C#: Searching through arrays
- by Jonathan Oberhaus
I have a dvd app that stores dvds and blu-rays, I want to search the arrays by director. Below is the code for the inventory class I have seen many different ways to do this. There seems to be some debate as the best/most efficient way to accomplish this, any suggestions?
Blockquote
namespace MovieInventoryApplication
{
class Inventory
{
public Bluray[] BlurayMovies;
public DVD[] DVDMovies;
private int blurayCount;
private int dvdCount;
public Inventory()
{
BlurayMovies = new Bluray[5];
DVDMovies = new DVD[5];
blurayCount = 0;
dvdCount = 0;
}
public void AddBluray()
{
String strTitle;
int intReleaseYear;
int intRunningTimeMinutes;
String strDirector;
int intPrice;
int intRegionCode;
try
{
Console.Write("Enter a title: ");
strTitle = Console.ReadLine();
Console.Write("Enter a release year: ");
intReleaseYear = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter the running time in minutes: ");
intRunningTimeMinutes = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter the directors name: ");
strDirector = Console.ReadLine();
Console.Write("Enter a rental price: ");
intPrice = Convert.ToInt32(Console.ReadLine());
BlurayMovies[blurayCount] = new Bluray(strTitle, intReleaseYear, intRunningTimeMinutes, strDirector, intPrice);
blurayCount++;
Console.Write("Enter the DVD region code: ");
intRegionCode = Convert.ToInt32(Console.ReadLine());
DVDMovies[dvdCount] = new DVD(strTitle, intReleaseYear, intRunningTimeMinutes, strDirector, intPrice, intRegionCode);
dvdCount++;
}
catch (FormatException FormatException)
{
Console.WriteLine(FormatException.Message);
Console.WriteLine("Please enter a number in this field.");
}

public void ListAllBluray()
{
int position = 0;
while (BlurayMovies[position] != null)
{
Console.WriteLine(position + " " + BlurayMovies[position].strTitle);
position++;
}
}
public void ListAllDVD()
{
int position = 0;
while (DVDMovies[position] != null)
{
//position + 1 + " " +
Console.WriteLine(position + " " + DVDMovies[position].strTitle);
position++;
}
}
public void BlurayInfo(int position)
{
Console.WriteLine("Title: {0}", DVDMovies[position].strTitle);
Console.WriteLine("Release Year: {0}", DVDMovies[position].intReleaseYear);
