How can I Copy to clipboard, a ListView's multiple selected items?

Question

This code is working for one single selected item: In the top:

ContextMenuStrip menuStrip;

Then in the constructor:

menuStrip = new ContextMenuStrip();
menuStrip.ItemClicked += menuStrip_ItemClicked;
menuStrip.Items.Add("Cut");
menuStrip.Items.Add("Copy");
menuStrip.Items.Add("Paste");

The menuStrip itemclicked event:

ListViewItem item;
        private void menuStrip_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
        {
            if (e.ClickedItem.Text == "Copy")
            {
                Clipboard.SetText(item.SubItems[1].Text);

            }
        }

Then the ListView mouse click event:

private void lstDisplayHardware_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                item = lstDisplayHardware.GetItemAt(e.X, e.Y);
                menuStrip.Show(lstDisplayHardware, e.Location);
            }
        }

This code is working for single selected item. For example I click on an item in the ListView, right click on the item and select Copy: the selected item's subitem is copied to the Clipboard.

But now I want to do the same thing for multiple selection.

So if I use Ctrl+Left mouse click and for example selected 4 items and invoke Copy command from the context menu, I expect all subitems of the 4 selected items text to be copied into the Clipboard.

For example I have these items:

danny hello world
daniel hi all
dan rain today
daniels sunny day

I select the items:

danny
daniel
dan
daniels

Then right click and click on Copy. When I paste anywhere from the clipboard I want it to show:

hello world
hi all
rain today
sunny day

All of the sub items of the selected items in the same order and format.

Answer 1

First, you have to enable multiselect:

ListView1.MultiSelect = true;

Then, you can get selected items with:

private void menuStrip_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
    ListView.SelectedListViewItemCollection selectedItems = 
    ListView1.SelectedItems;
    if (e.ClickedItem.Text == "Copy")
    {
         String text = "";
         foreach ( ListViewItem item in selectedItems )
         {
              text += item.SubItems[1].Text;
         }
         Clipboard.SetText(text);
    }
}

Answer 2

    private void listBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == Keys.C)
        {
            CopyListBox(listBox1);
        }
    }

    public void CopyListBox(ListBox list)
    {

        StringBuilder sb = new StringBuilder();
        foreach (string item in list.SelectedItems)
        {
            sb.AppendLine(item);
        }

        Clipboard.SetDataObject(sb.ToString());

    }
