XML序列化，添加命名空间，添加声明头，添加节点前缀
xml序列化⽅法
///<summary>
///将⼀个对象序列化为XML字符串
///</summary>
///<param name="o">要序列化的对象</param>
///<param name="encoding">编码⽅式</param>
///<returns>序列化产⽣的XML字符串</returns>
public static string XmlSerialize(object o, Encoding encoding)
{
if (o == null)
throw new ArgumentNullException("o");
if (encoding == null)
throw new ArgumentNullException("encoding");
string xml = "";
try
{
using (MemoryStream stream = new MemoryStream())
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.Encoding = encoding;
//OmitXmlDeclaration表⽰不⽣成声明头，默认是false，OmitXmlDeclaration为true，会去掉<?xml version="1.0" encoding="UTF-8"?>
//settings.OmitXmlDeclaration = true;
XmlWriter writer = XmlWriter.Create(stream, settings);
//强制指定命名空间，覆盖默认的命名空间，可以添加多个，如果要在xml节点上添加指定的前缀，可以在跟节点的类上⾯添加[XmlRoot(Namespace = "/2001/XMLSchema-instance", IsNullable = false)]，Namespace指定哪            XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add("ceb", "v/ceb");
namespaces.Add("xsi", "/2001/XMLSchema-instance");
XmlSerializer serializer = new XmlSerializer(o.GetType());
serializer.Serialize(writer, o, namespaces);
writer.Close();
stream.Position = 0;
using (StreamReader reader = new StreamReader(stream, encoding))
{
xml = reader.ReadToEnd();
}
}
}
catch (Exception ex)
{
}
return xml;
}
对象属性：
[XmlRoot(Namespace = "v/ceb")]
public class CEB311Message
{
[XmlAttribute("guid")]
public string Guid { get; set; }
[XmlAttribute("version")]
public string Version { get; set; }
public Order Order { get; set; }
public BaseTransfer BaseTransfer { get; set; }
}
public class Order
{
public OrderHead OrderHead { get; set; }
[XmlElement("OrderList")]
public List<OrderList> OrderList { get; set; }
}
public class BaseTransfer
{
public string copCode { get; set; }
public string copName { get; set; }
public string dxpMode { get; set; }
public string dxpId { get; set; }
public string note { get; set; }
}
public class OrderHead
{
//......
}
public class OrderList
{
//......
}
序列化以后的xml报⽂：
<?xml version="1.0" encoding="utf-8"?>

CEB311Message类头上的[XmlRoot(Namespace = "v/ceb")]，Namespaces指定哪⼀个值，就可以添加对应命名空间的前缀
