WorkflowChanges Class
Represents a set of proposed changes to a running workflow instance.
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
The WorkflowChanges type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | TransientWorkflow | Returns a cloned activity tree to which changes can be made and then applied to the running workflow instance. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetCondition | Gets the condition property on a dependency object. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | SetCondition | Sets the condition property on a dependency object. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | Validate | Validates the current set of proposed changes that have been made to the activity tree represented by the TransientWorkflow property. |
| Name | Description | |
|---|---|---|
![]() ![]() | ConditionProperty | Specifies the condition that must be satisfied to apply the WorkflowChanges. |
All proposed changes to a running workflow instance must be made using a WorkflowChanges object.
When a WorkflowChanges object is constructed in application code (outside the workflow instance), the Activity object that is passed to the constructor must be the object that is returned by the GetWorkflowDefinition method of the WorkflowInstance class.
The following example demonstrates creating a new instance of a WorkflowChanges object. This example is from the Ordering State Machine SDK sample. For more information, see Ordering State Machine Sample.
