How can I get all variable objects from the lua file in c# ?

[sillsun]

if I have a lua file which has numbles of variables ( string / number / table / function etc.. )
How can I get all luatables (string / numbers /etc .. )from the lua file without using the fullpath of the variables ?
Becasuse I do not have the path of the variables , so I can't use the method Lua.GetTable( fullpath ) to get them.
Is there any way that I can get all fullpath of the variables or all luabase type objects?
