Module Module1
    Sub Main()
        Dim intVals() As Integer = {50, 20, 40, -35, 10, 27, 60}

        Dim neg = intVals.Any(Function(val As Integer)
                                  Return val < 0
                              End Function)

        If neg = True Then
            Console.WriteLine("Array contains negative number")
        Else
            Console.WriteLine("Array does not contain negative number")
        End If
    End Sub
End Module

Output:

Array contains negative number
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.

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.
