我有以下扩展方法来序列化我的类......
public static string SerializeToXml<T>(this object obj)
{
XDocument doc = new XDocument();
XmlSerializer ser = new XmlSerializer(typeof(T));
using (var writer = doc.CreateWriter())
{
ser.Serialize(writer, obj);
}
return doc.ToString();
}
这似乎工作正常,并为我的序列化对象返回以下字符串:
<AuthenticatedUser xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Username>mark</Username>
<UserID>4</UserID>
<Roles>
<string>AuthenticatedUsers</string>
</Roles>
<IsValid>false</IsValid>
</AuthenticatedUser>
但是,当我尝试使用下面的方法反序列化此字符串时,我收到此错误:
{"The encoding style '<AuthenticatedUser xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">\r\n <Username>mark</Username>\r\n <UserID>4</UserID>\r\n <Roles>\r\n <string>AuthenticatedUsers</string>\r\n </Roles>\r\n <IsMale>false</IsMale>\r\n</AuthenticatedUser>' is not valid for this call because this XmlSerializer instance does not support encoding. Use the SoapReflectionImporter to initialize an XmlSerializer that supports encoding."}
...方法
public static T DeserializeFromXml<T>(this string xml)
{
var element = XElement.Parse(xml);
XmlSerializer ser = new XmlSerializer(typeof(T));
using (var reader = element.CreateReader())
{
return (T)ser.Deserialize(reader, xml);
}
}
因此,在我阅读错误消息后,我更改了deserialize方法以使用SoadReflectionImporter ....
public static T DeserializeFromXml<T>(this string xml)
{
var element = XElement.Parse(xml);
SoapReflectionImporter soap = new SoapReflectionImporter();
var mapping = soap.ImportTypeMapping(typeof(T));
XmlSerializer ser = new XmlSerializer(mapping);
using (var reader = element.CreateReader())
{
return (T)ser.Deserialize(reader, xml);
}
}
但是我现在得到这个错误......
{"The encoding style '<AuthenticatedUser xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">\r\n <Username>mark</Username>\r\n <UserID>4</UserID>\r\n <Roles>\r\n <string>AuthenticatedUsers</string>\r\n </Roles>\r\n <IsValid>false</IsValid>\r\n</AuthenticatedUser>' is not valid for this call. Valid values are 'http://schemas.xmlsoap.org/soap/encoding/' for SOAP 1.1 encoding or 'http://www.w3.org/2003/05/soap-encoding' for SOAP 1.2 encoding."}
有谁知道我哪里出错了,以及如何成功地反序列化这个字符串?

问题是您正在调用的Deserialize方法的重载:
return (T)ser.Deserialize(reader, xml);
调用中的xml参数指定编码样式,但在这种情况下,您将从序列化传递xml。只需删除第二个参数,然后使用阅读器调用反序列化,它应该可以正常工作:
return (T)ser.Deserialize(reader);

XElement.CreateReader()
不会返回XDeclaration
。
相反,请尝试从XmlReader
创建StringReader
。

您需要Parse(xml)调用和reader元素吗?既然你有字符串,你不能只是反序列化字符串吗?首先转换为字节...
byte [] bytes = Encoding.Unicode.GetBytes(xml);
MemoryStream mem = new MemoryStream(bytes);
returnValue = (T)ser.Deserialize(mem);
