我的问题是计时器标签无法显示剩余时间

推荐答案

使用Threading名称空间中的Timer类.在此处检查更多信息: http://msdn.microsoft.com/en-us/library/2x96zfy7.aspx

use Timer class from a Threading namespace. Check for more info here: http://msdn.microsoft.com/en-us/library/2x96zfy7.aspx

要记住:看一下这个例子:

To remember: take a look at this example:

Timer stateTimer = new Timer(Yout method, autoEvent, 1000, 250);

1.参数是您要调用的方法(计时器触发时将执行的代码)；

1. argument is the method you want to call (the code that will be executed when timer will trigger);

2.包含要由回调方法使用的信息的对象，如果您没有将其设置为 空.

2. object containing information to be used by the callback method, if you dont have any set it to null.

3.计时器第一次触发时的时间(以毫秒为单位)(如果在应用程序运行时从0开始执行).

3. the amount of time (in ms), when timer will tirgger for the 1st time (if 0 will start executing when application runs).

3.两次调用之间的时间(以毫秒为单位)(如果设置为3600000(3,6M)，它将每小时增加一次).

3. the amout of time (in ms), between invocations (if set to 3600000 (3,6M) it will rise every hour).
