Small bet

If the two value passed in is the value of a cell in a DataRow, compare the type before calling the method with the same type

Deep Copy Part code:

C # entity class serialization and deserialization one (XmlSerializer)

C # entity class serialization and deserialization two (DatacontractserializeR)
