C# Add image to pictureboxes with List

Question

First of all, sorry for my english.

I'm making a program that has about 60 pictureboxes. (pictureBox1, pictureBox2, pictureBox3, till pictureBox60)

And I have a list with 60 strings. (urls to different images)

I want for pictureBox1 to load the list[0], pictureBox2 to load the list[1], etc..

But i realized i can't make the following:

for (int i = 0; i < Bans.Count; i++)
{
    this.pictureBox + i = this.Bans[i]; //Can't be done.. 
}

Is there a solution that does not require me to manually set all 60 boxes?

Thanks!

Is this WPF or WinForms?

If this is WinForms, you can use ControlCollection.Find to get controls by name - assuming each of your pictureboxN controls has a matching .Name property value.

e.g.

pictureBox23.Name = "pictureBox23";

like so:

for( int i = 0; i < this.Bans.Count; i++ ) {

    String pictureBoxName = "pictureBox" + i.ToString(CultureInfo.InvariantCulture);
    Control[] matchingPictureBoxes = this.Controls.Find( pictureBoxName, searchAllChildren: true );
    if( matchingPictureBoxes.Length == 1 ) {
        PictureBox pictureBox = (PictureBox)controls[0];
        pictureBox.Image = this.Bans[i];
    }
}
