//Enerweb Test

 

//Task 1

//Complete this program so that the list of companies can be loaded from a file and also saved to a file

//HINT: make use of XML serialization

//You may need to create the test xml data file by hand or any other mechanism

 

//Task 2

//Change the interface for the Company class so that the companies can be sorted by number of employees

//HINT: Use IComparable

 

//Task 3 - Advanced - if time available

//Create a generic Template Function for Loading any complex type from a file and saving any complex type to a file

 

using System;

using System.Collections.Generic;

using System.Text;

using System.Xml;

 

namespace EnerwebTest

{

      class Employee

      {

            string ID;

            string Name;

                  ShowCompanies(companies);

 

                  //TASK 2: by changing the interface of the Company class - the following

                  //line of code is all that is needed to sort the list

                  companies.Sort();

                  ShowCompanies(companies);

 

                  Save("companies.xml", companies);

 

 

                  //TASK 3 - the new generic overloaded Load/Save functions are used like this

            }
