Re: Error reflecting type when trying to serialize

Hi, thanks for the response.

Unfortunately the way the XML is, I have to create two separate tags (plyrdets) but they have different contents. I understand that this is strange and probably a bad XML design however I need to create a serializable class to hold this information.

I can add an attribute to the tag to distinguish between them. Do you know how I can serialize this XML design (original post) into a class please?

The answer lies in how you defined your class!

.. you have "PlyrDetails" and "PlyrDetails2" - despite having the same xmelement name because they are different classes you will have 2 different elements in your xml document.

Do you need 2 different player details classes or can you not have one?

Can you post your code for your class please, just wanted to see how you've defined your class

Error reflecting type when trying to serialize

Hi, when I try and run this statement:

XmlSerializer

s = new XmlSerializer(typeof(PlayerXMLClass.Player));

The XML is unusual in its structure:

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<plyr xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">
 <club>Arsenal</club>
    <plyrdets>
       <first>Cesc</first>
       <last>Fab</last>
    </plyrdets>
    <plyrdets>
       <dob>12/12/1988</dob>
       <position>midfielder</position>
    </plyrdets>
</plyr>

The inner exception is:

The XML element 'plyrdets' from namespace is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.
