        Else
            Console.WriteLine("Array does not contain negative number")
        End If
    End Sub
End Module

Output

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.

In the Main() function, we created an integer array that contains 7 elements. Here, we checked an array that contains a negative number or not using Any() extension method and print the appropriate message on the console screen.
