Tuple<T1, T2, T3, T4, T5>.Item5 Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the value of the current Tuple<T1, T2, T3, T4, T5> object's fifth component.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public ReadOnly Property Item5 As T5
public T5 Item5 { get; }
Property Value
Type: T5
The value of the current Tuple<T1, T2, T3, T4, T5> object's fifth component.
Remarks
You can dynamically determine the type of the Item2 component in one of two ways:
By calling the GetType method on the value that is returned by the Item2 property.
By retrieving the Type object that represents the Tuple<T1, T2, T3, T4> object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.
Examples
The following example defines an array of Tuple<T1, T2, T3, T4, T5> objects whose components contain the name of a state in the United Dates, its population in 1990 and 2000, its population change in this 10-year period, and the percentage change in its population. It then iterates through the array and displays the value of each component in a tuple.
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
outputBlock.FontFamily = New System.Windows.Media.FontFamily("Courier New")
' Define array of tuples reflecting population change by state, 1990-2000.
Dim statesData() = _
{ Tuple.Create("California", 29760021, 33871648, 4111627, 13.8), _
Tuple.Create("Illinois", 11430602, 12419293, 988691, 8.6), _
Tuple.Create("Washington", 4866692, 5894121, 1027429, 21.1) }
' Display the items of each tuple
outputBlock.Text += String.Format("{0,-12}{1,18}{2,18}{3,15}{4,12}", "State", "Population 1990", _
"Population 2000", "Change", "% Change") & vbCrLf
outputBlock.Text &= vbCrLf
For Each stateData As Tuple(Of String, Integer, Integer, Integer, Double) In statesData
outputBlock.Text += String.Format("{0,-12}{1,18:N0}{2,18:N0}{3,15:N0}{4,12:P1}", _
stateData.Item1, stateData.Item2, _
stateData.Item3, stateData.Item4, stateData.Item5 / 100) & vbCrLf
Next
End Sub
