Provides access to tracking data maintained in a SQL database by the SqlTrackingService for a workflow instance.
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The SqlTrackingWorkflowInstance type exposes the following members.
| Name | Description | |
|---|---|---|
.gif) | ActivityEvents | Gets the list of activity tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| AutoRefresh | Gets or sets a value that specifies whether property data for this SqlTrackingWorkflowInstance should be automatically updated when it is accessed. |
| Initialized | Gets or sets a DateTime that indicates the time at which the first TrackingChannel for this workflow instance was requested by the workflow run-time engine. |
| InvokedWorkflows | Gets a list of SqlTrackingWorkflowInstance objects that correspond to workflows that have been invoked by this workflow. |
| InvokingWorkflowInstanceId | Gets or sets the Guid of the workflow instance that invoked this workflow instance. |
| Status | Gets the status of the workflow instance. |
| UserEvents | Gets the list of user tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| WorkflowDefinition | Gets an Activity that represents the current workflow definition for the workflow instance. |
| WorkflowDefinitionUpdated | Gets a value that indicates whether the workflow has been updated since the last time WorkflowDefinition was loaded. |
| WorkflowEvents | Gets the list of workflow tracking records that have been sent for this workflow instance to a SqlTrackingService database by the run-time tracking infrastructure. |
| WorkflowInstanceId | The Guid of the workflow instance for which this SqlTrackingWorkflowInstance applies. |
| WorkflowInstanceInternalId | Gets or sets a number that can be used to find related records in separate views for this workflow instance. |
| WorkflowType | Gets and sets the Type of the workflow instance. |
| Name | Description | |
|---|---|---|
.gif) | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
.gif) | 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.) |
| Refresh | Updates the property data for this SqlTrackingWorkflowInstance. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
SqlTrackingWorkflowInstance objects are returned by a call to both SqlTrackingQuery
The following code example shows how to obtain information about all SqlTrackingWorkflowInstance objects contained in a list of displayed workflows. The code creates a ListViewItem for each SqlTrackingWorkflowInstance found in a displayedWorkflows variable. Each ListViewItem contains a string representation of the WorkflowInstanceInternalId, the WorkflowType and Status properties. It then adds the item to a workflowStatusList. The code uses the previously named property values and a string version of the Initialized property to create a new WorkflowStatusInfo object that is also added to the workflowStatusList.
This code example is part of the Workflow Monitor SDK Sample from the Mainform.cs file. For more information, seeWorkflow Monitor.
