dynamically changing picture box

i dynamically create several picture box, and EventHandler. when user click on pictureBox, the program should delete tрis item. (the item that the user selected)

i try do 

for (int i = 1; i <= sunduki; i++)
        {
            PictureBox PBObj = new PictureBox();
            PBObj.Location = new System.Drawing.Point(i * 100, 101);
            PBObj.Name = "pictureBox" + i.ToString();
            PBObj.Size = new System.Drawing.Size(108, 80);
            PBObj.TabIndex = i;
            PBObj.BackgroundImage = Image.FromFile(@"syndyk1.jpg");
            PBObj.BackgroundImageLayout = ImageLayout.Zoom;
            PBObj.Click += new System.EventHandler(pb_Click); 
            PB.Add(PBObj);
            Controls.Add(PB[PB.Count - 1]);}

and in pb_click

private void pb_Click(object sender, EventArgs e)
    { PB[this].Visible = false; }

but i have an error. (PB is the list with pictureBox)

The sender argument will be the object that has been clicked, in this case it is the PictureBox object.

private void pb_Click(object sender, EventArgs e)
{ 
   var pb = sender as PictureBox;
   if(pb != null)
   {
       pb.Visible = false;
   }
}

Note: This doesn't delete the picture box, but makes it not visible. Controls deletion is handled by the disposal of the form.
