Timer Constructor (TimerCallback, Object, UInt32, UInt32)
Initializes a new instance of the Timer class, using 32-bit unsigned integers to measure time intervals.
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] public Timer( TimerCallback callback, object state, uint dueTime, uint period )
A delegate representing a method to be executed.
An object containing information to be used by the callback method, or null.
The amount of time to delay before callback is invoked, in milliseconds. Specify Timeout.Infinite to prevent the timer from starting. Specify zero (0) to start the timer immediately.
The delegate specified by the callback parameter is invoked once after dueTime elapses, and thereafter each time the period time interval elapses.
Because the Timer class has the same resolution as the system clock, which is approximately 15 milliseconds on Windows 7 and Windows 8 systems, the callback delegate executes at intervals defined by the resolution of the system clock if period is less than the resolution of the system clock. If period is zero (0) or Timeout.Infinite and dueTime is not Timeout.Infinite, callback is invoked once; the periodic behavior of the timer is disabled, but can be re-enabled using the Change method.
The method specified for callback should be reentrant, because it is called on ThreadPool threads. The method can be executed simultaneously on two thread pool threads if the timer interval is less than the time required to execute the method, or if all thread pool threads are in use and the method is queued multiple times.
