TFieldsEnumerator implements all the methods of IEnumerator so a TFields instance can be used in a for..in construct. TFieldsEnumerator returns all the fields in the TFields collection. Therefor the following construct is possible:
Var F : TField; begin // ... For F in MyDataset.Fields do begin // F is of type TField. end; // ...
Do not create an instance of TFieldsEnumerator manually. The compiler will do all that is needed when it encounters the for..in construct.
