Get the history "text" of a past work item edit

Say I make a work item in TFS. Then I make a change and update the text in the History tab (then save).

Using the TFS API, how can I get that text?

I would have thought it would have been in the History string for last item in the Revisions collection on the wo开发者_高级运维rk item. (Because to set the string via the API you can use History on a normal work item.) However, in the Revisions array, all the work items are showing up as having History empty.

Any ideas on how I can get this string?

It’s a simple operation, but it might not be clear at first unless you discover that you need to loop through the collection of Revisions of the work item in order to view those comments.

You can get any of the basic tfs fields via aaronbjork's link and change it to use

Field f = r.Fields.TryGetById(1); or Field f = r.Fields["Title"]

• title = 1
• description = 52
• the list of names and Ids is in the CoreField enumeration (only for non-custom fields)
