The Constraint type exposes the following members.
| Name | Description | |
|---|---|---|
 | CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity.) |
| CanInduceIdle | Gets or sets a value that indicates whether the activity can cause the workflow to become idle. (Inherited from NativeActivity.) |
| Constraints | Gets a collection of Constraint activities that can be configured to provide validation for the Activity. (Inherited from Activity.) |
| DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from Activity.) |
| Id | Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity.) |
| Implementation | The execution logic of the activity. (Inherited from NativeActivity.) |
| ImplementationVersion | Gets or sets the implementation version of the activity. (Inherited from NativeActivity.) |
| Name | Description | |
|---|---|---|
| Abort | When implemented in a derived class, takes actions in response to the activity being aborted. (Inherited from NativeActivity.) |
| AddValidationError | Adds a validation error to a list of run-time validation errors that are attached to the execution context. |
| CacheMetadata(ActivityMetadata) | Not implemented. Use the CacheMetadata method instead. (Inherited from NativeActivity.) |
| CacheMetadata(NativeActivityMetadata) | Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process. (Overrides NativeActivity.CacheMetadata(NativeActivityMetadata).) |
| Cancel | When implemented in a derived class, runs logic to cause graceful early completion of the activity. (Inherited from NativeActivity.) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Execute | Invokes the process that validates an activity. (Overrides NativeActivity.Execute(NativeActivityContext).) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from 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.) |
| OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity) | Raises an event when creating a map for the dynamic update. (Inherited from NativeActivity.) |
| OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity) | Raises an event when creating a map for the dynamic update. (Inherited from NativeActivity.) |
| OnExecute | When implemented by a derived class, validates the specified object using the specified native activity and validation contexts. |
| ShouldSerializeDisplayName | Indicates whether the DisplayName property should be serialized. (Inherited from Activity.) |
| ToString | Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity.) |
| UpdateInstance | Updates the instance of NativeActivity. (Inherited from NativeActivity.) |
| Name | Description | |
|---|---|---|
| ValidationErrorListPropertyName | The name for an activity constraint property that is a list of workflow run-time validation errors. |
