Looping though elements in vb.net

问题

Is there a way I can loop though multiple elements with number based names, changing their properties?

Example:

Here are an example set of elements on my form:

Element1
Element2
Element3
Element4
Element5

This is the kind of thing i was thinking of:

For i = 1 To 5
    Element + i .BackColor = Color.Maroon 
Next

This is just because I have a large number of elements, which i would like to change the properties of during the application running.

Thanks for any answers.

Sure, replace Me.Controls with another control collection if that is not the right one.

Label example:

For i = 1 To 5
  Dim lb = TryCast(GameInterface.Controls("Element" & i.ToString), Label)
  If lb IsNot Nothing Then lb.BackColor = Color.Maroon 
Next

If it is for labels on form then try this: replace parent with Parent control

Private Sub SetControls()
        Dim xControl As Control
        For Each xControl parent.Controls
            If (TypeOf xControl Is Label ) Then
                xControl.backcolor= Color.Maroon
            End If
        Next xControl
End Sub
