Getting all Symbols from Family in Revit 2018

[WorldDue]

Seems to me that the property Symbols is not there in Revit API 2018, Is there any alternative method to get all the Symbols in a Family, also is it me or the Cast<T>() is also deleted?

Ignore the Cast<T> question, it's a Linq extended function.

• Open the Revit API documentation.
• Look at the Family member methods.
• Discover the GetFamilySymbolIds method:

Alternatively, read the Revit API What's New documents:

Family.Symbols

The property Family.Symbols has been obsoleted – use

• Family.GetFamilySymbolIds()

as a replacement.
