C# Timer.GetHashCode方法代码示例

		internal override void SetTimer (Timer timer)
		{
			IntPtr	FosterParent=GetFosterParent();
			int	index;

			index = timer.GetHashCode();

			lock (timer_list) {
				timer_list[index]=timer;

			if (Win32SetTimer(FosterParent, index, (uint)timer.Interval, IntPtr.Zero) != IntPtr.Zero)
				timer.window = FosterParent;
			else
				timer.window = IntPtr.Zero;
		}

		internal override void KillTimer (Timer timer)
		{
			int	index;

			index = timer.GetHashCode();

			Win32KillTimer(timer.window, index);

			lock (timer_list) {
				timer_list.Remove(index);
			}

 /// <summary>
 /// Takes a time-out value which indicates that redraw shall not occur until: (a) the 
 /// corresponding unsuspendRedraw(suspend_handle_id) call has been made, (b) an 
 /// unsuspendRedrawAll() call has been made, or (c) its timer has timed out. In 
 /// environments that do not support interactivity (e.g., print media), then redraw shall 
 /// not be suspended. suspend_handle_id = suspendRedraw(max_wait_milliseconds) and 
 /// unsuspendRedraw(suspend_handle_id) must be packaged as balanced pairs. When you 
 /// want to suspend redraw actions as a collection of SVG DOM changes occur, then 
 /// precede the changes to the SVG DOM with a method call similar to 
 /// suspend_handle_id = suspendRedraw(max_wait_milliseconds) and follow the changes with 
 /// a method call similar to unsuspendRedraw(suspend_handle_id). Note that multiple 
 /// suspendRedraw calls can be used at once and that each such method call is treated
 /// independently of the other suspendRedraw method calls.
 /// </summary>
 /// <param name="max_wait_milliseconds">The amount of time in milliseconds to hold off

 /// down to 60 seconds.</param>
 /// <returns>A number which acts as a unique identifier for the given suspendRedraw() call. This value must be passed as the parameter to the corresponding unsuspendRedraw() method call.</returns>
