How to pass the elements into list template

OK, I've used this sample xml file:


 
    bdnf
   
     
         1
         abc
         1000
     
     
         2
         def
         2000
     
   
 
 
    acme
   
     
         1
         ghi
         1500
     
     
         2
         jkl
         3000
     
     
         3
         mno
         4500
     
   
 


Here's the code:

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.Xml.Serialization;
using System.IO;


namespace DakeTest 
{ 
   public class Employee 
   { 
      public string ID {get; set;} 
      public string Name {get; set;} 
      public decimal Salary {get; set;} 
   }




   public class Company: IComparable
   {  
      public string Name {get; set;}
      public List Employees = new List();
      public Company()
      {
      } 


      public Company(string aName) 
      { 
         Name = aName; 
      } 


      public override string ToString() 
      { 
         return string.Format("Company {0}: Employees {1}", Name, Employees.Count); 
      } 


      public int CompareTo(Company other)
      {
        // If other.Name is null, this instance is greater.
        if (other.Name == null) return 1;


        // Otherwise, compare the Names of this and the other instance
        return this.Name.CompareTo(other.Name);
      }


   } 


  class Program 
  { 
      static XmlSerializer xs;
      static void Main(string[] args) 
      { 
         XmlRootAttribute root = new XmlRootAttribute();
         root.ElementName = "Companies";
         root.Namespace = "";
         root.IsNullable = false; 


         xs = new XmlSerializer(typeof(List), root);


         List companies = Load("companies.xml");
   
         ShowCompanies(companies);


         // now sort the Companies by Name and redisplay
         companies.Sort(); 
         ShowCompanies(companies); 
         Save("companies.xml", companies); 


         companies = Load>("companies.xml"); 
         ShowCompanies(companies);    
         Save>("companies.xml", companies); 
      } 
     
    private static List Load(string FileName) 
    { 
      List companies;


      using(Stream s = File.OpenRead(FileName))
      { 
        companies = (List)xs.Deserialize(s);
      }


      return companies; 
    } 
   
   
    private static void Save(string FileName, List companies) 
    { 
       using(Stream s = File.OpenWrite(FileName))
       {
          xs.Serialize(s, companies); 
       }
    }


    private static T Load(string FileName) 
    { 
       T objects;
       using(Stream s = File.OpenRead(FileName))
       { 
         objects = (T)xs.Deserialize(s);
       }


       return objects; 
    } 


    private static void Save(string FileName, T t) 
    { 
       using(Stream s = File.OpenWrite(FileName))
       {
          xs.Serialize(s, t); 
       }
    } 
   
    private static void ShowCompanies(List companies) 
    { 
       Console.WriteLine("List of companies:\n\n");


       foreach (Company company in companies) 
       { 
          Console.WriteLine(company); 
       } 


       Console.WriteLine("Done:\n\n\n"); 
    } 
  } 
}

hi frnd thanks for reply but i want code like this //Dake 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; namespace DakeTest { //Task 1 - Complete this class, members and its attributes for XML serialization class Employee { string ID; string Name; decimal Salary; } //Task 1 - Complete this class, members and attributes for XML serialization class Company { string Name; List employees = new List(); public Company(string aName) { Name = aName; } public override string ToString() { return string.Format("Company {0}: Employees {1}", Name, employees.Count); } } class Program { static void Main(string[] args) { List companies = Load("companies.xml"); 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 companies = Load>("companies.xml"); ShowCompanies(companies); Save>("companies.xml", companies); } //TASK 1 - complete this private static List Load(string FileName) { //TODO: complete this return null; } //TASK 1 - complete this private static void Save(string FileName, List companies) { //TODO: complete this } //TASK 3 - advanced - complete this private static T Load(string FileName) { //TODO: complete this return default(T); } //TASK 3 - advanced - complete this private static void Save(string FileName, T t) { //TODO: complete this } private static void ShowCompanies(List companies) { System.Console.WriteLine("List of companies:\n\n"); foreach (Company company in companies) { System.Console.WriteLine(company.ToString()); } System.Console.WriteLine("Done:\n\n\n"); } } }

thanks vulpes for giving nice suggestion
