Dim comparer As IComparer 

CollectionAssert.AreEqual(expected, actual, comparer)

public static void AreEqual(
    ICollection expected,
    ICollection actual,
    IComparer comparer

    IComparer^ comparer
)

public static function AreEqual(
    expected : ICollection, 
    actual : ICollection, 
    comparer : IComparer
)

Parameters

• expected
  Type: System.Collections.ICollection

  The first collection to compare. This is the collection the unit test expects.

• actual
  Type: System.Collections.ICollection

  The second collection to compare. This is the collection the unit test produced.

• comparer
  Type: System.Collections.IComparer

  The compare implementation to use when comparing elements of the collection.

Exceptions

Remarks

Two collections are equal if they have the same elements in the same order and quantity. Elements are equal if their values are equal, not if they refer to the same object.
