c# Array Part 2 (Using reference types)

Submitted by jin29neci on Sunday, August 29, 2010 - 21:24.
Using arrays in c#, you can also declare arrays of custom types. In our example let’s start with a Customer class, having two constructors, 3 properties (FirstName, LastName, ContactNumber), and an override of ToString() method of the Object class.
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5.  
  6. namespace ArraysPart2cs
  7. {
  8.     class Customer
  9.     {
  10.         #region -[Private Member Fields]-
  11.  
  12.         private string FirstName_;
  13.         private string LastName_;
  14.         private string ContactNumber_;
  15.  
  16.         #endregion
  17.  
  18.         //our first constructor
  19.         public Customer()
  20.         {
  21.          
  22.         }
  23.         //our second constructor
  24.         public Customer(string _FirstName, string _LastName, string _ContactNumber)
  25.         {
  26.             this.FirstName_ = _FirstName;
  27.             this.LastName_ = _LastName;
  28.             this.ContactNumber_ = _ContactNumber;
  29.         }
  30.  
  31.         #region -[Properties]-
  32.  
  33.         public string FirstName
  34.         {
  35.             get { return this.FirstName_; }
  36.             set { this.FirstName_ = value; }
  37.         }
  38.  
  39.         public string LastName
  40.         {
  41.             get { return this.LastName_; }
  42.             set { this.LastName_ = value; }
  43.         }
  44.  
  45.         public string ContactNumber
  46.         {
  47.             get { return this.ContactNumber_; }
  48.             set { this.ContactNumber_ = value; }
  49.         }
  50.  
  51.         #endregion
  52.        
  53.         public override string ToString()
  54.         {
  55.             string FullName = string.Concat(this.LastName_, " ", this.FirstName_);
  56.  
  57.             return string.Format("You are : {0}, your contact number: {1}", FullName, this.ContactNumber_);
  58.  
  59.         }
  60.     }
  61. }
Inside our main method, let’s try to use our custom type with arrays.
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5.  
  6. namespace ArraysPart2cs
  7. {
  8.     class Program
  9.     {
  10.         static void Main(string[] args)
  11.         {
  12.  
  13.             Console.Title = "Arrays Part 2";
  14.  
  15.            //so lets declare an array of customer having 2 elements
  16.  
  17.             Customer[] customer = new Customer[2];
  18.  
  19.             //lets try a short method
  20.  
  21.             customer[0] = new Customer("John Felix", "Cruz", "+639083069011");
  22.  
  23.             Console.WriteLine(customer[0].ToString());
  24.  
  25.             //lets try a long method
  26.  
  27.             customer[1] = new Customer();
  28.  
  29.             customer[1].FirstName = "Jin";
  30.             customer[1].LastName = "Zalzos";
  31.             customer[1].ContactNumber = "+639083069011";
  32.  
  33.             Console.WriteLine(customer[1].ToString());
  34.  
  35.      
  36.             //you may also use array initializer with custom types
  37.  
  38.             Customer[] anotherCustomer = {new Customer("Rhian","Calzado","+63908306911"),
  39.                                           new Customer("B. Togie", "Calzado", "+6301233655")};
  40.  
  41.             Console.WriteLine(anotherCustomer[0]);
  42.  
  43.             Console.ReadKey();
  44.  
  45.         }
  46.     }
  47. }
