Adds a matching criterion to the structural equality comparer.

Namespace: MbUnit.Framework
Assembly: MbUnit (in MbUnit.dll) Version: 3.3.0.0 (3.3.610.0)

Syntax

C#
public void Add<TValue>( Accessor<T, IEnumerable<TValue>> accessor, IEqualityComparer<TValue> comparer )

Visual Basic (Declaration)
Public Sub Add(Of TValue) ( _ accessor As Accessor(Of T, IEnumerable(Of TValue)), _ comparer As IEqualityComparer(Of TValue) _ )

Parameters

accessor: Type: Gallio.Common..::.Accessor<(Of <(T, IEnumerable<(Of <(TValue>)>)>)>)
An accessor that gets an enumeration of values from the tested object.

comparer: Type: System.Collections.Generic..::.IEqualityComparer<(Of <(TValue>)>)
A comparer instance for the values returned by the accessor, or null to use the default one.

Type Parameters

TValue: The type of the value returned by the accessor.

Remarks

The enumerations of values returned by the accessor are compared one by one, by using the specified comparer.

Examples

CopyC#

public class Foo
{
    public int[] Values;
}

[TestFixture]
public class FooTest
{
    [Test]
    public void MyTest()
    {
        var foo1 = new Foo() { Values = new int[] { 1, 2, 3, 4, 5 } };    
        var foo2 = new Foo() { Values = new int[] { 1, 2, 3, 4, 5 } };

        Assert.AreEqual(foo1, foo2, new StructuralEqualityComparer<Foo>
        {
            { x => x.Values,
              new StructuralEqualityComparer<int> { { x => x } }
            },
        });
    }
}

Exceptions

Exception	Condition
System..::.ArgumentNullException	The specified accessor argument is a null reference.
