C# | Get an ICollection containing the values in HybridDictionary
HybridDictionary.Values property is used to get an ICollection containing the values in the HybridDictionary.
Syntax:
public System.Collections.ICollection Values { get; }
Return Value: It returns an ICollection containing the values in the HybridDictionary.
Below programs illustrate the use of HybridDictionary.Values property:
Example 1:
// C# code to get an ICollection containing // the values in the HybridDictionary. using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a HybridDictionary named myDict HybridDictionary myDict = new HybridDictionary(); // Adding key/value pairs in myDict myDict.Add( "A" , "Apple" ); myDict.Add( "B" , "Banana" ); myDict.Add( "C" , "Cat" ); myDict.Add( "D" , "Dog" ); myDict.Add( "E" , "Elephant" ); myDict.Add( "F" , "Fish" ); // Creating a String arr named myArr String[] myArr = new String[myDict.Count]; // copying the Values in HybridDictionary // to a one-dimensional Array instance // at the specified index. myDict.Values.CopyTo(myArr, 0); // To get an ICollection containing // the Values in the HybridDictionary for ( int i = 0; i < myDict.Count; i++) Console.WriteLine(myArr[i]); } } |
Output:
Apple Banana Cat Dog Elephant Fish
Example 2:
// C# code to get an ICollection containing // the values in the HybridDictionary. using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a HybridDictionary named myDict HybridDictionary myDict = new HybridDictionary(); // Adding key/value pairs in myDict myDict.Add( "I" , "first" ); myDict.Add( "II" , "second" ); myDict.Add( "III" , "third" ); myDict.Add( "IV" , "fourth" ); myDict.Add( "V" , "fifth" ); // Creating a String arr named myArr String[] myArr = new String[myDict.Count]; // copying the Values in HybridDictionary // to a one-dimensional Array instance // at the specified index. myDict.Values.CopyTo(myArr, 0); // To get an ICollection containing // the Values in the HybridDictionary for ( int i = 0; i < myDict.Count; i++) Console.WriteLine(myArr[i]); } } |
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 HybridDictionary. Therefore, changes to the HybridDictionary continue to be reflected in the ICollection.
- Retrieving the value of this property is an O(1) operation.
