我正在寻找反序列化 xml 的快速方法，其中包含特殊字符，如 ö。

我正在使用 XMLReader，但它无法反序列化此类字符。

有什么建议吗？

编辑：我正在使用 C#。代码如下：

XElement element =.. //has the xml
XmlSerializer serializer =   new XmlSerializer(typeof(MyType));
XmlReader reader = element.CreateReader();
Object o= serializer.Deserialize(reader);

我猜你遇到了编码问题，不是XMLReader在XmlSerializer.

您可以在以下代码段中使用XmlTextWriterUTF8 编码和XmlSerializer类似的编码（请参阅下面的通用方法以更好地实现它）。与变音符号 (äöü) 和其他特殊字符配合使用效果很好。

class Program
{
    static void Main(string[] args)
    {
        SpecialCharacters specialCharacters = new SpecialCharacters { Umlaute = "äüö" };

        // serialize object to xml

        MemoryStream memoryStreamSerialize = new MemoryStream();
        XmlSerializer xmlSerializerSerialize = new XmlSerializer(typeof(SpecialCharacters));
        XmlTextWriter xmlTextWriterSerialize = new XmlTextWriter(memoryStreamSerialize, Encoding.UTF8);

        xmlSerializerSerialize.Serialize(xmlTextWriterSerialize, specialCharacters);
        memoryStreamSerialize = (MemoryStream)xmlTextWriterSerialize.BaseStream;

        // converts a byte array of unicode values (UTF-8 enabled) to a string
        UTF8Encoding encodingSerialize = new UTF8Encoding();
        string serializedXml = encodingSerialize.GetString(memoryStreamSerialize.ToArray());

        xmlTextWriterSerialize.Close();
        memoryStreamSerialize.Close();
        memoryStreamSerialize.Dispose();

        // deserialize xml to object

        // converts a string to a UTF-8 byte array.
        UTF8Encoding encodingDeserialize = new UTF8Encoding();
        byte[] byteArray = encodingDeserialize.GetBytes(serializedXml);

        using (MemoryStream memoryStreamDeserialize = new MemoryStream(byteArray))
        {
            XmlSerializer xmlSerializerDeserialize = new XmlSerializer(typeof(SpecialCharacters));
            XmlTextWriter xmlTextWriterDeserialize = new XmlTextWriter(memoryStreamDeserialize, Encoding.UTF8);

            SpecialCharacters deserializedObject = (SpecialCharacters)xmlSerializerDeserialize.Deserialize(xmlTextWriterDeserialize.BaseStream);
        }
    }
}

[Serializable]
public class SpecialCharacters
{
    public string Umlaute { get; set; }
}

我个人使用以下通用方法来序列化和反序列化 XML 和对象，并且还没有任何性能或编码问题。

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;
}

public static T DeserializeXmlToObject<T>(string xml)
{
    using (MemoryStream memoryStream = new MemoryStream(StringToByteArrayUtf8(xml)))
    {
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));

        using (StreamReader xmlStreamReader = new StreamReader(memoryStream, Encoding.UTF8))
        {
            return (T)xmlSerializer.Deserialize(xmlStreamReader);
        }
    }
}

public static string ByteArrayToStringUtf8(byte[] value)
{
    UTF8Encoding encoding = new UTF8Encoding();
    return encoding.GetString(value);
}

public static byte[] StringToByteArrayUtf8(string value)
{
    UTF8Encoding encoding = new UTF8Encoding();
    return encoding.GetBytes(value);
}

对我有用的方法类似于@martin-buberl 的建议：

public static T DeserializeXmlToObject<T>(string xml)
{
    using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
    {
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        StreamReader reader = new StreamReader(memoryStream, Encoding.UTF8);
        return (T)xmlSerializer.Deserialize(reader);
    }
}

-1 
    [XmlElement(ElementName = "Profiles")]
    //public ProfilesType[] Profiles { get; set; }
    public Profiles Profiles { get; set; }

试过上面的东西吗？

我没有检查过，但这突然出现在我的脑海中。我设法对具有åäö等的数据进行反序列化。你不是在谈论标记名吗？
