Help with serialization

[lallous]

Hello

I have the following XML string:

<?xml version="1.0" encoding="UTF-8"?>
<bool name="value" val="false" display="OFF" href="/value/"
xmlns="http://MyObj.org/ns/schema/1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://MyObj.org/ns/schema/1.0 /MyObj/xsd"/>

Then I assign it to a StringReader and deserialize it against the following
class:

[XmlRoot("bool")]
public class MyObjBool
{
[XmlAttribute("name")]
public string name;
[XmlAttribute("val")]
public bool val;
}

The code snippet is:

s1 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><?xml-stylesheet
type='text/xsl' href='/MyObj/xsl'?><bool name=\"value\" val=\"false\"
display=\"OFF\" href=\"/value/\" xmlns=\"http://MyObj.org/ns/schema/1.0\"
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"
xsi:schemaLocation=\"http://MyObj.org/ns/schema/1.0 /MyObj/xsd\"/>";

StringReader sr = new StringReader(s1);
XmlSerializer xs = new XmlSerializer(typeof(MyObjBool));

try
{
MyObjBool ob = (MyObjBool) xs.Deserialize(sr);
}
catch (Exception e)
{
msg(e.ToString());
}

Which is firing the following exception:

System.InvalidOperationException: There is an error in XML document (1,
92). ---> System.InvalidOperationException: <bool
xmlns='http://MyObj.org/ns/schema/1.0'> was not expected.

Why?

Why is it when I remove the xmlns attribute the DeSerialize works?

lallous,

With the XmlRoot attribute, you need to set the namespace as well for
the element. Your attribute declaration should look like this:

[XmlRoot(ElementName = "bool", Namespace =
"http://MyObj.org/ns/schema/1.0")]
public class MyObjBool

Hope this helps.
