解决方案

您可以在下面的代码中进行操作:

 ListView1.Items.RemoveAt(i)

u可以尝试此

(ListView1.ListItems.Remove (ListView1.SelectedItem.Index) )

好吧..那就试试这个吧..让我知道...

  1 )在表单上，​​只需拖动一个Listview.
 2 )在Listview '  s Items属性中，添加您的弦(放3弦
例如).
3)将Listview的MultiSelect属性设置为False.
 4 )在您的Listview ' 的KeyDown事件中，键入:

        私人无效listView1_KeyDown(对象发送者，KeyEventArgs e)
        {
            如果(e.KeyCode == Keys.Delete)
            {
                listView1.Items.Remove(listView1.FocusedItem);
            }
        }

5)运行程序.至少有个项目被选中.继续按
'  Del'(删除)键

解决方案

you can you below code:

ListView1.Items.RemoveAt(i)

u can try this

(ListView1.ListItems.Remove (ListView1.SelectedItem.Index) )

Ok..try this one then..and let me know...

1) On your form, just drag a Listview.
2) In the Listview's Items property, add your strings (put 3 strings
for example).
3) Set the Listview's MultiSelect property to False.
4) In your Listview's KeyDown event, type:

        private void listView1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Delete)
            {
                listView1.Items.Remove(listView1.FocusedItem);
            }
        }

5) Run the program. There's at least one item selected. Keep pressing
the 'Del' (Delete) key
