Syntax

C#
public void Add<TValue>(
	Accessor<T, IEnumerable<TValue>> accessor,
	IEqualityComparer<TValue> comparer,
	StructuralEqualityComparerOptions options
)
Visual Basic (Declaration)
Public Sub Add(Of TValue) ( _
	accessor As Accessor(Of T, IEnumerable(Of TValue)), _
	comparer As IEqualityComparer(Of TValue), _
	options As StructuralEqualityComparerOptions _
)

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.
options
Type: MbUnit.Framework..::.StructuralEqualityComparerOptions
Some options indicating how to compare the enumeration of values returned by the accessor.

Type Parameters

TValue
The type of the value returned by the accessor.

Remarks

The enumerations of values returned by the accessor are compared 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[] { 5, 4, 3, 2, 1 } };

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