推荐答案

C#中存在三种不同的计时器类:

• System.Threading.Timer;
  请参见 http://msdn.microsoft.com /en-us/library/system.threading.timer.aspx [ ^ ];
• System.Timers.Timer;
  请参见http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx [ http://msdn.microsoft.com/en-us/library /system.windows.forms.timer.aspx [

There are three different timer classes in C#:

• System.Threading.Timer;
  see http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx[^];
• System.Timers.Timer;
  see http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx[^];
• System.Windows.Forms.Timer;
  see http://msdn.microsoft.com/en-us/library/system.windows.forms.timer.aspx[^].

1. 避免使用System.Windows.Forms.Timer;它使用起来最简单，但最不准确.其他两种类型需要使用System.Windows.Threading.Dispatcher的Invoke或BeginInvoke方法(对于Forms或WPF)或System.Windows.Forms.Control(仅对于Forms).
   参见:
   http://msdn.microsoft.com/en-us/library/system. windows.threading.dispatcher.aspx [ ^ ]，
   http://msdn.microsoft.com/en-us/library/system. windows.forms.control.aspx [ ^ ].
2. 请务必避免使用计时器；
3. 避免使用"{0}和{1}之间的区别是什么"形式的问题；它们不正确.

1. Avoid using System.Windows.Forms.Timer; it simplest to use but is the most inaccurate. The other two types require to use the method Invoke or BeginInvoke of System.Windows.Threading.Dispatcher (for both Forms or WPF) or System.Windows.Forms.Control (Forms only).
   See:
   http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatcher.aspx[^],
   http://msdn.microsoft.com/en-us/library/system.windows.forms.control.aspx[^].
2. Avoid using timers by all means; use threads whenever possible.
3. Avoid questions in the form "What''s the difference between {0} and {1}"; they cannot be correct.
