Namespace:  System.Workflow.Activities.Rules
Assembly:  System.Workflow.Activities (in System.Workflow.Activities.dll)

public class RuleUpdateAction : RuleAction

The RuleUpdateAction type exposes the following members.

Public methodRuleUpdateAction()Initializes a new instance of the RuleUpdateAction class.
Public methodRuleUpdateAction(String)Initializes a new instance of the RuleUpdateAction class.

Public propertyPathGets or sets the path of the RuleUpdateAction.

Public methodCloneCreates a deep copy of the current RuleAction. (Overrides RuleAction.Clone().)
Public methodEqualsDetermines whether two object instances are equal. (Overrides Object.Equals(Object).)
Public methodExecuteExecutes the RuleAction using the specified RuleExecution. (Overrides RuleAction.Execute(RuleExecution).)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Overrides Object.GetHashCode().)
Public methodGetSideEffectsReturns the fields and properties updated by a RuleAction. (Overrides RuleAction.GetSideEffects(RuleValidation).)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that indicates the field or property that the Rule is updating. (Overrides Object.ToString().)
Public methodValidateVerifies that the RuleAction is configured correctly and has no errors. (Overrides RuleAction.Validate(RuleValidation).)

This class is used to indicate to the rules engine that execution of this rule's set of actions causes a change to the field or property that is specified (or all fields and properties on an object), so that any rules that are dependent on this field or property can be reevaluated.

An Update call does not prevent other actions in the action block from executing. The set of fields/properties that are modified (specified through Update or by using RuleWriteAttributes on methods invoked) is used to determine chaining when the set of actions for this particular rule finishes executing.
