    Syntax

   string expectationMemberName,
   string subjectMemberName
)

    Parameters

    expectationMemberName
    A field or property name indicating the member to map from.
    subjectMemberName
    A field or property name indicating the member to map to.

    Type Parameters

    TNestedExpectation
    TNestedSubject
    Remarks
    Only direct members of TNestedExpectation and TNestedSubject can be mapped to each other, so no . or [] are allowed. Those types can appear anywhere in the object graphs that are being compared. If the types of the members are different, the usual logic applies depending or not if conversion options were specified. Fields can be mapped to properties and vice-versa.
