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

Last Updated : 11 Jul, 2025
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: CSharp
// 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", "geeks");
        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
geeks
Example 2: CSharp
// 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
