Here, we will use the Contains() method of the Queue collection class. This method returns a Boolean value, if the specified item exists in Queue collection then return "True" otherwise it returns "False".

Program/Source Code:

The source code to check the specified item exists in the Queue collection or not is given below. The given program is compiled and executed successfully.

'in the Queue collection or not.

Imports System
Imports System.Collections

Module Module1
    Sub Main()

        Dim queue As New Queue(5)

        queue.Enqueue("India")
        queue.Enqueue("USA")
        queue.Enqueue("UK")
        queue.Enqueue("CHINA")

        If (queue.Contains("India")) Then
            Console.WriteLine("Item exists in queue")
        Else
            Console.WriteLine("Item does not exist in queue")
        End If
    End Sub
End Module

Output:

Item exists in queue
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program, And, we created an object of the Queue collection class for 5 elements. After that, we inserted 4 items using the Enqueue() method and then check the item "India" exists in the Queue collection using Contains() method then print the "Item exists in queue" message on the console screen.
