在我的c#app中,我试图更改按钮的背景图像并在几秒钟后将其更改回来。但是,直到计时器启动后才会更改背景图像,然后在您看到更改之前立即将其更改回原始图像。
private void button1_Click(object sender, EventArgs e)
{
myImage.BackgroundImage = Properties.Resources.newImage;
System.Threading.Thread.Sleep(5000);
myImage.BackgroundImage = Properties.Resources.myImage;
}
答案 0 :(得分:1)
假设这是一个WPF应用,请添加DispatcherTimer
,如以下代码段所示:
DispatcherTimer _dispatcherTimer = new DispatcherTimer();
public MainWindow()
{
InitializeComponent();
button1.Click += button1_Click;
_dispatcherTimer.Tick += new EventHandler(dt_Tick);
_dispatcherTimer.Interval = new TimeSpan(0, 0, 0, 5);
}
private void button1_Click(object sender, RoutedEventArgs e)
{
myImage.BackgroundImage = Properties.Resources.newImage;
_dispatcherTimer.Start();
}
void dt_Tick(object sender, EventArgs e)
{
_dispatcherTimer.Stop();
myImage.BackgroundImage = Properties.Resources.myImage;
}
希望这会有所帮助。
