Public ReadOnly Property Item5 As T5

Property Value

T5

Der Wert der fünften Komponente des aktuellen Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>-Objekts.The value of the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object's fifth component.

Examples

Im folgenden Beispiel wird ein 17-Tuple-Objekt erstellt, das auffüllungs Daten für die Stadt von Detroit, Michigan, von 1860 bis 2000 enthält.The following example creates a 17-tuple object that contains population data for the city of Detroit, Michigan, from 1860 to 2000. Die fünfte Komponente des 17-Tupels ist die Population in 1880.The fifth component of the 17-tuple is the population in 1880. Im Beispiel wird die Item5-Eigenschaft verwendet, um den auffüllungs Wert anzuzeigen und um die Jahresrate der Einwohner Wechsel zwischen 1880 und 1890 zu berechnen.The example uses the Item5 property to display the population value and to calculate the annual rate of population change between 1880 and 1890.
