示例1: Equals
//引入命名空间
using System;
using System.Collections;
public class Item2Comparer<T1, T2> : IEqualityComparer
{
new public bool Equals(object x, object y)
{
// Return true for all values of Item1.
if (x is T1)
//if (typeof(x) is string)
return true;
else
return x.Equals(y);
}
public int GetHashCode(object obj)
{
if (obj is T1)
return ((T1) obj).GetHashCode();
else
return ((T2) obj).GetHashCode();
}
}
public class Example
{
public static void Main()
{
Tuple<string, double>[] distancesWalked = {
Tuple.Create("Jan", Double.NaN),
Tuple.Create("Joe", Double.NaN),
Tuple.Create("Adam", 1.36),
Tuple.Create("Selena", 2.01),
Tuple.Create("Jake", 1.36) };
for (int ctr = 0; ctr < distancesWalked.Length; ctr++)
{
Tuple<string, double> distanceWalked = distancesWalked[ctr];
for (int ctr2 = ctr + 1; ctr2 < distancesWalked.Length; ctr2++)
{
Console.WriteLine("{0} = {1}: {2}", distanceWalked,
distancesWalked[ctr2],
((IStructuralEquatable)distanceWalked).Equals(distancesWalked[ctr2],
new Item2Comparer<string, double>()));
}
Console.WriteLine();
}
}
}输出：
(Jan, NaN) = (Joe, NaN): True (Jan, NaN) = (Adam, 1.36): False (Jan, NaN) = (Selena, 2.01): False (Jan, NaN) = (Jake, 1.36): False (Joe, NaN) = (Adam, 1.36): False (Joe, NaN) = (Selena, 2.01): False (Joe, NaN) = (Jake, 1.36): False (Adam, 1.36) = (Selena, 2.01): False (Adam, 1.36) = (Jake, 1.36): True (Selena, 2.01) = (Jake, 1.36): False
