public function TFields.FieldByName(

const Value: string

):TField;

Fieldname to search for

Function result

Field instance with FieldName matching Value

Description

Fieldbyname searches the list of fields and returns the field instance whose FieldName property matches Value. The search is performed case-insensitively.

Errors

If no field instance is found, then an exception is raised. If this behaviour is undesired, use TField.FindField, where Nil is returned if no match is found.
