Implements a timer that raises an event at user-defined intervals. This timer is optimized for use in Windows Forms applications and must be used in a window.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Thetype exposes the following members.
|CanRaiseEvents||Gets a value indicating whether the component can raise an event. (Inherited from Component.)|
|Container||Gets the IContainer that contains the Component. (Inherited from Component.)|
|DesignMode||Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)|
|Enabled||Gets or sets whether the timer is running.|
|Events||Gets the list of event handlers that are attached to this Component. (Inherited from Component.)|
|Interval||Gets or sets the time, in milliseconds, before the Tick event is raised relative to the last occurrence of the Tick event.|
|Site||Gets or sets the ISite of the Component. (Inherited from Component.)|
|Tag||Gets or sets an arbitrary string representing some type of user state.|
|CreateObjRef||Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)|
|Dispose()||Releases all resources used by the Component. (Inherited from Component.)|
|Dispose(Boolean)||Disposes of the resources, other than memory, used by the timer. (Overrides Component.Dispose(Boolean).)|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetLifetimeService||Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|GetService||Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|InitializeLifetimeService||Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|MemberwiseClone()||Creates a shallow copy of the current Object. (Inherited from Object.)|
|MemberwiseClone(Boolean)||Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)|
|OnTick||Raises the Tick event.|
|Start||Starts the timer.|
|Stop||Stops the timer.|
|ToString||Infrastructure. Returns a string that represents the . (Overrides Component.ToString().)|
A is used to raise an event at user-defined intervals. This Windows timer is designed for a single-threaded environment where UI threads are used to perform processing. It requires that the user code have a UI message pump available and always operate from the same thread, or marshal the call onto another thread.
When you use this timer, use the Tick event to perform a polling operation or to display a splash screen for a specified period of time. Whenever the Enabled property is set to true and the Interval property is greater than zero, the Tick event is raised at intervals based on the Interval property setting.
This class provides methods to set the interval, and to start and stop the timer.
The following example implements a simple interval timer, which sets off an alarm every five seconds. When the alarm occurs, a MessageBox displays a count of the number of times the alarm has started and prompts the user as to whether the timer should continue to run.
