Named arguments

Question

Am I right to assume that when you are declaring a method’s parameters you HAVE to give each parameter a name. Thus, ALL arguments are “named arguments”.

Answer 1

yes and also which type of data.

Answer 2

Well, "Named Parameters" are a feature of C# that can match a parameter passed in, with a name. Previously parameters could only be evaluated sequentially as they were declared. Example:
public int AddNumbers(int firstNum, int secondNum). To call this method, we would need to send a first number then a second number, AddNumbers(1,2), in the order we declared them. Using the named parameter feature we can pass them in any order but, we have to tell c# which parameter we are passing eg
AddNumbers(secondNum:2, firstNum:1).
