Your problem is that you have a Length property in your class, so
that's why you need to use System.Length()
Yes
. Try something like this:
=== code begin ===
type
generic TMyHelper<T> = class
class function GetLength(aArray: specialize TArray<T>): LongInt;
end;
When I use:
generic TLengthHelper<T> = class
class function GetLength(A: specialize T2DArray<T>): Integer; //
<-- HERE I get error "Error: expected ;, but T2DArray found"
end;
Ok, I will leave "Length" and rename it to "Count" ;-)
Thanks
