Esri Fields object.
|IClone (esriSystem)||Provides access to members that control cloning of objects.|
|IFields||Provides access to members that return information about the fields.|
|IFields2||Provides access to members that return information about the fields.|
|IFieldsEdit||Provides access to members that modify a fields collection.|
|IPersist||Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile.|
|IXMLSerialize (esriSystem)||Provides access to members that XML serialize and deserialize an object to/from XML.|
Each table in a database has an ordered collection of fields, there is always at least one field in a table. The ordered collection behaves like a list, so it is possible to access individual fields by a numbered position (or index) in the list.
A Fields collection can also exist independently of a table, for example when creating an index on a table you will need to define which fields take part in the index. There are many interfaces which either require or return a Fields collection; these include IClass (therefore also IObjectClass and IFeatureClass), ICursor, IIndex, IFeatureClassDraw, IRowBuffer, ISimpleDataConverter, ITableSort and IValidate.
