ArcObjects Library Reference (GeoDatabase)  

IFieldEdit Interface

Provides access to members that edit the field properties. Note: the IFieldEdit interface has been superseded byIFieldEdit2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The IFieldEdit interface is used when creating new fields. You should not use it to modify fields, for that purpose use IClassSchemaEdit. In general, when modifying fields, the restrictions that apply in ArcCatalog also apply in ArcObjects; for example, you cannot change the name or type of a field.
