SortedList<TKey, TValue>.IDictionary.Values Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets an ICollection containing the values in the IDictionary.

Namespace:   System.Collections.Generic
Assembly:  System (in System.dll)

ICollection IDictionary.Values { get; }

Property Value

Type: System.Collections.ICollection

An ICollection containing the values in the IDictionary.

The order of the values in the ICollection is the same as the order in the SortedList<TKey, TValue>.

Retrieving the value of this property is an O(1) operation.

The following code example shows how to use the IDictionary.Values property of the System.Collections.IDictionary interface with a SortedList<TKey, TValue>, to list the values in the sorted list. The example also shows how to enumerate the key/value pairs in the sorted list; note that the enumerator for the System.Collections.IDictionary interface returns DictionaryEntry objects rather than KeyValuePair<TKey, TValue> objects.

The code example is part of a larger example, including output, provided for the IDictionary.Add method.

public class Example
    public static void Main()
        // Create a new sorted list of strings, with string keys,
        // and access it using the IDictionary interface.
        IDictionary openWith = new SortedList<string, string>();

        // Add some elements to the sorted list. There are no 
        // duplicate keys, but some of the values are duplicates.
        // IDictionary.Add throws an exception if incorrect types
        // are supplied for key or value.
        openWith.Add("txt", "notepad.exe");
        openWith.Add("bmp", "paint.exe");
        openWith.Add("dib", "paint.exe");
        openWith.Add("rtf", "wordpad.exe");
// To get the values alone, use the Values property.
ICollection icoll = openWith.Values;

// The elements of the collection are strongly typed
// with the type that was specified for values,
// even though the ICollection interface is not strongly
// typed.
foreach( string s in icoll )
    Console.WriteLine("Value = {0}", s);
// When you use foreach to enumerate sorted list elements
// with the IDictionary interface, the elements are retrieved
// as DictionaryEntry objects instead of KeyValuePair objects.
foreach( DictionaryEntry de in openWith )
    Console.WriteLine("Key = {0}, Value = {1}", 
        de.Key, de.Value);
