使用timer3.Stop（）或timer3.Start（）方法

{
if (e.Item == sender)
{
if (e.IsSelected) timer3.Start();

使用timer3.Stop（）或timer3.Start（）方法

{
if (e.Item == sender)
{
if (e.IsSelected) timer3.Start();
else timer3.Stop();

}
使用timer3.Stop（）或timer3.Start（）方法
private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
{
if (e.Item == sender)
{
if (e.IsSelected) timer3.Start();

使用timer3.Stop（）或timer3.Start（）方法
private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
{
if (e.Item == sender)
{
if (e.IsSelected) timer3.Start();
else timer3.Stop();

}
而不是执行timer3.Enabled=true或timer3.Enabled=false
使用timer3.Start（）和定时器3.Stop（）
在滴答声事件中停止计时器
将起作用
private void Form1_Load(object sender, EventArgs e)
{
timer3.Start();
}
private void InactiveCheck()
