c# - Adding a select all shortcut (Ctrl + A) to a .net listview?

Like the subject says I have a listview, and I wanted to add the Ctrl + A select all shortcut to it. My first problem is that I can't figure out how to programmatically select all items in a listview. It seems like it should be relatively easy, like ListView.SelectAll() or ListView.Items.SelectAll(), but that doesn't appear to be the case. My next problem is how to define the keyboard shortcut for the ListView. Do I do it in a KeyUp event, but then how would you check two presses at once? Or is it a property that you set?

Any help here would be great.

You could accomplish both with something like this:

private void listView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.A && e.Control)
    {
        listView1.MultiSelect = true;
        foreach (ListViewItem item in listView1.Items)
        {
            item.Selected = true;
        }
    }
}
