此 API 现已过时。

当持久性服务无法满足请求时引发的异常。The exception that is thrown when the persistence service cannot fulfill a request.

备注

本材料讨论的类型和命名空间已废弃不用。This material discusses types and namespaces that are obsolete. 有关详细信息,请参阅 Windows Workflow Foundation 4.5 中弃用的类型For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

SqlWorkflowPersistenceService 因无法完成请求而不能向其数据库提交完整的范围或工作流实例状态时,将引发 PersistenceExceptionThe SqlWorkflowPersistenceService throws a PersistenceException if it cannot complete a request to commit either a completed scope or the workflow instance state to its database.

如果通过从 WorkflowPersistenceService 类或 SqlWorkflowPersistenceService 类派生来实现持久性服务,则可以引发 PersistenceException 并显示一条适当的消息,用于指示您的服务所遇到的任何错误条件,这些错误条件会阻止服务完成由工作流运行时引擎发出的请求。If you implement a persistence service by deriving from the WorkflowPersistenceService class or the SqlWorkflowPersistenceService class, you can throw the PersistenceException with an appropriate message to indicate any error condition encountered by your service that prevents it from fulfilling a request made by the workflow runtime engine.

有关更多信息,请参见 WorkflowPersistenceService 类。See the WorkflowPersistenceService class for more information.
