C# | Gets an ICollection containing the values in the Hashtable

C# | Gets an ICollection containing the keys in the Hashtable

Hashtable.Values Property is used to get an ICollection containing the values in the Hashtable.

Syntax:

public virtual System.Collections.ICollection Values { get; }

Return Value: This property returns an ICollection containing the values in the Hashtable.

Note:

The order of values in the ICollection is unspecified.
Retrieving the value of this property is an O(1) operation.

Below programs illustrate the use of above-discussed property:

Example 1:

// C# code to get an ICollection containing 
// the values in the Hashtable. 
using System; 
using System.Collections; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Creating a Hashtable 
        Hashtable myTable = new Hashtable(); 
  
        // Adding elements in Hashtable 
        myTable.Add("g", "Beginner"); 
        myTable.Add("c", "c++"); 
        myTable.Add("d", "data structures"); 
        myTable.Add("q", "quiz"); 
  
        // Get a collection of the values 
        ICollection c = myTable.Values; 
  
        // Displaying the contents 
        foreach(string str in c) 
            Console.WriteLine(str + myTable[str]); 
    } 
} 

Output:

data structures
c++
quiz
Beginner

Example 2:

// C# code to get an ICollection containing 
// the values in the Hashtable. 
using System; 
using System.Collections; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Creating a Hashtable 
        Hashtable myTable = new Hashtable(); 
  
        // Adding elements in Hashtable 
        myTable.Add("India", "Country"); 
        myTable.Add("Chandigarh", "City"); 
        myTable.Add("Mars", "Planet"); 
        myTable.Add("China", "Country"); 
  
        // Get a collection of the values 
        ICollection c = myTable.Values; 
  
        // Displaying the contents 
        foreach(string str in c) 
            Console.WriteLine(str + myTable[str]); 
    } 
} 

Output:

City
Country
Country
Planet
