Example below is not working, but it illustrates what I want to get  
I know that templates are not supported for UClass, but I’m searching for some version of cast which accepts uclass as a function parameter or any other workaround

```
class Foo {
    FString Name;
}

TSubClass<Foo> Bar;
TArray<Foo> arr;

FString Name = Cast<Bar.Get()>( arr[i] ).Name;

```

For this to work, wouldn’t class Foo need to look like this?

```
UCLASS()
class Foo {
   GENERATED_BODY()

   FString Name;
}
```

Thats not possible, C++ types only exist in compile time and it’s only used to construct machine code, they are not dynamic in anyway. Same goes with templates.

Also i don’t really understand why you want to do this looking on the code, you expect type Foo to have a property Name… why you casting it then?

You might also look in to interfaces which solves lot of class relation problems
