C# | Get an ICollection containing the values in ListDictionary

Last Updated : 01 Feb, 2019

ListDictionary.Values property is used to get an ICollection containing the values in the ListDictionary. Syntax:

public System.Collections.ICollection Values { get; }

Return Value : It returns an ICollection containing the values in the ListDictionary. Below are the programs to illustrate the use of ListDictionary.Values property: Example 1:

CSHARP

// C# code to get an ICollection
// containing the values in the ListDictionary
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a ListDictionary named myDict
        ListDictionary myDict = new ListDictionary();

        myDict.Add("Australia", "Canberra");
        myDict.Add("Belgium", "Brussels");
        myDict.Add("Netherlands", "Amsterdam");
        myDict.Add("China", "Beijing");
        myDict.Add("Russia", "Moscow");
        myDict.Add("India", "New Delhi");

        // Get an ICollection containing
        // the values in the ListDictionary
        ICollection ic = myDict.Values;

        // Displaying the values in ICollection ic
        foreach(String str in ic)
        {
            Console.WriteLine(str);
        }
    }
}

Output:

Canberra
Brussels
Amsterdam
Beijing
Moscow
New Delhi

Example 2 :

CSHARP

// C# code to get an ICollection
// containing the values in the ListDictionary
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a ListDictionary named myDict
        ListDictionary myDict = new ListDictionary();

        myDict.Add("I", "first");
        myDict.Add("II", "second");
        myDict.Add("III", "third");
        myDict.Add("IV", "fourth");
        myDict.Add("V", "fifth");

        // Get an ICollection containing
        // the values in the ListDictionary
        ICollection ic = myDict.Values;

        // Displaying the values in ICollection ic
        foreach(String str in ic)
        {
            Console.WriteLine(str);
        }
    }
}

Output:

first
second
third
fourth
fifth

Note:

The order of the values in the ICollection is unspecified, but it is the same order as the associated keys in the ICollection returned by the Keys method.
The returned ICollection is not a static copy. Instead, the ICollection refers back to the values in the original ListDictionary. Therefore, changes to the ListDictionary continue to be reflected in the ICollection.
Retrieving the value of this property is an O(1) operation.
