when we can inherit from base class / interface, why can't we declare a List<> using same classes / interface interface A { } class B : A { } class C : B { } class Test { static void Main(string[] args) { A a = new C(); // OK List<A> listOfA = new List<C>(); // compile...

I'm trying to write a function that reads files from a "deferred" directory which contains files that contain lists. Here's what the files in the deferred folder contain: '173378981', '45000', '343434', '3453453', '34534545', '3452342', '234234', '42063008', 'Exempted', '10000' '1000014833', '0', '0', '0', '0', '0', '0', '0', 'Exempted'...

Is there a way to pass a list as a function argument to eval() Or do I have to convert it to a string and then parse it as a list in the function? My simple example looks like: eval("func1(\'" + fArgs + "\')") I'm just not sure if there is a better way of taking fArgs as a list instead of a string Note: The list is provided from a ...
I do next: void Foobar(string[] arr, Dictionary<string, string[]>) { var t = arr.Intersect(dic.Keys).ToList(); // .or ToArray() ? foreach(var item in t) { .. } var j = t.Count; // also I need this } which method is preferred?

This is what I normally do in order to ascertain that the input is a list/tuple - but not a str. Because many times I stumbled upon bugs where a function passes a str object by mistake, and the target function does for x in lst assuming that lst is actually a list or tuple. assert isinstance(lst, (list, tuple)) My question is: is ther...
