ns1：C＃反序列化问题

Question

Below is the test code used to get the ns1: issue, I always get a object with nothing in it.

if I remove the two [XmlType] and [XmlRoot] it errors.

I am sure some one already should have faced the problem not getting the right term to search probably,

hope fully its a simple thing.

[XmlType(AnonymousType = true, Namespace = "http://itaintworking.com/test/")]
[XmlRoot(Namespace = "http://itaintworking.com/test/", IsNullable = false)]
public class Clients
{
    public string clientName { get; set; }
    public addressDetails addressDetails { get; set; }
}

public class addressDetails
{
    public int addressId { get; set; }
}

[Test(Description = "Serialization Exception")]
public void CheckDeserializer()
{
    var strXml =
        "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><ns1:Clients xmlns:ns1=\"http://itaintworking.com/test/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" ><clientName>hello</clientName><addressDetails><addressId>98989</addressId></addressDetails></ns1:Clients>";
    var x = XmlSerializer<Clients>.Deserialize(strXml);
    Assert.IsNotNull(x);
}

I am using some code which uses generics, there is another method defaulting to UTF8 encoding, and a null for the xmlReaderSetting.

/// <summary>
/// Deserializes a XML string into an object
/// </summary>
/// <param name="xml">The XML string to deserialize</param>
/// <param name="encoding">The encoding</param>
/// <param name="settings">XML serialization settings. <see cref="System.Xml.XmlReaderSettings"/></param>
/// <returns>An object of type <c>T</c></returns>
public static T Deserialize(string xml, Encoding encoding, XmlReaderSettings settings)
{
    if (string.IsNullOrEmpty(xml))
        throw new ArgumentException("XML cannot be null or empty", "xml");

    var xmlSerializer = new XmlSerializer(typeof(T));
    using (var memoryStream = new MemoryStream(encoding.GetBytes(xml)))
    {
        using (var xmlReader = XmlReader.Create(memoryStream, settings))
        {
            return (T)xmlSerializer.Deserialize(xmlReader);
        }
    }
}

It's not clear exactly how you would want this to be fixed.

As it currently stands in the XML, the clientName and addressDetails elements within the Clients element are not in the same namespace. So, one fix is:

[XmlType(AnonymousType = true, Namespace = "http://itaintworking.com/test/")]
[XmlRoot(Namespace = "http://itaintworking.com/test/", IsNullable = false)]
public class Clients
{
    [XmlElement(Namespace="")]
    public string clientName { get; set; }
    [XmlElement(Namespace = "")]
    public addressDetails addressDetails { get; set; }
}

Another fix might be to change the namespaces in the XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns1:Clients xmlns:ns1="http://itaintworking.com/test/"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <ns1:clientName>hello</ns1:clientName>
   <ns1:addressDetails>
       <ns1:addressId>98989</ns1:addressId>
   </ns1:addressDetails>
 </ns1:Clients>
