我已经申请了一个带有退出按钮的字幕文本。当禁用计时器时，该按钮可以正常工作，但是一旦启用计时器，则无法单击该按钮。 谁能帮帮我吗？我尝试过在线研究，但似乎没有答案，谢谢！ ：）
这是我拥有的代码

使用DispatchTimer，它将在单独的线程上运行，并且事件将在UI线程上触发，因此您将能够修改UI
private DispatcherTimer dispatcherTimer;
public FORM_ENTRY()
{
InitializeComponent();
LabelWelcome.Text = "Welcome! Welkom! Selamat Datang! Wilkommen!";
LabelCheckedIn.Visible = false;
LabelEnjoy.Visible = false;
// Initialize Dispatcher
dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
// Five seconds delay
dispatcherTimer.Interval = new TimeSpan(0, 0, 5);
dispatcherTimer.Start();
}
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder(LabelWelcome.Text);
char ch = sb[sb.Length - 1];
sb.Remove(sb.Length - 1, 1);
sb.Insert(0, ch);
LabelWelcome.Text = sb.ToString();
}
private void ButtonExit_Click(object sender, EventArgs e)
{
this.Close();
}
