DynamicActivity<TResult> Class

.NET Framework 4

Provides an approach that is consistent with the document object model (DOM), which constructs activities dynamically that interface with the WF designer and workflow runtime using ICustomTypeDescriptor.

System.Object
  System.Activities.Activity
    System.Activities.ActivityWithResult
      System.Activities.Activity<TResult>
        System.Activities.DynamicActivity<TResult>

Namespace:  System.Activities
Assembly:  System.Activities (in System.Activities.dll)
C#
C++
F#
VB
Copy 
[ContentPropertyAttribute("Implementation")]
public sealed class DynamicActivity<TResult> : Activity<TResult>, 
	ICustomTypeDescriptor

Type Parameters

TResult

The result returned by the activity.

The DynamicActivity<TResult> type exposes the following members.

  Name Description
Public method DynamicActivity<TResult> Creates a new instance of the DynamicActivity<TResult> class.
Top
  Name Description
Public property Attributes Gets the collection of attributes of the dynamically generated activity.
Protected property CacheId Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity.)
Public property Constraints Returns a collection of Constraint activities that are configured to provide validation for the DynamicActivity<TResult>.
Public property DisplayName Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from Activity.)
Public property Id Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity.)
Public property Implementation Gets or sets the execution logic of the activity.
Public property Name Gets the name to be displayed for the activity in the workflow designer.
Public property Properties Gets the collection of properties that map to the arguments of the dynamically generated activity.
Public property Result Gets or sets the result argument for the Activity<TResult>. (Inherited from Activity<TResult>.)
Public property ResultType When implemented in a derived class, gets the type of an activity OutArgument. (Inherited from ActivityWithResult.)

  Name Description
Protected method CacheMetadata Creates and validates a description of the activity’s arguments, variables, child activities, and activity delegates. (Inherited from Activity.)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ShouldSerializeDisplayName Indicates whether the DisplayName property should be serialized. (Inherited from Activity.)
Public method ToString Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity.)

Explicit interface implemetation Private method ICustomTypeDescriptor.GetConverter Returns a type converter for the dynamic activity.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetDefaultEvent Returns the default event for the dynamic activity.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetDefaultProperty Returns the default property for the dynamic activity.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetEditor Returns an editor with the specified base type.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetEvents() Returns the collection of events of the dynamic activity.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetEvents(Attribute[]) Returns the collection of events of the dynamic activity using a specified array of attributes as a filter.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetProperties() Returns the collection of properties of the dynamic activity.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetProperties(Attribute[]) Returns the collection of properties of the dynamic activity using a specified array of attributes as a filter.
Explicit interface implemetation Private method ICustomTypeDescriptor.GetPropertyOwner Returns this instance of the DynamicActivity<TResult> class.

With DynamicActivity<TResult> you can create new activities without creating new types. DynamicActivity<TResult> with its associated XAML support in ActivityXamlServices allows new arguments to be defined in XAML and bound by the host without requiring XAML to be compiled.
