'Declaration
Public ReadOnly Property Item1 As T1

Property Value

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

You can dynamically determine the type of the Item1 component in one of two ways:

  • By calling the GetType method on the value that is returned by the Item1 property.

  • By retrieving the Type object that represents the Tuple(Of T1, T2, T3, T4) object, and retrieving the first element from the array that is returned by its Type.GetGenericArguments method.

The following example defines an array of Tuple(Of T1, T2, T3, T4) objects whose components contain the name of a city, a month of the year, and the average high and low temperatures for that month. It then retrieves and displays the value of each component.
