Question

C# ListBox怎么使用"Delete"删除里面的内容？？

我给ListBox绑了一个KeyPress事件，写法如下，没反映？？？
private void listBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (listBox1.Items.Count == 0)
{
return;
}
if (e.KeyChar == (Char)Keys.Delete)
{
listBox1.Items.RemoveAt(listBox1.SelectedIndex);
}
}

Answer 1

private void listBox1_KeyUp(object sender, KeyEventArgs e){
if(e.KeyCode==Keys.Delete)MessageBox.Show("DEL");
}

响应keyup事件
