Iterate through visual objects

Question

I am having a problem in Visual Studio 2013. I have like 72 picture boxes. And I have a variable named code which takes a random number like 13. Now I want to change pictureBox 13 's background color. But I don't want to make a long switch case for it. I just want something like a

for(int i=0;i<73;i++)
    pictureBox + code.BackColor = Color.Brown;

Is this possible?

Answer 1

No loop needed (at least no loop written by you) but a single line could return the required box

string name = "pictureBox" + randomNumber.ToString();
PictureBox p = this.Controls.OfType<PictureBox>()
                            .FirstOrDefault(x => x.Name == name)
p.BackColor = yourColor;
