获取或设置引发 Elapsed 事件的间隔（以毫秒为单位）。

public: property double Interval { double get(); void set(double value); }; public double Interval { get; set; } [System.Timers.TimersDescription("TimerInterval")] public double Interval { get; set; } [System.Timers.TimersDescription("TimerInterval")] [System.ComponentModel.SettingsBindable(true)] public double Interval { get; set; } member this.Interval : double with get, set [] member this.Interval : double with get, set [] [] member this.Interval : double with get, set Public Property Interval As Double 属性值 Double

Elapsed 事件之间经过的时间（以毫秒为单位）。该值必须大于零，并且必须小于或等于 Int32.MaxValue。默认值为 100 毫秒。

属性 TimersDescriptionAttribute SettingsBindableAttribute 例外 ArgumentException

间隔小于或等于零。

- 或 -

间隔大于 Int32.MaxValue，并且计时器当前已启用。（如果当前未启用计时器，则在启用它之前不会引发异常。）

示例

以下示例实例化一个 Timer 对象，该 Timer.Elapsed 对象每两秒 (2000 毫秒) 触发一次事件，为事件设置事件处理程序，并启动计时器。事件处理程序会在每次引发属性时显示该属性的值 ElapsedEventArgs.SignalTime 。

using namespace System; using namespace System::Timers; public ref class Example { private: static System::Timers::Timer^ aTimer; public: static void Demo() { // Create a timer and set a two second interval. aTimer = gcnew System::Timers::Timer(); aTimer->Interval = 2000; // Hook up the Elapsed event for the timer. aTimer->Elapsed += gcnew System::Timers::ElapsedEventHandler(Example::OnTimedEvent); // Have the timer fire repeated events (true is the default) aTimer->AutoReset = true; // Start the timer aTimer->Enabled = true; Console::WriteLine("Press the Enter key to exit the program at any time... "); Console::ReadLine(); } private: static void OnTimedEvent(Object^ source, System::Timers::ElapsedEventArgs^ e) { Console::WriteLine("The Elapsed event was raised at {0}", e->SignalTime); } }; int main() { Example::Demo(); } // The example displays output like the following: // Press the Enter key to exit the program at any time... // The Elapsed event was raised at 5/20/2015 8:48:58 PM // The Elapsed event was raised at 5/20/2015 8:49:00 PM // The Elapsed event was raised at 5/20/2015 8:49:02 PM // The Elapsed event was raised at 5/20/2015 8:49:04 PM // The Elapsed event was raised at 5/20/2015 8:49:06 PM using System; using System.Timers; public class Example { private static Timer aTimer; public static void Main() { // Create a timer and set a two second interval. aTimer = new System.Timers.Timer(); aTimer.Interval = 2000; // Hook up the Elapsed event for the timer. aTimer.Elapsed += OnTimedEvent; // Have the timer fire repeated events (true is the default) aTimer.AutoReset = true; // Start the timer aTimer.Enabled = true; Console.WriteLine("Press the Enter key to exit the program at any time... "); Console.ReadLine(); } private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e) { Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime); } } // The example displays output like the following: // Press the Enter key to exit the program at any time... // The Elapsed event was raised at 5/20/2015 8:48:58 PM // The Elapsed event was raised at 5/20/2015 8:49:00 PM // The Elapsed event was raised at 5/20/2015 8:49:02 PM // The Elapsed event was raised at 5/20/2015 8:49:04 PM // The Elapsed event was raised at 5/20/2015 8:49:06 PM open System.Timers let onTimedEvent source (e: ElapsedEventArgs) = printfn $"The Elapsed event was raised at {e.SignalTime}" // Create a timer and set a two second interval. let aTimer = new Timer() aTimer.Interval
