出门在外也不愁Timer.Interval 属性 (System.Timers)
Interval 属性
此文章由机器翻译。 将光标移到文章的句子上，以查看原文。
Timer.Interval 属性
.NET Framework (current version)
System（System.dll 中）
[TimersDescriptionAttribute("TimerInterval")]
[SettingsBindableAttribute(true)]
public double Interval { get; set; }
MaxValue。默认值为 100 毫秒。
间隔是小于或等于零。- 或 -MaxValue, ，和当前启用计时器。 属性来确定所依照的频率
触发事件。 属性小于系统时钟的分辨率。 属性设置为 5 毫秒为单位）。在上运行时 Windows 7 其系统时钟具有大约 15 毫秒，引发该事件的分辨率大约每隔 15 毫秒，而不是每隔 5 毫秒的系统。
using System.IO;
using System.Collections.G
using System.T
public class Example
private static Timer aT
private static List&String&
private static int nEventsFired = 0;
private static DateTime previousT
public static void Main()
eventlog = new List&String&();
StreamWriter sr = new StreamWriter(@".\Interval.txt");
// Create a timer with a five millisecond interval.
aTimer = new Timer(5);
aTimer.Elapsed += OnTimedE
// Hook up the Elapsed event for the timer.
aTimer.AutoReset = true;
sr.WriteLine("The timer should fire every {0} milliseconds.",
aTimer.Interval);
aTimer.Enabled = true;
Console.WriteLine("Press the Enter key to exit the program... ");
Console.ReadLine();
foreach (var item in eventlog)
sr.WriteLine(item);
sr.Close();
Console.WriteLine("Terminating the application...");
private static void OnTimedEvent(Object source, ElapsedEventArgs e)
eventlog.Add(String.Format("Elapsed event at {0:HH':'mm':'ss.ffffff} ({1})",
e.SignalTime,
nEventsFired++ == 0 ?
0.0 : (e.SignalTime - previousTime).TotalMilliseconds));
previousTime = e.SignalT
if (nEventsFired == 20) {
Console.WriteLine("No more events will fire...");
aTimer.Enabled = false;
// The example writes output like the following to a file:
The timer should fire every 5 milliseconds.
Elapsed event at 08:42:49.)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..002)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..002)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
Elapsed event at 08:42:49..0015)
下面的代码可用于确定当前的系统上的系统时钟的分辨率：
using System.Runtime.InteropS
public class Example
[DllImport("kernel32.dll", SetLastError=true)]
static extern bool GetSystemTimeAdjustment(out long lpTimeAdjustment,
out long lpTimeIncrement,
out bool lpTimeAdjustmentDisabled);
public static void Main()
long timeAdjustment, timeIncrement = 0;
bool timeAdjustmentD
if (GetSystemTimeAdjustment(out timeAdjustment, out timeIncrement,
out timeAdjustmentDisabled)) {
if (! timeAdjustmentDisabled)
Console.WriteLine("System clock resolution: {0:N3} milliseconds",
timeIncrement/10000.0);
Console.WriteLine("Unable to determine system clock resolution.");
// The example displays output like the following:
System clock resolution: 15.600 milliseconds
属性设置为 true, ，在时间开始计数
设置。 已设置为 true。 设置为 true 和
设置为 false, ，则
事件仅当第一次间隔到期。 然后将设置为 false。注意 和
都设置为 false, ，和计时器以前已启用，设置
属性会导致
事件，它会引发一次，就像
属性必须设置为 true。 属性设置为 true, ，设置
属性设置为所需的时间间隔，然后立即将设置
属性改回 false。Elapsed 事件每隔两秒钟 （2000年毫秒），设置事件处理程序对于事件，并启动计时器。 属性每次都会引发该事件。
// Use this code inside a project created with the Visual C# & Windows Desktop & Console Application template.
// Replace the code in Program.cs with this code.
// To avoid confusion with other Timer classes, this sample always uses the fully-qualified
// name of System.Timers.Timer instead of a using statement for System.Timers.
public class Example
private static System.Timers.Timer aT
public static void Main()
// Normally, the timer is declared at the class level, so that it stays in scope as long as it
// is needed. If the timer is declared in a long-running method, KeepAlive must be used to prevent
// the JIT compiler from allowing aggressive garbage collection to occur before the method ends.
// You can experiment with this by commenting out the class-level declaration and uncommenting
// t then uncomment the GC.KeepAlive(aTimer) at the end of the method.
//System.Timers.Timer aT
// Create a timer and set a two second interval.
aTimer = new System.Timers.Timer();
aTimer.Interval = 2000;
// Alternate method: create a Timer with an interval argument to the constructor.
//aTimer = new System.Timers.Timer(2000);
// Create a timer with a two second interval.
aTimer = new System.Timers.Timer(2000);
// Hook up the Elapsed event for the timer.
aTimer.Elapsed += OnTimedE
// 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();
// If the timer is declared in a long-running method, use KeepAlive to prevent garbage collection
// from occurring before the method ends.
//GC.KeepAlive(aTimer)
private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e)
Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
// This 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/:58 PM
The Elapsed event was raised at 5/20/:00 PM
The Elapsed event was raised at 5/20/:02 PM
The Elapsed event was raised at 5/20/:04 PM
The Elapsed event was raised at 5/20/:06 PM
.NET Framework1.1 后可用

开发人员中心如果要求设置定时器时间间隔为0.5秒，那么它的Interval属性值应该等于？_百度知道
如果要求设置定时器时间间隔为0.5秒，那么它的Interval属性值应该等于？
A.5秒. 50D. 500C，那么它的Interval属性值应该等于. 5000B如果要求设置定时器时间间隔为0
我有更好的答案
因0单位是毫秒, 则选B
500.5s=500ms
