Tuple<T1, T2>.Item2 Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the value of the current Tuple<T1, T2> object's second component.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public ReadOnly Property Item2 As T2
public T2 Item2 { get; }
Property Value
Type: T2
The value of the current Tuple<T1, T2> object's second 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> object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.
Examples
The example illustrates the use of the Item1 and Item2 properties to define a method that returns multiple values in the form of a 2-tuple.
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim dividend, divisor As Integer
Dim result As Tuple(Of Integer, Integer)
dividend = 136945 : divisor = 178
result = IntegerDivide(dividend, divisor)
If result IsNot Nothing Then
outputBlock.Text += String.Format("{0} \ {1} = {2}, remainder {3}", _
dividend, divisor, result.Item1, result.Item2) + vbCrLf
Else
outputBlock.Text += String.Format("{0} \ {1} = <Error>", dividend, divisor) & vbCrLf
End If
dividend = Int32.MaxValue : divisor = -2073
result = IntegerDivide(dividend, divisor)
If result IsNot Nothing Then
outputBlock.Text += String.Format("{0} \ {1} = {2}, remainder {3}", _
dividend, divisor, result.Item1, result.Item2) + vbCrLf
Else
outputBlock.Text += String.Format("{0} \ {1} = <Error>", dividend, divisor) & vbCrLf
End If
End Sub
