Hello,

please find attached a very simple test of generics. I would like to limit the actual type in this list to be a child class of TObject. Is this possible and if yes, how can it be done?

In a more general question, what are the differences between the FPC generics and the C# generics (the ones used by the newer versions of Delphi)? In addition to the syntax, of course?

Best regards,
Thierry

I don't think it's currently supported. It will be, if someone is willing to do it.

To the best of my knowledge, FPC generics are based on C++ one, while C# one seems to be coming from Java. FPC one is simply hold as a macro by the compiler when it's declared and written with all generic types resolved when it's specialized. It's all done at compile time. In C# case, it's the runtime environment who is responsible for this. That's why C# one is more dynamic.
