using System.Collections.Generic;
public class Example
{
public static void Main()
{
Tuple<string, decimal, int, int>[] pitchers =

Tuple.Create("Blair, Jack", 168.1m, 146, 65),

Tuple.Create("Lee, Adam", 137.2m, 109, 45),
Tuple.Create("Rohr, Don", 101.0m, 110, 42) };
Tuple<string, double, double, double>[] results= ComputeStatistics(pitchers);
// Display the results.
Console.WriteLine("{0,-20} {1,9} {2,11} {3,15}\n",

private static Tuple<string, double, double, double>[] ComputeStatistics(Tuple<string, decimal, int, int>[] pitchers)
{
var list = new List<Tuple<string, double, double, double>>();
Tuple<string, double, double, double> result;
foreach (var pitcher in pitchers)
{
// Decimal portion of innings pitched represents 1/3 of an inning
double innings = (double) Math.Truncate(pitcher.Item2);
innings = innings + (((double)pitcher.Item2 - innings) * .33);
double ERA = pitcher.Item4/innings * 9;
double hitsPerInning = pitcher.Item3/innings;
double EI = (ERA * 2 + hitsPerInning * 9)/3;

}
return list.ToArray();
}
}输出：
