Tuple(Of T1, T2, T3, T4, T5, T6, T7).Item7 Property

Gets the value of the current Tuple(Of T1, T2, T3, T4, T5, T6, T7) object's seventh component.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public ReadOnly Property Item7 As T7

Property Value

Type: T7
The value of the current Tuple(Of T1, T2, T3, T4, T5, T6, T7) object's seventh component.

You can dynamically determine the type of the Item7 component in one of two ways:

The following example defines an array of Tuple(Of 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. It then displays a table that lists the data. To display the population in 2000, it retrieves the value of the Item7 property for each Tuple(Of T1, T2, T3, T4, T5, T6, T7) object.

Module Example
   Public Sub Main()
      ' Create tuples containing population data for New York, Chicago,  
      ' and Los Angeles, 1960-2000. 
      Dim cities() =
           { Tuple.Create("New York", 7891957, 7781984, 7894862, 
                          7071639, 7322564, 8008278),
             Tuple.Create("Los Angeles", 1970358, 2479015, 2816061, 
                          2966850, 3485398, 3694820),
             Tuple.Create("Chicago", 3620962, 3550904, 3366957, 
                          3005072, 2783726, 2896016) }

      ' Display tuple data in table. 
      Dim header As String = "Population in"
      Console.WriteLine("{0,-12} {1,66}", 
                        "City", New String("-"c,(66-header.Length)\2) + header + _
                                New String("-"c, (66-header.Length)\2))
      Console.WriteLine("{0,24}{1,11}{2,11}{3,11}{4,11}{5,11}", 
                        "1950", "1960", "1970", "1980", "1990", "2000")                  
      Console.WriteLine()
      For Each city In cities                      
         Console.WriteLine("{0,-12} {1,11:N0}{2,11:N0}{3,11:N0}{4,11:N0}{5,11:N0}{6,11:N0}", 
                           city.Item1, city.Item2, city.Item3, city.Item4, 
                           city.Item5, city.Item6, city.Item7)
      Next 
   End Sub
