[RESOLVED] [3.0/LINQ] Foreach (Picturebox pbx...?

Hello!

I have 9 pictureboxes in a window's form.
I wish to set the image of all of these to one that I specify.

How can I do this with a foreach-loop, or is there any other way?

I tried to use:

Code:

---

  foreach (PictureBox pbx in this)
            {
                pbx.Image = imgBoard;
            }

---

but it doesn't work.

Thanks for any help at all!

you loop through the control container not the form itself

Thanks for a quick answer!
Just found the control container, and I get no compile error but the application crashes just as it starts.

Any thoughts?

Code:

---

foreach (Control c in this.Controls)
{
  if (c is PictureBox)
  {
    // do code
  }
}

Yeah, use this.Controls.
This wont work though:

C# Code:

foreach(PictureBox p in this.Controls)
{
}

Because it will visit every control in the form container and implicitly try to cast them to Pictureboxes, upon reaching a control that isnt a PictureBox, an exception will occur. You'd have to do:

C# Code:

foreach(Control c in this.Controls)
{
    if(c is PictureBox)
        ((PictureBox)c).Image = Something
}

To get around that hassle, it's easier to use an array of PictureBoxes. Its much more effective, as you wont have to loop through every control to find the pictureboxes.

Edit: Oh my, shouldve refreshed before posting.

Aha!

Thank you both for answering, specially Atheist for giving detailed information as well! Greatly appreciated! (:
