RuleWriteAttribute Class


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.

public ref class RuleWriteAttribute sealed : System::Workflow::Activities::Rules::RuleReadWriteAttribute
[System.AttributeUsage(System.AttributeTargets.Method | System.AttributeTargets.Property, AllowMultiple=true)]
public sealed class RuleWriteAttribute : System.Workflow.Activities.Rules.RuleReadWriteAttribute

Public NotInheritable Class RuleWriteAttribute
Inherits RuleReadWriteAttribute


This attribute is used to support a forward chaining model that causes the re-evaluation of rules based on changes to fields and properties. The RuleReadAttribute and RuleWriteAttribute indicate the properties read or written by the property or method the attribute is applied to. RuleInvokeAttributes are used to indicate that this property or method uses other methods, which must also be checked for dependencies.
