`System.Activities.Statements.Throw`

Throws a specified exception. **Throw** signals an error condition at a point in the workflow. The exception propagates up the call stack until it is handled by a surrounding [Try Catch](https://docs.uipath.com/activities/other/latest/workflow/try-catch) activity, or — if uncaught — terminates the workflow.
