Enerweb Test

//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
