An ICollection containing the values in the IDictionary.

Implements

Values

Examples

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");

Public Class Example
    
    Public Shared Sub Main() 

        ' Create a new sorted list of strings, with string keys,
        ' and access it using the IDictionary interface.
        '
        Dim openWith As IDictionary = _
            New sortedList(Of 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.
Console.WriteLine();
foreach( string s in icoll )
{
    Console.WriteLine("Value = {0}", s);
}

' To get the values alone, use the Values property.
Dim icoll As ICollection = openWith.Values

' The elements of the collection are strongly typed
' with the type that was specified for sorted list values,
' even though the ICollection interface is not strongly
' typed.
Console.WriteLine()
For Each s As String In  icoll
    Console.WriteLine("Value = {0}", s)
Next 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.
Console.WriteLine();
foreach( DictionaryEntry de in openWith )
{
    Console.WriteLine("Key = {0}, Value = {1}",
        de.Key, de.Value);
}

' When you use foreach to enumerate sorted list elements
' with the IDictionary interface, the elements are retrieved
' as DictionaryEntry objects instead of KeyValuePair objects.
Console.WriteLine()
For Each de As DictionaryEntry In openWith
    Console.WriteLine("Key = {0}, Value = {1}", _
        de.Key, de.Value)
Next

    }
}


    End Sub

End Class

Remarks

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.
