Hi,
I've a class MyElement which represents a configuration element, so as .NET
2 it derives from ConfigurationElement.
I would like to create an instance of MyElement using a XML stream I loaded
from an external source (which is not a configuration file).

I tryed to use XmlSerializer like this :
XmlSerializer mySerializer = new XmlSerializer( typeof(
Settings.MyElement ) );
StreamWriter myWriter = new StreamWriter( @"c:\MyElement.xml" );
mySerializer.Serialize( myWriter, myObjectOfTypeMyElement );
myWriter.Close();

But it won't work complaining about the public field
ConfigurationLockCollection from the ConfigurationElement class not being
serializable !!

{System.InvalidOperationException: There was an error reflecting type
'App.MyElement'. ---> System.InvalidOperationException: You must implement a
default accessor on System.Configuration.ConfigurationLockCollection because
it inherits from ICollection.
at System.Xml.Serialization.TypeScope.GetDefaultIndexer(Type type, String
memberInfo).
......

Do I have to implement my own IXmlSerializer on the class ? But will it
still work as a configuration element ? Any other mean to do that ?
What a bad idead to have to derive from a framewrok class for the
configuration !!!! Microsoft team should change that again in the next
version.

Ok I've implemented the ISerializable interface and it works with both Xml
serialization and Configuration element serialization.

Thanks Microsoft teams for helping us NOT programming 2 times the same thing
