How can I set a fieldflag in VNET

[Carsten Ilwig]

Hi,
how can I set a fieldflag in Valentina.NET?
For Example the unique-flag for a field that can only contain unique values,
or for an field which is an methodefield?
In V4MD there are the methodes SetFieldFlag() and GetFieldFlag. Where can I
find such methodes in VNET?

Thanks for your answer.
Carsten
