Valor de los restantes componente del objeto Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> actual.The value of the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object's remaining components.

Ejemplos

En el ejemplo siguiente se crea un objeto de 17 tupla que contiene los datos de población de la ciudad de Detroit, Michigan, de 1860 a 2000.The following example creates a 17-tuple object that contains population data for the city of Detroit, Michigan, from 1860 to 2000. El séptimo componente de la tupla de 17 es la población en 1900.The seventh component of the 17-tuple is the population in 1900. En el ejemplo se Rest usa la propiedad para recuperar los valores de los componentes del octavo al decimocuarto y Rest se usa la Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> propiedad del objeto anidado para recuperar los valores de los componentes restantes.The example uses the Rest property to retrieve the values of the eighth through fourteenth components, and it uses the Rest property of the nested Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object to retrieve the values of the remaining components.

La Rest propiedad devuelve un Tuple objeto anidado que permite el acceso a los componentes octavo a nde la tupla.The Rest property returns a nested Tuple object that allows access to the eighth though nth components of the tuple. En función del número total de componentes de la tupla, los valores de los componentes octavo a decimocuarta se pueden recuperar de las propiedades del Tuple Item1 objeto anidado Item7 a través de.Depending on the total number of components in the tuple, the values of the eighth through fourteenth components can be retrieved from the nested Tuple object's Item1 through Item7 properties. Después, puede usar la Rest propiedad de un Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objeto anidado para recuperar el Tuple objeto en el siguiente nivel de anidamiento.You can then use the Rest property of a nested Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object to retrieve the Tuple object at the next level of nesting.

Puede determinar de forma dinámica el número de componentes en un Tuple objeto anidado devuelto por la Rest propiedad extrayendo el dígito de su nombre de tipo.You can dynamically determine the number of components in a nested Tuple object that is returned by the Rest property by extracting the digit from its type name. Esto se muestra en el ejemplo siguiente.The following example provides an illustration.
