示例1: PopulationComparer
//引入命名空间

public PopulationComparer(int component, bool descending)
{
if (! descending) multiplier = 1;
if (component <= 0 || component > 6)
throw new ArgumentException("The component argument is out of range.");
itemPosition = component;
}
public int Compare(object x, object y)
{
var tX = x as Tuple<T1, T2, T3, T4, T5, T6>;
if (tX == null)
{
return 0;
}
else

var tY = y as Tuple<T1, T2, T3, T4, T5, T6>;
switch (itemPosition)
{
case 1:
return Comparer<T1>.Default.Compare(tX.Item1, tY.Item1) * multiplier;
case 2:
return Comparer<T2>.Default.Compare(tX.Item2, tY.Item2) * multiplier;

case 5:

case 6:
return Comparer<T6>.Default.Compare(tX.Item6, tY.Item6) * multiplier;

public class Example
{
public static void Main()
{
// Create array of sextuple with population data for three U.S.
// cities, 1960-2000.
Tuple<string, int, int, int, int, int>[] cities =
{ Tuple.Create("Los Angeles", 2479015, 2816061, 2966850, 3485398, 3694820),
Tuple.Create("New York", 7781984, 7894862, 7071639, 7322564, 8008278),
Tuple.Create("Chicago", 3550904, 3366957, 3005072, 2783726, 2896016) };
// Display array in unsorted order.
Console.WriteLine("In unsorted order:");
foreach (var city in cities)
Console.WriteLine(city.ToString());
Console.WriteLine();
Array.Sort(cities, new PopulationComparer<string, int, int, int, int, int>(3));
// Display array in sorted order.
Console.WriteLine("Sorted by population in 1970:");
foreach (var city in cities)
Console.WriteLine(city.ToString());
Console.WriteLine();
Array.Sort(cities, new PopulationComparer<string, int, int, int, int, int>(6));
// Display array in sorted order.
Console.WriteLine("Sorted by population in 2000:");
foreach (var city in cities)
Console.WriteLine(city.ToString());
}
}
输出:
