How can i make and call a method without any paramaters?

Question

I want to simply call my method like this: collect.clear; instead of, collect.clear();

in other words, I want to make this method

    class collect
    {
       public List<string> list = new List<string>();
       public void Clear()
       {
           list.clear();
       }
    }

to be called like so

    static void Main(string[] args)
    {
        collect.clear;
    }

is this possible or not at all.

No you can't do that. You must write `()` when calling a method, otherwise it's a method group. — Sweeper, Dec 10 '19 at 17:22
the methods aren't set up entirely correctly I was in a hurry sorry. — TyperMan1133, Dec 10 '19 at 17:22
@Train where can I find documentation of these smart getter\setters? — TyperMan1133, Dec 10 '19 at 17:38

Well, frankly: you don't get to decide what the language syntax is, and in C#, the syntax for invoking a method is: collect.clear();.

Basically, you can't do what you want. You could make it a property, but then you'd need to discard the result (so it can choose between get and set), i.e. with a property get called clear, _ = collect.clear; - frankly I think that's a step back from the (). It is also a terrible idea from the basis of unexpected side-effects; most UI elements (including the debugger) and libraries (serializers, etc) think that they can freely evaluate property gets, so it would be very unexpected it reviewing a property had the side effect of clearing the data! Basically, don't do that.

So; embrace the (). They express the intent here, for your benefit, the benefit of people reviewing/maintaining it, and for the benefit of the compiler.
