If you pass a variable to a fortran function/classes.doc.html#374....
Call-by-name is supported by algol 68.
I don't know of any pass by fortran.
I think C Macros are Pass-by-name ( not the C language itself of course).

Well, the title says it all. When passing a file name to a method, should I use a FileInfo object or a plain file name (string)? Why would I prefer one to the other?

The difference.
However, you could overload the method to make everyone happy .
Typically I would pass the string.

If you want to get the class name of an object ....
$class_name = get_class($object);
__ CLASS __ with return the name of the class the method is implemented in.
See get_class , that should be exactly what you're trying to achieve .

I have a C# method that takes a string as an argument, that string contains the name of a static method e.g
"MyClass.GetData"
Is it possible to run that method from the value passed in the string?

From that, you can use the Invoke = method_full_path.Split('.'); string class_full_name = String.Format("{0}.{1}", tokens[0], tokens[1]); var class_blueprint = Assembly.GetExecutingAssembly....
That would return to you a MethodInfo class.
Is the string name.

In your Main function that has a parameter of string[] args .
Look at the command line arguments passed to your application at start up.
They should be passed by windows.
