C# | Get a collection of values in the StringDictionary
StringDictionary.Values property is used to get a collection of values in the StringDictionary.
Syntax:
public virtual System.Collections.ICollection Values { get; }
Return Value: An ICollection that provides the values in the StringDictionary.
Example 1:
// C# code to get a collection // of values in the StringDictionary using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a StringDictionary named myDict StringDictionary myDict = new StringDictionary(); // Adding key and value into the StringDictionary myDict.Add( "A" , "Apple" ); myDict.Add( "B" , "Banana" ); myDict.Add( "C" , "Cat" ); myDict.Add( "D" , "Dog" ); // Getting a collection of values // in the StringDictionary foreach ( string val in myDict.Values) { Console.WriteLine(val); } } } |
Output:
Dog Banana Cat Apple
Example 2:
// C# code to get a collection // of values in the StringDictionary using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a StringDictionary named myDict StringDictionary myDict = new StringDictionary(); // Adding key and value into the StringDictionary myDict.Add( "3" , "prime & odd" ); myDict.Add( "2" , "prime & even" ); myDict.Add( "4" , "non-prime & even" ); myDict.Add( "9" , "non-prime & odd" ); // Getting a collection of values // in the StringDictionary foreach ( string val in myDict.Values) { Console.WriteLine(val); } } } |
Output:
prime & even prime & odd non-prime & odd non-prime & even
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 StringDictionary. Therefore, changes to the StringDictionary continue to be reflected in the ICollection.
- Retrieving the value of this property is an O(1) operation.
