Create field of type Business data with the object model

Question

How can I create a Business Data catalog field with the object model? So I want to create a field that utilities business data catalog and not add an item to an already existing list.

Answer 1

You will have to be a bit more precise. BDC fields are used in many places and can be defined in many ways: application definitions, user profiles, lists, lobsystems in web parts etc.

below is an example on how to instantiate a BDC field in an SPList, as this is something that usually causes a bit of trouble:

SPListItem item = someList.Items.Add();

// assign fields
..
item["MyProductID"] = EntityInstanceIdEncoder.EncodeEntityInstanceId(new object[]{"1234"}); // this could also be an integer 
..
item.Update();// alternatively use SystemUpdate
