WinForms Clearing multiple Textboxes with one command

I have several textboxes in a form, and have a button which inserts all the values in a Database and I have to clear the content of all the textboxes and focus to the first one right after pressing the button.

Now I can easily do that using the Clear method of each of the textboxes but it takes 10-12 lines of code just for that. Can I do that in one go?

For Each control In form.Controls
    If TypeOf control Is TextBox Then
        CType(control, TextBox).Clear()
    End If
Next

From your container (e.g. the Form), iterate through the controls collection and test whether a child is a TextBox. If so, cast it and then clear out the text. In VB.NET here is some code:

    For Each c As Control In Me.Controls
        If TypeOf c Is TextBox Then
            DirectCast(c, TextBox).Text = ""
        End If
    Next

You also can make a recursive version of this so that if you have controls that might contain other controls, they are processed as well.
