Get workflow associated list items

Question

I have one requirement to get all the list items which has associated with a particular workflow in SharePoint 2013. Like, I have a designer 2013 workflow with name "Test Workflow" which is added in a custom list. Tis workflow associated with around 70 items. In the same list I've added another workflow with name "Test Workflow 2". I need to fetch the ID of all the list items which are associated with the first workflow (all the 70 items ID).

Answer 1

I suppose a query can be built filtering

taskItem["WorkflowListId"]
taskItem["WorkflowItemId"]
