Dim nums() As Integer = {5, 7, 2, 3} // create array of integer with values 5,7,2,3

Dim numQuery = From num In nums // create a query and adds up the value of array which are greater then 4
Where num > 4 Select num

For Each num As Integer In numQuery // add the numQuery number to istOutput

lstOutput.Items.Add(num) Next

End Sub

last istOutput has { 5 , 7 }
