Question

I have a method, accepting a Hashtable (yes I know, it’s outdated..) as argument:

public static LuaTable HashtableToLuatable(Hashtable t, int depth = 1)

This works correctly.

Now I’d like to accept an ArrayList as first parameter as well, so you can let ‘t’ have the value of both a Hashtable and an ArrayList. Currently I have copy-pasted the method two times, like this:

public static LuaTable ArraylistToLuatable(ArrayList t, int depth = 1)

The rest is exactly the same.

I think there’s a way to merge this.

Answer 1

Both classes implement the ICollection interface, so if your ‘common code’ will work against the definition of the ICollection interface, you could use that for your parameter type.
