- CollectionItemsEqualConstraint
CollectionItemsEqualConstraint is the abstract base class for all collection constraints that apply some notion of item equality as a part of their operation.
- CollectionOperator
Abstract base for operators that indicate how to apply a constraint to items in a collection.
- CollectionOrderedConstraint

- ComparisonAdapter
ComparisonAdapter class centralizes all comparisons of values in NUnit, adapting to the use of any provided IComparer, IComparer<T> or Comparison<T>.
- ComparisonConstraint
Abstract base class for constraints that compare values to determine if one is greater than, equal to or less than the other.
- Constraint
The Constraint class is the base of all built-in constraints within NUnit. It provides the operator overloads used to combine constraints.
- ConstraintBuilder
ConstraintBuilder maintains the stacks that are used in processing a ConstraintExpression. An OperatorStack is used to hold operators that are waiting for their operands to be reorganized. a ConstraintStack holds input constraints as well as the results of each operator applied.
- ConstraintBuilder.ConstraintStack
ConstraintStack is a type-safe stack for holding Constraints
- ConstraintExpression
ConstraintExpression represents a compound constraint in the process of being constructed from a series of syntactic elements.
Individual elements are appended to the expression as they are reorganized. When a constraint is appended, it is returned as the value of the operation so that modifiers may be applied. However, any partially built expression is attached to the constraint for later resolution. When an operator is appended, the partial expression is returned. If it's a self-resolving operator, then a ResolvableConstraintExpression is returned.
- ConstraintOperator
The ConstraintOperator class is used internally by a ConstraintBuilder to represent an operator that modifies or combines constraints.
Constraint operators use left and right precedence values to determine whether the top operator on the stack should be reduced before pushing a new operator.
- ConstraintResult
Contains the result of matching a Constraint against an actual value.
- ContainsConstraint
ContainsConstraint tests a whether a string contains a substring or a collection contains an object. It postpones the decision of which test to use until the type of the actual argument is known. This allows testing whether a string is contained in a collection or as a substring of another string using the same syntax.

- PropertyConstraint
PropertyConstraint extracts a named property and uses its value as the actual value for a chained constraint.
- PropertyExistsConstraint
PropertyExistsConstraint tests that a named property exists on the object provided through Match.
