Public ReadOnly Property Item4 As T4

Property Value

T4

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

Examples

Im folgenden Beispiel wird ein Array von Tuple<T1,T2,T3,T4,T5,T6,T7> Objekten definiert, deren Komponenten auffüllungs Daten für drei US-amerikanische Städte (New York, Chicago und Los Angeles) zwischen 1950 und 2000 enthalten.The following example defines an array of Tuple<T1,T2,T3,T4,T5,T6,T7> objects whose components contain population data for three U.S. cities (New York, Chicago, and Los Angeles) from 1950 through 2000. Daraufhin wird eine Tabelle angezeigt, in der die Daten aufgelistet sind.It then displays a table that lists the data. Um die Auffüllung in 1970 anzuzeigen, ruft Sie den Wert der Item4-Eigenschaft für jedes Tuple<T1,T2,T3,T4,T5,T6,T7>-Objekt ab.To display the population in 1970, it retrieves the value of the Item4 property for each Tuple<T1,T2,T3,T4,T5,T6,T7> object.
