示例1: Equals
//引入命名空間
using System;
using System.Collections;
public class Tuple1Comparer : IEqualityComparer
{
new public bool Equals(object x, object y)
{
// Check if x is a floating point type. If x is, then y is.
if (x is double | x is float)
{
// Convert to Double values.
double dblX = (double) x;
double dblY = (double) y;
if (Double.IsNaN(dblX) | Double.IsInfinity(dblX) |
Double.IsNaN(dblY) | Double.IsInfinity(dblY))
return dblX.Equals(dblY);
else
return Math.Abs(dblX - dblY) <= dblX * .0001;
}
else
{
return x.Equals(y);
}
}
public int GetHashCode(object obj)
{
return obj.GetHashCode();
}
}
public class Example
{
public static void Main()
{
var doubleTuple1 = Tuple.Create(12.3455);
var doubleTuple2 = Tuple.Create(16.8912);
var doubleTuple3 = Tuple.Create(12.3449599);
// Compare first tuple with a Tuple<double> with a different value.
TestEquality(doubleTuple1, doubleTuple2);
//Compare first tuple with a Tuple<double> with the same value.
TestEquality(doubleTuple1, doubleTuple3);
}
private static void TestEquality(Tuple<double> tuple, object obj)
{
Console.WriteLine("{0} = {1}: {2}", tuple.ToString(),
obj.ToString(),
((IStructuralEquatable)tuple).Equals(obj, new Tuple1Comparer()));
}
}輸出：
(12.3455) = (16.8912): False (12.3455) = (12.3449599): True
