Stopwatch (Clase)

Nota: esta clase es nueva en la versión 2.0 de .NET Framework.

Proporciona un conjunto de métodos y propiedades que se puede utilizar para medir el tiempo transcurrido con precisión.

Espacio de nombres: System.Diagnostics
Ensamblado: System (en system.dll)

public ref class Stopwatch
public class Stopwatch
public class Stopwatch

Una instancia de Stopwatch puede medir el tiempo transcurrido para un intervalo o el total de tiempo transcurrido entre varios intervalos. En un escenario de Stopwatch habitual, se llama al método Start, en otro momento se llama al método Stop y, por último, se comprueba el tiempo transcurrido mediante la propiedad Elapsed.

Una instancia de Stopwatch se está ejecutando o está detenida; utilice IsRunning para determinar el estado actual de Stopwatch. Utilice Start para empezar a medir el tiempo transcurrido; utilice Stop para detener la medida del tiempo transcurrido. Consulte el valor de tiempo transcurrido a través de las propiedades Elapsed, ElapsedMilliseconds o ElapsedTicks. Puede consultar las propiedades de tiempo transcurrido mientras la instancia se está ejecutando o mientras está detenida. Las propiedades de tiempo transcurrido aumentan continuamente mientras se ejecuta Stopwatch; permanecen constantes cuando la instancia está detenida.

De manera predeterminada, el valor de tiempo transcurrido de una instancia de Stopwatch es igual al total de todos los intervalos de tiempo medidos. Cada llamada a Start inicia la cuenta del tiempo transcurrido acumulado; cada llamada a Stop finaliza la medición del intervalo actual y bloquea el valor de tiempo transcurrido acumulado. Utilice el método Reset para borrar el tiempo transcurrido acumulado en una instancia de Stopwatch existente.

Stopwatch mide el tiempo transcurrido contando pasos del temporizador en el mecanismo de temporización subyacente. Si el hardware instalado y el sistema operativo admiten un contador de rendimiento de alta resolución, la clase Stopwatch utiliza ese contador para medir el tiempo transcurrido. De lo contrario, la clase Stopwatch utiliza el temporizador del sistema para medir el tiempo transcurrido. Utilice los campos Frequency y IsHighResolution para determinar la precisión y la resolución de la implementación de control de tiempo de Stopwatch.

La clase Stopwatch ayuda en la manipulación de contadores de rendimiento relacionados con el control de tiempo dentro del código administrado. Específicamente, el campo Frequency y el método GetTimestamp pueden utilizarse en lugar de QueryPerformanceFrequency y QueryPerformanceCounter de las API Win32 no administradas.

NotaNota

En un equipo con varios procesadores, no importa en qué procesador se ejecuta el subproceso. Sin embargo, debido a errores del BIOS o de la Capa de abstracción de hardware (HAL), se pueden obtener diferentes resultados de control de tiempo en diferentes procesadores. Para especificar la afinidad del procesador para un subproceso, utilice el método ProcessThread.ProcessorAffinity.

En el ejemplo siguiente se utiliza la clase Stopwatch para implementar las operaciones de cronómetro de una aplicación de Windows Forms.
