プロパティ値
型: System.Boolean
Returns Booleantrue if the field derives from a base field type; otherwise, returns false.
注釈
The base field types are defined in FLDTYPES.XML, which defines the default schema for lists. Every built-in list in a site inherits its schema from a base type. If the FromBaseType property returns true, the field cannot be converted to another field type, nor can it be deleted.
ヒント
If you want to prevent a field from being modified or deleted, set the Sealed property to true.
