ActivityCondition Class

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 |
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) |
