Interop Class
An activity that manages the execution of an System.Workflow.ComponentModel::Activity within a workflow.
System.Activities::Activity
System.Activities::NativeActivity
System.Activities.Statements::Interop
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The Interop type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ActivityMetaProperties | The collection of name-value pairs that corresponds to the metadata of the System.Workflow.ComponentModel::Activity, such as an activity’s Name property, or a WhileActivity activity’s Condition() property. |
![]() | ActivityProperties | Gets the collection of name-value pairs that corresponds to the input and output properties of the System.Workflow.ComponentModel::Activity. |
![]() | ActivityType | Gets or sets the type of the activity contained by the Interop activity. |
![]() | 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.) |
| Name | Description | |
|---|---|---|
![]() | Abort | When implemented in a derived class, takes actions in response to the activity being aborted. (Inherited from NativeActivity.) |
![]() | CacheMetadata(ActivityMetadata) | Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead. (Inherited from NativeActivity.) |
![]() | CacheMetadata(NativeActivityMetadata) | Creates and validates a description of the activity’s arguments, variables, child activities, and activity delegates. (Inherited from NativeActivity.) |
![]() | 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 | When implemented in a derived class, runs the activity’s execution logic. (Inherited from NativeActivity.) |
![]() | 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.) |
![]() | 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.) |
Note |
|---|
The Interop activity will not appear in the workflow designer toolbox unless the workflow's project has its Target Framework setting set to .Net Framework 4. |
Caution |
|---|
Due to limitations in the interface types that the Interop activity can support, HandleExternalEventActivity and CallExternalMethodActivity cannot be used directly, but derivative activities created using the Workflow Communication Activity tool (WCA.exe) can be used. See Windows Workflow Foundation Tools for details. |
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.
