ActivityCondition Class

Definition

Namespace:

System.Workflow.ComponentModel

Assembly:

System.Workflow.ComponentModel.dll

Caution

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

Represents an abstract class for an expression, which evaluates to a Boolean. This class must be inherited.

Remarks

Note

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

A condition is an expression, which evaluates to a Boolean value.

Windows Workflow Foundation offers two condition types: CodeCondition and RuleConditionReference.

You can create a custom condition type by deriving from this class and implementing the Evaluate method.

Constructors

ActivityCondition()

When implemented in a derived class, initializes a new instance of the ActivityCondition class.

Properties

DesignMode	Gets the value that indicates whether this instance is in design or run-time mode. (Inherited from DependencyObject)
ParentDependencyObject	Gets the parent DependencyObject in the DependencyObject graph. (Inherited from DependencyObject)
Site	Gets or sets a reference to the Site component of the DependencyObject. (Inherited from DependencyObject)
UserData	Gets an IDictionary that associates custom data with this class instance. (Inherited from DependencyObject)

Methods

AddHandler(DependencyProperty, Object)	Adds a handler for an event of a DependencyObject. (Inherited from DependencyObject)
Dispose()	Releases all the resources used by the DependencyObject. (Inherited from DependencyObject)
Dispose(Boolean)	Releases the unmanaged resources and optionally releases the managed resources used by DependencyObject. (Inherited from DependencyObject)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Evaluate(Activity, IServiceProvider)	Evaluates the underlying condition.
GetBinding(DependencyProperty)	Provides access to the ActivityBind associated with the specific DependencyProperty. (Inherited from DependencyObject)
GetBoundValue(ActivityBind, Type)	Retrieves the Object that is the subject of an ActivityBind. (Inherited from DependencyObject)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetInvocationList<T>(DependencyProperty)	Gets an array that contains the delegates for the specified DependencyProperty. (Inherited from DependencyObject)
GetType()	Gets the Type of the current instance. (Inherited from Object)
GetValue(DependencyProperty)	Provides access to the value of the designated DependencyProperty. (Inherited from DependencyObject)
GetValueBase(DependencyProperty)	Provides access to the bound object of a DependencyProperty and bypasses the GetValue(DependencyProperty) override. (Inherited from DependencyObject)
InitializeProperties()	Performs initialization on dependency properties when overridden in a derived class. (Inherited from DependencyObject)
IsBindingSet(DependencyProperty)	Indicates whether the value of a DependencyProperty is set as a binding. See SetBinding(DependencyProperty, ActivityBind). (Inherited from DependencyObject)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
MetaEquals(DependencyObject)	Determines whether the metaproperties of this DependencyObject equals the metaproperties of the parameterized DependencyObject. (Inherited from DependencyObject)
RemoveHandler(DependencyProperty, Object)	Removes an EventHandler from an associated DependencyProperty. (Inherited from DependencyObject)
RemoveProperty(DependencyProperty)	Removes a DependencyProperty from the DependencyObject. (Inherited from DependencyObject)
SetBinding(DependencyProperty, ActivityBind)	Sets the ActivityBind for the specified DependencyProperty. (Inherited from DependencyObject)
SetBoundValue(ActivityBind, Object)	Sets the value of the target ActivityBind. (Inherited from DependencyObject)
SetReadOnlyPropertyValue(DependencyProperty, Object)	Sets the value of a DependencyProperty, which is read-only. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the value of the DependencyProperty to the object. (Inherited from DependencyObject)
SetValueBase(DependencyProperty, Object)	Sets the value of the DependencyProperty to the specified Object, bypassing the SetValue(DependencyProperty, Object). (Inherited from DependencyObject)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

IComponent.Disposed

Represents the method that handles the Disposed event of a component. (Inherited from DependencyObject)
