The Expression namespace may be used by applications as a framework for building new kinds of ICriterion. However, it is intended that most applications will simply use the built-in criterion types via the static factory methods of this class.

The following tables list the members exposed by the Expression type.

Public Methods

	Name	Description
	AllEq	Apply an "equals" constraint to each property in the key set of a IDictionary
	And	Return the conjuction of two expressions
	Between	Apply a "between" constraint to the named property
	Conjunction	Group expressions together in a single conjunction (A and B and C...)
	Disjunction	Group expressions together in a single disjunction (A or B or C...)
	Eq	Apply an "equal" constraint to the named property
	EqProperty	Apply an "equal" constraint to two properties
	Ge	Apply a "greater than or equal" constraint to the named property
	GeProperty	Apply a "greater than or equal" constraint to two properties
	Gt	Apply a "greater than" constraint to the named property
	GtProperty	Apply a "greater than" constraint to two properties
	IdEq	Apply an "equal" constraint to the identifier property
	In	Overloaded.
	InG<(Of T>)	Apply an "in" constraint to the named property. This is the generic equivalent of In(String, ICollection), renamed to avoid ambiguity.
	InsensitiveLike	Overloaded.
	IsEmpty	Apply an "is not empty" constraint to the named property
	IsNotEmpty	Apply an "is not empty" constraint to the named property
	IsNotNull	Apply an "is not null" constraint to the named property
	IsNull	Apply an "is null" constraint to the named property
	Le	Apply a "less than or equal" constraint to the named property
	LeProperty	Apply a "less than or equal" constraint to two properties
	Like	Overloaded.
	Lt	Apply a "less than" constraint to the named property
	LtProperty	Apply a "less than" constraint to two properties
	Not	Return the negation of an expression
	NotEqProperty	Apply an "not equal" constraint to two properties
	Or	Return the disjuction of two expressions
	Sql	Overloaded.
