- ## Examples   The following example uses the <xref:System.Runtime.Serialization.ISerializable.GetObjectData%2A> method to set alternate values for a serialized object. The code uses the <xref:System.Runtime.Serialization.SerializationInfo.AddValue%2A> method of the <xref:System.Runtime.Serialization.SerializationInfo> class to store the alternate values when the object is serialized. Conversely, when the constructor of the `Person` class is called during deserialization, the alternatve values are retrieved using the <xref:System.Runtime.Serialization.SerializationInfo.GetValue%2A> method and reassigned to the object's fields.
