Remarks
DeleteField removes the specified field from a table, object class or feature class. Fields that are required by the Geodatabase and cannot be removed include:
- OBJECTID field
- SHAPE and shape dependent fields such as SHAPE_Length
- Enabled, AncillaryRole and Weight field for network feature classes
- subtype fields. In order to delete a subtype field, it must first be removed as the subtype field, see the help on ISubtypes::SubtypeFieldName
The following sample code demonstrates one methodology for deleting a field using DeleteField
'Assume we have a reference to a feature class, pFC
Dim pFields As IFields
Dim pField As IField
Set pFields = pFC.Fields
Set pField = pFields.Field(pFields.FindField("MyField"))
pFC.DeleteField pField
