System.Workflow.Activities.Rules Namespace ()

.NET Framework Class Library

System.Workflow.Activities.Rules Namespace

Contains a set of classes that define the conditions and actions that form a rule.

Classes

	Class	Description
	AddedConditionAction	Represents the addition of a RuleCondition to a workflow during dynamic update. This class cannot be inherited.
	AddedRuleSetAction	Represents the addition of a RuleSet during dynamic update. This class cannot be inherited.
	RemovedConditionAction	Represents the removal of a RuleCondition from a workflow during dynamic update. This class cannot be inherited.
	RemovedRuleSetAction	Represents the removal of a RuleSet during dynamic update. This class cannot be inherited.
	Rule	Defines a condition with an associated set of actions to perform.
	RuleAction	Represents an abstract class that defines an action to be executed if the associated Condition evaluates to true, for ThenActions, or false, for ElseActions. This class must be inherited.
	RuleActionTrackingEvent	Contains the name, instance ID, and condition result of a rule that has been evaluated.
	RuleAnalysis	Stores the fields and properties read by a condition or written to by an action.
	RuleAttribute	Represents the base class for custom Rule attributes.
	RuleCondition	Base type for RuleExpressionCondition and any custom conditions created by users.
	RuleConditionChangeAction	Represents an abstract base class from which all dynamic update notifications of changes to RuleConditions must be derived.
	RuleConditionCollection	Contains a collection of RuleCondition classes defined on the workflow. This class cannot be inherited.
	RuleConditionReference	Represents a RuleCondition in the conditions collection and enables you to programmatically evaluate the condition.
	RuleDefinitions	Represents the root of the .rules files and contains all the RuleSets and RuleConditions associated with a workflow. This class cannot be inherited.
	RuleEngine	Used to perform RuleSet evaluation.
	RuleEvaluationException	Represents the base class for all exceptions caused by rule evaluation issues.
	RuleEvaluationIncompatibleTypesException	The exception that is thrown when attempting to apply an operator to incompatible operands when you evaluate a rule.
	RuleException	Represents the base class for all exceptions caused by evaluation or validation of rules.
	RuleExecution	Stores state information while executing RuleCondition or RuleAction classes.
	RuleExpressionCondition	Defines the condition definition behind a RuleConditionReference. This class cannot be inherited.
	RuleExpressionInfo	An instance of this class is returned by the Validate method of an IRuleExpression expression.
	RuleExpressionResult	Abstract class that is the base for classes representing the result of custom expressions based on the IRuleExpression interface.
	RuleExpressionWalker	Propagates the current behavior in the expression to child nodes. This class cannot be inherited.
	RuleHaltAction	Causes the RuleSet to stop executing and returns control back to the calling method.
	RuleInvokeAttribute	Indicates that a method is invoked by a condition. This class cannot be inherited.
	RuleLiteralResult	Represents the literal result of a custom expression written using IRuleExpression.
	RulePathQualifier	Builds the path of a field or property.
	RuleReadAttribute	Indicates that a property is read by a Rule. This class cannot be inherited.
	RuleReadWriteAttribute	Represents the base class for the RuleReadAttribute and RuleWriteAttribute classes.
	RuleSet	Contains a collection of Rule classes along with the semantics for forward-chaining execution of those rules. A RuleSet can be executed directly in code or using the PolicyActivity activity.
	RuleSetChangeAction	Represents an abstract base class from which all dynamic update notifications of changes to a RuleSet must be derived. This class cannot be inherited.
	RuleSetCollection	Contains a collection of RuleSet classes defined in a workflow.
	RuleSetReference	Holds the name of a RuleSet in the RuleSetCollection on the workflow. This class cannot be inherited.
	RuleSetValidationException	Represents the exception thrown when processing cannot continue because a rule set cannot be validated.
	RuleStatementAction	Specifies a property or field to update or a method to run using the CodeDom types.
	RuleUpdateAction	Indicates that a rule is updating a variable, in order to cause reevaluation of affected rules.
	RuleValidation	Validates expression conditions.
	RuleWriteAttribute	Indicates that a property or field is written by the method or property that this attribute is applied to. This information is used by the rules engine to determine dependencies between rules. This class cannot be inherited.
	UpdatedConditionAction	Represents the change to a RuleSet for dynamic updates. This class cannot be inherited.
	UpdatedRuleSetAction	Represents the change to a RuleSet for dynamic updates. This class cannot be inherited.

Interfaces

	Interface	Description
	IRuleExpression	Represents the base class from which custom expression writers must derive to write custom expressions.

Enumerations

	Enumeration	Description
	RuleAttributeTarget	Specifies whether the path in a RuleReadAttribute or RuleWriteAttribute is for a method parameter, or this.
	RuleChainingBehavior	Specifies the forward chaining behavior of the RuleSet.
	RuleReevaluationBehavior	Specifies whether a Rule can be reevaluated.
