Answer 1

Generic dictionaries cannot be XmlSerialized. The error you get is caused by the public property DicCtrl.

• Use the [XmlIgnore] attribute to skip this property when serializing (which is probably not what you want).
• Change the type of the property to a type that can be serialized e.g. List
• Find or implement a serializable dictionary
• Or implement IXmlSerializable

BTW the [Serializable] attribute is only needed for binary serialization. You do not need it for Xml serialization.
