示例1: Main
//引入命名空间
using System;
public class Example
{
public static void Main()
{
// Get population data for New York City, 1950-2000.
var population = Tuple.Create("New York", 7891957, 7781984,
7894862, 7071639, 7322564, 8008278);
var rate = ComputePopulationChange(population);
// Display results.
Console.WriteLine("Population Change, {0}, 1950-2000\n", population.Item1);
Console.WriteLine("Year {0,10} {1,9}", "Population", "Annual Rate");
Console.WriteLine("1950 {0,10:N0} {1,11}", population.Item2, "NA");
Console.WriteLine("1960 {0,10:N0} {1,11:P2}", population.Item3, rate.Item2/10);
Console.WriteLine("1970 {0,10:N0} {1,11:P2}", population.Item4, rate.Item3/10);
Console.WriteLine("1980 {0,10:N0} {1,11:P2}", population.Item5, rate.Item4/10);
Console.WriteLine("1990 {0,10:N0} {1,11:P2}", population.Item6, rate.Item5/10);
Console.WriteLine("2000 {0,10:N0} {1,11:P2}", population.Item7, rate.Item6/10);
Console.WriteLine("1950-2000 {0,10:N0} {1,11:P2}", "", rate.Item7/50);
}
private static Tuple<string, double, double, double, double, double, double>
ComputePopulationChange(
Tuple<string, int, int, int, int, int, int> data)
{
var rate = Tuple.Create(data.Item1,
(double)(data.Item3 - data.Item2)/data.Item2,
(double)(data.Item4 - data.Item3)/data.Item3,
(double)(data.Item5 - data.Item4)/data.Item4,
(double)(data.Item6 - data.Item5)/data.Item5,
(double)(data.Item7 - data.Item6)/data.Item6,
(double)(data.Item7 - data.Item2)/data.Item2 );
return rate;
}
}输出：
