Syntax

public sealed class MappedComparer<T1, T2> : IEqualityComparer<T1>

Type Parameters

Name	Description
T1	The argument type of the mapping.
T2	The return type of the mapping.

Constructors

MappedComparer(Func<T1, T2>)

Creates an equality comparer that first applies a mapping and then compares the results using the default comparer.

Declaration

public MappedComparer(Func<T1, T2> transform)

Parameters

Type	Name	Description
System.Func<T1, T2>	transform	A mapping that takes an element and transforms it before it is compared.

MappedComparer(Func<T1, T2>, IEqualityComparer<T2>)

Creates an equality comparer that first applies a mapping and then compares the results using a custom comparer.

Declaration

public MappedComparer(Func<T1, T2> transform, IEqualityComparer<T2> resultComparer)

Parameters

Type	Name	Description
System.Func<T1, T2>	transform	A mapping that takes an element and transforms it before it is compared.
System.Collections.Generic.IEqualityComparer<T2>	resultComparer	A comparer for the results of transform.

Fields

ResultComparer

An equality comparer for values of type T2.

Declaration

public readonly IEqualityComparer<T2> ResultComparer

Field Value

Type	Description
System.Collections.Generic.IEqualityComparer<T2>

Transform

Takes a value of type T1 and maps it to a value of type T2.

Declaration

public readonly Func<T1, T2> Transform

Field Value

Type	Description
System.Func<T1, T2>

Methods

Equals(T1, T1)

Tests if two values are equal.

Declaration

public bool Equals(T1 x, T1 y)

Parameters

Type	Name	Description
T1	x	The first value to compare.
T1	y	The second value to compare.

Returns

Type	Description
System.Boolean

GetHashCode(T1)

Computes a hash code for a value.

Declaration

public int GetHashCode(T1 obj)

Parameters

Type	Name	Description
T1	obj	The value to compute a hash code for.

Returns

Type	Description
System.Int32	A hash code.
