
[XmlElement("USED")]
public string USED { get; set; }
[XmlElement("PARTSOURCE")]
public string PARTSOURCE { get; set; }
[XmlElement("QTY")]
public string QTY { get; set; }
}
我正尝试使用此方法将其序列化为XDocument
:
public XDocument TransformClassToXMLBOM(Root rt)
{
var serializer = new XmlSerializer(typeof(Root));
var sww = new StringWriter();
var settings = new XmlWriterSettings();
settings.ConformanceLevel = ConformanceLevel.Auto;
var writer = XmlWriter.Create(sww, settings);
serializer.Serialize(writer, rt);
var doc = new XDocument(
new XElement("Row",
new XElement("ITEMNO"),
new XElement("USED"),
new XElement("PARTSOURCE"),
new XElement("QTY")));
doc.Save(writer);
return doc;
}
我甚至尝试在new XElement("Row",
之前插入一个额外的元素:
var doc = new XDocument(
new XElement("Root",
new XElement("Row",...
我总是在这一行doc.Save(writer);
上面得到以下错误:
状态EndRootElement中的Token StartDocument将导致 XML文档无效。确保ConformanceLevel设置为 如果需要,设置为ConformanceLevel.Fragment或ConformanceLevel.Auto 写一个XML片段。
起初我以为我可能会错过一个XElement或者拼错了,但我找不到任何错误。我不知道如何查看writer
中的值来检查结果,所以我不知道如何找到解决方案。
我想结束这样的事情:
<Root>
<Row>
<ITEMNO>1</ITEMNO>
<USED>Y</USED>
<PARTSOURCE>BUY</PARTSOURCE>
<QTY>10</QTY>
</Row>
</Root>
如何找到问题的原因?达到预期结果的正确方法是什么?

查看Xml Serializable Generic Dictionary http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx 你可以为你的情况做几乎一样的事。
UPD 然后你可以使用像这样的标准序列化序列化你的类
public static string SerializeObjectToXml<T>(T obj)
{
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
xmlSerializer.Serialize(xmlTextWriter, obj);
memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
string xmlString = ByteArrayToStringUtf8(memoryStream.ToArray());
xmlTextWriter.Close();
memoryStream.Close();
memoryStream.Dispose();
return xmlString;
}
UPD2
public static string ByteArrayToStringUtf8(byte[] value)
{
UTF8Encoding encoding = new UTF8Encoding();
return encoding.GetString(value);
}

更清晰的方式:
[Serializable]
public class Root
{
[XmlElement("ITEMS")]
public BOMItem[] Row { get; set; }
}
[Serializable]
public class BOMItem
{
[XmlElement("ITEMNO")]
public string ITEMNO { get; set; }
[XmlElement("USED")]
public string USED { get; set; }
[XmlElement("PARTSOURCE")]
public string PARTSOURCE { get; set; }
[XmlElement("QTY")]
public string QTY { get; set; }
}
所以你可以像这样得到你的xml:
Root r1 = new Root();
r1.Row = new BOMItem[2];
r1.Row[0] = new BOMItem {ITEMNO = "1", PARTSOURCE = "11", QTY = "111", USED = "1111"};
r1.Row[1] = new BOMItem { ITEMNO = "2", PARTSOURCE = "22", QTY = "222", USED = "2222" };
MessageBox.Show(String.Format("Serialization result: {0}", SerializeObjectToXml(r1)));
