in c#, when i add item to listView1 there will be two images via command:

string imgName = ImageList1.Images.Keys[i].ToString();
item.ImageIndex = ImageList1.Images.IndexOfKey(imgName);
listView1.Items.Add(item);
listView1.Update();

PictureBox pic = new PictureBox();
...
listView1.Controls.Add(pic);

adding item to listView1 works fine but when removing item, the image is ok
added by listView1.Controls.Add statement is not deleted, I want to delete this image, how do you write the command? you see my delete code

PictureBox pic = (PictureBox)listView1.SelectedItems[0];
listView1.Controls.Remove(pic);
listView1.SelectedItems[0].Remove();

I tried running the code you sent me, all didn't work. I have debug variable item.Tag before and after running the code on variable item.Tag nothing changes, this command has no operation listView1.Controls.Remove(pic);

if (listView1.SelectedItems.Count > 0)
{
    ListViewItem selectedItem = listView1.SelectedItems[0];
    // Assuming you've stored the PictureBox control as the Tag of the ListViewItem
    PictureBox pic = (PictureBox)selectedItem.Tag; 

    listView1.Controls.Remove(pic);
    listView1.Items.Remove(selectedItem);
}

// Assuming the selected item is a ListViewItem
ListViewItem selectedItem = listView1.SelectedItems[0];

// Removing the associated picture box control
if (selectedItem.Tag is PictureBox pic)
{
    listView1.Controls.Remove(pic);
}

// Removing the selected item from the list view
selectedItem.Remove();
