As you know, array indexing is performed using the [ ] operator It is possible to define the [ ] operator for classes that you create, but you don t use an operator method Instead, you create an indexer An indexer allows an object to be indexed like an array The main use of indexers is to support the creation of specialized arrays that are subject to one or more constraints However, you can use an indexer for any purpose for which an array-like syntax is beneficial Indexers can have one or more dimensions We will begin with onedimensional indexers

Note: We will also use the Rename item in this menu later in the chapter to rename the Form1.cs file. 2 Select the View Code item. A Form1.cs tab appears in the main window containing the C# code for your application.

A one-dimensional indexer has this general form: element-type this[int index] { // The get accessor get { // return the value speci ed by index } // The set accessor set { // set the value speci ed by index } }

Part I:

using using using using using using System; System.Drawing; System.Collections; System.ComponentModel; System.Windows.Forms; System.Data;

.

namespace MyPhotos { /// <summary> XML documentation /// Summary description for Form1. /// </summary> public class Form1 : System.Windows.Forms.Form { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null;

Here, element-type is the element type of the indexer Thus, each element accessed by the indexer will be of type element-type This type corresponds to the element type of an array The parameter index receives the index of the element being accessed Technically, this parameter does not have to be of type int, but since indexers are typically used to provide array indexing, an integer type is customary Inside the body of the indexer two accessors are defined that are called get and set An accessor is similar to a method except that it does not declare a return type or parameters The accessors are automatically called when the indexer is used, and both accessors receive index as a parameter If the indexer is on the left side of an assignment statement, then the set accessor is called and the element specified by index must be set Otherwise, the get accessor is called and the value associated with index must be returned The set method also receives an implicit parameter called value, which contains the value being assigned to the specified index One of the benefits of an indexer is that you can control precisely how an array is accessed, heading off improper access Here is an example In the following program, the FailSoftArray class implements an array that traps boundary errors, thus preventing runtime exceptions if the array is indexed out-of-bounds This is accomplished by encapsulating the array as a private member of a class, allowing access to the array only through the indexer With this approach, any attempt to access the array beyond its boundaries can be prevented, with such an attempt failing gracefully (resulting in a soft landing rather than a crash ) Since FailSoftArray uses an indexer, the array can be accessed using the normal array notation.

// Use an indexer to create a fail-soft array using System; class FailSoftArray { int[] a; // reference to underlying array public int Length; // Length is public public bool ErrFlag; // indicates outcome of last operation // Construct array given its size public FailSoftArray(int size) { a = new int[size]; Length = size; } // This is the indexer for FailSoftArray public int this[int index] { // This is the get accessor get { if(ok(index)) { ErrFlag = false; return a[index]; } else { ErrFlag = true; return 0; } }

public Form1() {

10:

// // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); }
