示例1: Main
//引入命名空間
using System;
public class Example
{
public static void Main()
{
Tuple<string, double, int>[] scores =
{ Tuple.Create("Jack", 78.8, 8),
Tuple.Create("Abbey", 92.1, 9),
Tuple.Create("Dave", 88.3, 9),
Tuple.Create("Sam", 91.7, 8),
Tuple.Create("Ed", 71.2, 5),
Tuple.Create("Penelope", 82.9, 8),
Tuple.Create("Linda", 99.0, 9),
Tuple.Create("Judith", 84.3, 9) };
var result = ComputeStatistics(scores);
Console.WriteLine("Mean score: {0:N2} (SD={1:N2}) (n={2})",
result.Item2, result.Item3, result.Item1);
}
private static Tuple<int, double, double> ComputeStatistics(Tuple<string, double, int>[] scores)
{
int n = 0;
double sum = 0;
// Compute the mean.
foreach (var score in scores)
{
n += score.Item3;
sum += score.Item2 * score.Item3;
}
double mean = sum / n;
// Compute the standard deviation.
double ss = 0;
foreach (var score in scores)
{
ss = Math.Pow(score.Item2 - mean, 2);
}
double sd = Math.Sqrt(ss/scores.Length);
return Tuple.Create(scores.Length, mean, sd);
}
}輸出：
Mean score: 87.02 (SD=0.96) (n=8)
