public AndWhichConstraint<TAssertions,T> ContainEquivalentOf<TExpectation>( 
   TExpectation expectation,
   Func<EquivalencyOptions<TExpectation>,EquivalencyOptions<TExpectation>> config,
   string because,
   params object[] becauseArgs
)

Parameters

expectation

The expected element.

config

A reference to the FluentAssertions.Equivalency.EquivalencyOptions<TExpectation> configuration object that can be used to influence the way the object graphs are compared. You can also provide an alternative instance of the FluentAssertions.Equivalency.EquivalencyOptions<TExpectation> class. The global defaults are determined by the FluentAssertions.AssertionConfiguration class.

because

A formatted phrase as is supported by System.String.Format(System.String,System.Object[]) explaining why the assertion is needed. If the phrase does not start with the word because, it is prepended automatically.

becauseArgs

Zero or more objects to format using the placeholders in because.

Type Parameters

TExpectation

Important: You cannot use this method to assert whether a subset of the collection is equivalent to the expectation. This usually means that the expectation is meant to be a single item.

By default, objects within the collection are seen as equivalent to the expected object when both object graphs have equally named properties with the same value, irrespective of the type of those objects. Notice that actual behavior is determined by the global defaults managed by FluentAssertions.AssertionConfiguration.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
