To make the object to serialize in your own way better to implement ISerializableinside the class, specifying the members whose data need to be serialize inside method GetObjectData (a ISerializable member method) , parameter ofSerializationInfo will hold the key value pair kind of information to allow the Serialization.
Also class needs to have constructor having same signature of GetObjectData, so that at the time of de-serializing the serialized data will be passed via parameter of the constructor, as data are already added in Key Value pare kind of form in GetObjectData its easy to get restore the state to its member.
To illustrate the usage in application, the base class is used to make the member serialize
