示例1: Example
Module Example
Public Sub Main()
' Create an array containing the area of some squares.
Dim areas() As Tuple(Of String, Double) =
{ Tuple.Create("Sitka, Alaska", 2870.3),
Tuple.Create("New York City", 302.6),
Tuple.Create("Los Angeles", 468.7),
Tuple.Create("Detroit", 138.8),
Tuple.Create("Chicago", 227.1),
Tuple.Create("San Diego", 325.2) }
Console.WriteLine("{0,-18} {1,14:N1} {2,30}", "City", "Area (mi.)",
"Equivalent to a square with:")
Console.WriteLine()
For Each area In areas
Console.WriteLine("{0,-18} {1,14:N1} {2,14:N2} miles per side",
area.Item1, area.Item2, Math.Round(Math.Sqrt(area.Item2), 2))
Next
End Sub
End Module輸出：
City Area (mi.) Equivalent to a square with: Sitka, Alaska 2,870.3 53.58 miles per side New York City 302.6 17.40 miles per side Los Angeles 468.7 21.65 miles per side Detroit 138.8 11.78 miles per side Chicago 227.1 15.07 miles per side San Diego 325.2 18.03 miles per side
