Dim instance As SPField
Dim value As Boolean

public bool FromBaseType { get; }
Property Value
Type: System.Boolean
true if the field derives from a base field type; otherwise, false.

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 this property contains true, the field cannot be converted to another field type.
