C# | Dictionary.Values Property
This property is used to get a collection containing the values in the Dictionary<TKey,TValue>.
Syntax:
public System.Collections.Generic.Dictionary<TKey, TValue>.KeyCollection Values{ get; }
Return Value: This property returns a collection containing the Values in the Dictionary.
Below are the programs to illustrate the use of Dictionary<TKey,TValue>.Values Property:
Example 1:
// C# code to get the Values // in the Dictionary using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Create a new dictionary // of strings, with string keys. Dictionary< string , string > myDict = new Dictionary< string , string >(); // Adding key/value pairs in myDict 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" ); // To get count of key/value pairs in myDict Console.WriteLine( "Total key/value pairs" + " in myDict are : " + myDict.Count); // To get the values alone, // use the Values property. Dictionary< string , string >.ValueCollection valueColl = myDict.Values; // The elements of the ValueCollection // are strongly typed with the type // that was specified for dictionary values. foreach ( string s in valueColl) { Console.WriteLine( "Value = {0}" , s); } } } |
Output:
Total key/value pairs in myDict are : 6 Value = Canberra Value = Brussels Value = Amsterdam Value = Beijing Value = Moscow Value = New Delhi
Example 2:
// C# code to get the values // in the Dictionary using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Create a new dictionary of // strings, with string keys. Dictionary< int , int > myDict = new Dictionary< int , int >(); // Adding key/value pairs in myDict myDict.Add(9, 8); myDict.Add(3, 4); myDict.Add(4, 7); myDict.Add(1, 7); // To get count of key/value pairs in myDict Console.WriteLine( "Total key/value pairs " + "in myDict are : " + myDict.Count); // To get the values alone, // use the Values property. Dictionary< int , int >.ValueCollection valueColl = myDict.Values; // The elements of the ValueCollection // are strongly typed with the type // that was specified for dictionary values. foreach ( int s in valueColl) { Console.WriteLine( "Values = {0}" , s); } } } |
Output:
Total key/value pairs in myDict are : 4 Values = 8 Values = 4 Values = 7 Values = 7
