Question

I am initializing an array of PictureBox. The matter is, I cannot add individual EventHandler with each. I have this code in a for loop:

picBoxs[i] = new PictureBox();
picBoxs[i].Anchor = AnchorStyles.None;
picBoxs[i].Location = new Point(x, y);
picBoxs[i].Size = new Size(104, 104);
picBoxs[i].SizeMode = PictureBoxSizeMode.Normal;
picBoxs[i].BorderStyle = BorderStyle.FixedSingle;
//this.picBoxs[i].Click += new System.EventHandler(this.picBoxs_Click); //Single EventHandler for all PictureBox(s)
this.picBoxs[i].Click += new System.EventHandler(this.picBoxs[i]_Click); //Generates error

I want picBoxs1_Click(), picBoxs2_Click(), picBoxs3_Click() …(and so on). Because I need EventHandler for each PictureBox. I can make general EventHandler, picBox_Click() without any problem, but doing this I get a method for every PictureBox, I cannot do different stuffs after clicking different PictureBox. Any idea will greatly be appreciated.

Thanks in advance…

Edit:
I want, when I click on a PictureBox, a message box will appear telling me an index of a 2D array. Say my picturebox(s) are arranged like this:

picBox0 picBox1 picBox2

picBox3 picBox4 picBox5

after clicking picBox2: MessageBox will say “[0][2]”, same as clicking picBox4: MessageBox will say “[1][1]” and so on…

Use a single event handler, like this:

this.picBoxs[i].Click += picBoxs_Click;

And within that event handler you can look up information about your picturebox:

void picBoxs_Click(object sender, EventArgs e)
{
    var box = sender as PictureBox;
    int i = Array.IndexOf(picBoxs, box);

    int columnCount = 3;
    int row = i / columnCount;
    int col = i % columnCount;

    Messagebox.Show(string.Format("[{0}][{1}]", row, col));       
}
