WorkflowMarkupSerializer Class

Provides the extensible Application Markup Language (XAML) serialization services to workflows at design time.

Namespace:  System.Workflow.ComponentModel.Serialization
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

public class WorkflowMarkupSerializer

The WorkflowMarkupSerializer type exposes the following members.

Public methodWorkflowMarkupSerializerInitializes a new instance of the WorkflowMarkupSerializer class.

Protected methodAddChildAdds a child object to the specified object.
Protected methodCanSerializeToStringReturns a Boolean that indicates whether the specified object can be serialized to a string.
Protected methodClearChildrenRemoves all child objects from the specified object.
Protected methodCreateInstanceCreates an instance of the specified Type using the specified WorkflowMarkupSerializationManager.
Public methodDeserialize(XmlReader)Deserializes workflow markup into an Object.
Public methodDeserialize(IDesignerSerializationManager, XmlReader)Deserializes workflow markup into an Object using the specified serialization manager.
Protected methodDeserializeFromStringDeserializes extensible Application Markup Language (XAML) content from the specified string according to the given type of the property to deserialize.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Protected methodGetChildrenRetrieves a list of child objects for the specified object
Protected methodGetEventsRetrieves information about all events associated with the specified Object.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Protected methodGetPropertiesRetrieves information about all properties associated with the specified object.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnAfterDeserializeOverridden. Notifies the WorkflowMarkupSerializer that an object has just been deserialized.
Protected methodOnAfterSerializeNotifies the WorkflowMarkupSerializer that an object has just been serialized.
Protected methodOnBeforeDeserializeOverridden. Notifies the WorkflowMarkupSerializer that an object is about to be deserialized.
Protected methodOnBeforeSerializeNotifies the WorkflowMarkupSerializer that Serialize is about to run.
Public methodSerialize(XmlWriter, Object)Serializes the specified Object into a workflow markup file or stream.
Public methodSerialize(IDesignerSerializationManager, XmlWriter, Object)Serializes the specified Object into a workflow markup file or stream using the specified serialization manager.
Protected methodSerializeToStringSerializes the specified Object to a string.
Protected methodShouldSerializeValueReturns a value that indicates whether the WorkflowMarkupSerializer should serialize the specified Object.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public fieldStatic memberClrNamespacesPropertyRepresents an attached DependencyProperty that is used to define which assemblies to reference for custom activities.
Public fieldStatic memberEventsPropertyRepresents an attached DependencyProperty that defines the names for event handler properties.
Public fieldStatic memberXClassPropertyRepresents an attached DependencyProperty that defines the type name, which will be created during compilation.
Public fieldStatic memberXCodePropertyRepresents a code example, embedded into XAML x:Code element.

WorkflowMarkupSerializer provides methods that serialize workflow and Activity classes into XAML format and deserialize XAML content into workflow and activity class objects. These services are primarily used by workflow designers to persist the classes on the workflow design surface.

WorkflowMarkupSerializer is the base class for all markup serializers included in the System.Workflow.ComponentModel.Serialization namespace.

For more information, see Serialization.

WorkflowMarkupSerializer does not support serialization of nested types.

The functionality of WorkflowMarkupSerializer is dependent on functionality of other types outside of Windows Workflow Foundation. Based on the limitations of those other types, not all data types can be serialized through the WorkflowMarkupSerializer. The following is a list is an example of some unsupported types.


This is not an exhaustive and complete list of unsupported types.

Arrays (supported only if property is not decorated with DesignerSerializationVisibility.Content attribute value)

Types without parameterless constructors

Multidimensional Arrays

Generic types (Generic List and Dictionary types supported only if property is decorated with DesignerSerializationVisibility.Content attribute value)







Enumeration Arrays

Enumerations decorated with the FlagsAttribute

In addition to this list, any property decorated with both the ContentPropertyAttibute and the DesignerSerializationVisibilityAttribute cannot be serialized by WorkflowMarkupSerializer.

.NET Framework

Supported in: 4, 3.5, 3.0

Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
