Tuple<T1, T2, T3, T4, T5, T6, T7, TRest>::Item4 Property
Gets the value of the current Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object's fourth component.
Assembly: mscorlib (in mscorlib.dll)
You can dynamically determine the type of the Item4 component in one of two ways:
By calling the GetType method on the value that is returned by the Item4 property.
By retrieving the Type object that represents the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object, and retrieving the fourth element from the array that is returned by its Type::GetGenericArguments method.
The following example creates a 17-tuple object that contains population data for the city of Detroit, Michigan, from 1860 to 2000. The fourth component of the 17-tuple is the population in 1870. The example uses the Item4 property to display the population value and to calculate the annual rate of population change between 1870 and 1880.
