UriTemplateEquivalenceComparer クラス

定義

UriTemplate インスタンスを構造の等価 (参照の等価ではなく) について比較するために使用するクラス。A class used to compare UriTemplate instances for structural (instead of reference) equivalence.

public ref class UriTemplateEquivalenceComparer : System::Collections::Generic::IEqualityComparer<UriTemplate ^>
public class UriTemplateEquivalenceComparer : System.Collections.Generic.IEqualityComparer<UriTemplate>
type UriTemplateEquivalenceComparer = class
    interface IEqualityComparer<UriTemplate>
Public Class UriTemplateEquivalenceComparer
Implements IEqualityComparer(Of UriTemplate)

UriTemplateEquivalenceComparer
実装

次のコード例は、参照の等価と構造の等価の違いを示しています。The following example shows the difference between reference equality and structural equality. また、UriTemplateEquivalenceComparer をディクショナリ内で比較子として使用する方法も示します。It also shows how to use the UriTemplateEquivalenceComparer as a comparer in a dictionary.

// Define two structurally equivalent templates
UriTemplate temp1 = new UriTemplate("weather/{state}/{city}");
UriTemplate temp2 = new UriTemplate("weather/{country}/{village}");

// Notice they are not reference equal, in other words
// they are do not refer to the same object
if (temp1 == temp2)
    Console.WriteLine("{0} and {1} are reference equal", temp1, temp2);
else
    Console.WriteLine("{0} and {1} are NOT reference equal", temp1, temp2);

// Notice they are structrually equal
if (temp1.IsEquivalentTo(temp2))
    Console.WriteLine("{0} and {1} are structurally equal", temp1, temp2);
else
    Console.WriteLine("{0} and {1} are NOT structurally equal", temp1, temp2);

// Create a dictionary and use UriTemplateEquivalenceComparer as the comparer
Dictionary<UriTemplate, object> templates = new Dictionary<UriTemplate, object>(new UriTemplateEquivalenceComparer());

// Add template 1 into the dictionary
templates.Add(temp1, "template1");

// The UriTemplateEquivalenceComparer will be used here to compare the template in the table with template2
// they are structurally equivalent, so ContainsKey will return true.
if (templates.ContainsKey(temp2))
    Console.WriteLine("Both templates hash to the same value");
else
    Console.WriteLine("Both templates do NOT hash to the same value");
'Define two structurally equivalent templates
Dim temp1 As UriTemplate = New UriTemplate("weather/{state}/{city}")
Dim temp2 As UriTemplate = New UriTemplate("weather/{country}/{village}")

'Notice they are not reference equal, in other words
'they are do not refer to the same object
If temp1.Equals(temp2) Then
    Console.WriteLine("{0} and {1} are reference equal", temp1, temp2)
Else
    Console.WriteLine("{0} and {1} are NOT reference equal", temp1, temp2)
End If

'Notice they are structrually equal
If (temp1.IsEquivalentTo(temp2)) Then
    Console.WriteLine("{0} and {1} are structurally equal", temp1, temp2)
Else
    Console.WriteLine("{0} and {1} are NOT structurally equal", temp1, temp2)
End If

'Create a dictionary and use UriTemplateEquivalenceComparer as the comparer
Dim templates As Dictionary(Of UriTemplate, Object) = New Dictionary(Of UriTemplate, Object)(New UriTemplateEquivalenceComparer())

'Add template 1 into the dictionary
templates.Add(temp1, "template1")

'The UriTemplateEquivalenceComparer will be used here to compare the template in the table with template2
'they are structurally equivalent, so ContainsKey will return true.
If (templates.ContainsKey(temp2)) Then
    Console.WriteLine("Both templates hash to the same value")
Else
    Console.WriteLine("Both templates do NOT hash to the same value")
End If

注釈

UriTemplate インスタンスは、既定では参照の等価を使用して比較されます。UriTemplate instances are compared using reference equality by default. UriTemplateEquivalenceComparer クラスは、既定の参照等価検査ではなく、IsEquivalentTo(UriTemplate) を使用して等価性を評価します。The UriTemplateEquivalenceComparer class evaluates equivalence using IsEquivalentTo(UriTemplate) instead of the default reference equality check. このクラスは、厳密な参照の等価の代わりに、URI を基に 2 つの UriTemplate インスタンスを比較する場合に便利です。This class is useful when you wish to compare two UriTemplate instances based on the URIs they match instead of strict reference equality.
