问题描述
限时送ChatGPT账号..我不知道如何做到这一点,我曾尝试弄乱计时器,但到目前为止无济于事.
I've no real idea how to do this and I have tried messing with a timer but to no avail so far.
那我想做什么?
我有一个空白的标签.当某个事件被触发时,我希望标签在 5 秒内显示竞争成功设置",然后我希望它恢复为空白.
I have a label that is blank. When a certain event is triggered I want the label to say "Competition successfully setup" for a period of 5 seconds after which I want it to return to being blank.
这真的可以做到吗??它可以?我玩过计时器,但似乎不太理想.
Surely this can be done?? Can it? I have played around with a timer but I seem to be well off the mark.
非常欢迎任何帮助.我的微弱尝试如下.
Any help would be most welcome. My feeble attempt is below.
private void UpdateLabel(object sender, EventArgs e)
{
var timer = new Timer()
{
Interval = 5000,
};
timer.Tick += (s, evt) =>
lblCompetitionSetupSuccess.Text = "Competition successfully setup";
timer.Start();
lblCompetitionSetupSuccess.Text = string.Empty;
}
推荐答案
换个方式试试:
private void button1_Click(object sender, EventArgs e)
{
label1.Text = "I will vanish in 5 sec";
var timer = new Timer();
timer.Interval = 5000;
timer.Tick += (o, args) => label1.Text = "";
timer.Start();
}
首先将标签设置为您希望它显示 5 秒的任何文本
First set the label to whatever text you want it to display for 5 sec
label1.Text = "I will vanish in 5 sec";
然后设置您的计时器,以便在计时器过去时它将删除文本
Then setup your timer so that on timer elapsed it will remove the text
var timer = new Timer();
timer.Interval = 5000;
timer.Tick += (o, args) => label1.Text = "";
timer.Start();
如果您希望计时器在第一个计时器结束后停止:
If you want the timer to stop after the first timer elapse:
timer.Tick += (o, args) =>
{
label1.Text = "";
timer.Enabled = false;
};
