C# 中的 PictureBox 值

Question

I have a question I'm still a newbie in C#. I have 10 pictureBox in my Form and in a method that I've created I need to change the picture but the pictureBox can change like this:

void evaluate(int c, int i) {
if (contador == 2)
{
    if (aux == i + 10 || aux + 10 == i)
    {
    }
    else 
    { 
        pictureBox+aux+.Image.FromFile(@"C:\MyGame Directory\new.jpg"); 
    }
}

I need something like this: Concatenate the pictureBox+myVariable+

Answer 1

Try an array of PictureBox variables (assuming aux is an int). Then reference one with array notation:

pictureBoxes[aux].Image.FromFile(@"...");

Answer 2

Put all your pictureBox controls in a dictionary with aux as the key, assuming aux is a int:

Dictionary<int,PictureBox> picBoxes = new Dictionary<int,PictureBox>();

picBoxes[aux].Image.FromFile(@"C:\MyGame Directory\new.jpg");

Answer 3

I think you should use an array of PictureBox controls and then set the value for each of the contents using an index.

This may help:

Answer 4

Is it necessary to have soo many picture boxes? Instead have 1 and rotate the pics in it based on a timer or some logic.
