反序列化Xml文档没有结果

Question

I'm having some difficulties de-serializing an Xml document I have. See small complete sample of doc below:

<?xml version="1.0" encoding="utf-8" ?>
<MailClient>
<Client Id="Outlook.com">
    <Property Supported="false" Category="Responsive" Name="@media"><![CDATA["@media"]]></Property>
    <Property Supported="false" Category="Selectors" Name="*"><![CDATA["*"]]></Property>
    <Property Supported="false" Category="Selectors" Name="ElementSelector"><![CDATA["E"]]></Property>
    <Property Supported="false" Category="Selectors" Name="[=]"><![CDATA["[=]"]]></Property>
    <Property Supported="false" Category="Selectors" Name="[~=]"><![CDATA["[~=]"]]></Property>
    <Property Supported="false" Category="Selectors" Name="[^=]"><![CDATA["[^=]"]]></Property>
    <Property Supported="false" Category="Selectors" Name="[$=]"><![CDATA["[$=]"]]></Property>
    <Property Supported="false" Category="Selectors" Name="[*=]"><![CDATA["[*=]"]]></Property>
</Client>
</MailClient>

The associated classes look like this:

[Serializable, XmlRoot("Client"), XmlType("Client")]
public class MailClient
{
    [XmlElement("Client")]
    public List<CssRule> CssRules { get; set; }

    public MailClient()
    {
        CssRules = new List<CssRule>();
    }
}

[XmlType("Property")]
public class CssRule
{
    [XmlAttribute("Name")]
    public string Name { get; set; }
    [XmlAttribute("Category")]
    public string Category { get; set; }
    [XmlAttribute("Supported")]
    public bool IsSupported{ get; set; }

    public CssRule(){}
}

And the de-serializing is done with:

XmlSerializer serializer = new XmlSerializer(typeof(MailClient));
FileStream xmlFile = new FileStream(ConfigFile, FileMode.Open);
MailClient clients = (MailClient)serializer.Deserialize(xmlFile);

I was getting an exception There is an error in XML document (2, 2). relating to the MailClient element: {"<MailClient xmlns=''> was not expected."} . So I passed in a xml root attribute:

XmlSerializer serializer = new XmlSerializer(typeof(MailClient), 
new XmlRootAttribute("MailClient"));

Which seemed to correct the problem. clients now contains a single client but none of the propertys have been populated, that is to say category , name etc... all remain empty.

Can anyone see where I've gone wrong here? At this point I'm beginning to think it might be quicker for me to just use Linq to Xml rather than trying to de-serialize this

Answer 1

In your MailClient class, you have XmlRoot("Client") . Change that to the actual root element name, specifically XmlRoot("MailClient") . That way, you don't have to use the XmlRootAttribute in code.

For collections, you should use the XmlArray and XmlArrayItem attributes.

And where you are using XmlType attributes, you should be using XmlElement attributes.
