RuleWriteAttribute Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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.

[AttributeUsageAttribute(AttributeTargets.Method | AttributeTargets.Property, 
	AllowMultiple = true)]
public sealed class RuleWriteAttribute : RuleReadWriteAttribute


Initializes a new instance of the RuleWriteAttribute class.

System_CAPS_pubmethodRuleWriteAttribute(String, RuleAttributeTarget)

Initializes a new instance of the RuleWriteAttribute class.


Gets the path to the target of the attribute.(Inherited from RuleReadWriteAttribute.)


Gets the RuleAttributeTarget enumeration value that determines how to use path to find target.(Inherited from RuleReadWriteAttribute.)


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

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.
