C#: determining type of control

i'm a new to this thing, so please be gentle. and thanks in advance.. hehe... how do i do this? let's say i have controls in the group box and i want to determine whether the control is a textbox or not... if so, clear it....

psuedo code...

- foreach(control c in groupbox.controls)
- if c is textbox, c.text=string.empty

thanx again...

hello there... hehe... the answer is just the "is" word...

One line dude:

foreach (var c in panel.Controls.OfType<TextBox>()) c.Text = string.Empty;

Simply use riveting and rivetingly simple! Method.It even works from Control Arrays and can be called from events other than GotFocus such as Change and Keydown...
