IList defines the following properties: bool IsFixedSize { get; } bool IsReadOnly { get; } If the collection is of fixed size, IsFixedSize is true This means elements cannot be inserted or removed If the collection is read-only, then IsReadOnly is true This means the contents of the collection cannot be changed IList defines the following indexer: object this[int index] { get; set; } You will use this indexer to get or set the value of an element However, you cannot use it to add a new element to the collection To add an element to a list, call Add( ) Once it is added, you can access the element through the indexer

The IDictionary interface defines the behavior of a non-generic collection that maps unique keys to values A key is an object that you use to retrieve a value at a later date Thus, a collection that implements IDictionary stores key/value pairs Once the pair is stored, you can retrieve it by using its key IDictionary inherits ICollection and IEnumerable The methods declared by IDictionary are summarized in Table 25-3 Several methods throw an ArgumentNullException if an attempt is made to specify a null key and null keys are not allowed To add a key/value pair to an IDictionary collection, use Add( ) Notice that the key and its value are specified separately To remove an element, specify the key of the object in a call to Remove( ) To empty the collection, call Clear( )

Exploring the C# Library
Method void Add(object key, object value) void Clear( ) bool Contains(object key) IDictionaryEnumerator GetEnumerator( ) void Remove(object key)
TABLE 25-3
Description Adds the key/value pair specified by key and value to the invoking collection Removes all key/value pairs from the invoking collection Returns true if the invoking collection contains key as a key Otherwise, returns false Returns the enumerator for the invoking collection Removes the entry whose key equals key
The Methods De ned by IDictionary
You can determine whether a collection contains a specific object by calling Contains( ) with the key of the desired item GetEnumerator( ) obtains an enumerator compatible with an IDictionary collection This enumerator operates on key/value pairs IDictionary defines the following properties:
Property bool IsFixedSize { get; } bool IsReadOnly { get; } ICollection Keys { get; } ICollection Values { get; } Description Is true if the dictionary is of fixed size Is true if the dictionary is read-only Obtains a collection of the keys Obtains a collection of the values
Notice that the keys and values contained within the collection are available as separate lists through the Keys and Values properties IDictionary defines the following indexer: object this[object key] { get; set; } You can use this indexer to get or set the value of an element You can also use it to add a new element to the collection Notice that the index is not actually an index, but rather the key of the item
