Serialization and Deserialization using Json and XML The Atom class This is the front end of the application. There are 12 members.   Atom Class Fields   Properties + «c# property, set» Name            : string + «c# property, set» Symbol          : string + «c# property, set» Proton          : int + «c# property, set» Neutron         : int + «c# property, set» Weight          : double   Methods + «c# constructor» Atom() + «c# constructor» Atom(      string name,      int proton,      int neutron,      double weight,      string symbol) $+ Parse(string objectData)         : Atom $+ GetAtoms()                       : List + ToString()                        : double     Description of class members Fields: There are no fields in this class. Properties: All the properties have public get and set Name – this is a string representing the name of this atom. Both the getter and setter are public. Symbol – this is a two-letter string representing the name of this atom that is used in chemistry. Both the getter and setter are public. Proton – this is an int representing the number of protons in the nucleus of this atom. Both the getter and setter are public. Neutron – this is a int representing the number of neutrons in the nucleus of this atom. Both the getter and setter are public. Weight – this is a double representing the atomic weight of this atom. Both the getter and setter are public. Constructor: There are two constructors for this class: a default one and a user defined one public Atom() – This is a default constructor that is necessary for serialization. This is an empty constructor that does not do anything. public Atom(string name, int proton, int neutron, double weight, string symbol) – This constructor assigns the arguments to the appropriate fields. Methods public static Atom Parse(string line) – This is a public class method that takes a string and returns an Atom object. The argument is one string that is comprised of the five fields of this object. It does the following: It uses the Split() method to parse the argument into five parts. Create an Atom object and initialize the fields with the appropriate parts. Return the above object You will need to examine the arguments to decide what part will be assigned to which field. public override string ToString() – This is a public method overrides the corresponding method in the object class to return a string form of the object. Test Harness Insert the following code statements in your Program.cs file: Write or create Four methods that will be called from Main. The Write method will serialize a collection of atoms to a file and the Read method will deserialized the contents of a file to a list of atoms. static void WriteJson(List atoms, string filename) – This void class method that takes the list of atoms and a filename. You will write the necessary code to serialize the first argument to the specified file. static void ReadJson(string filename) – This void class method that takes a filename. You will write the necessary code to deserialize the file contents to a List and then display all atoms. static void WriteXML(List atoms, string filename) – This void class method that takes the list of atoms and a filename. You will write the necessary code to serialize the first argument to the specified file. static void ReadXML(string filename) – This void class method that takes a filename. You will write the necessary code to deserialize the file contents to a List and then display all atoms.   Appendix Code for the GetAtoms method of the Atom class
