Datetime and day of week

Question

Write a program, which prints, on the console which day of the week is today

 

 1. //DayOfWeek now = DateTime.Today.DayOfWeek;

//Console.WriteLine(now);

2. DateTime today = DateTime.Today;

string date=today.DayOfWeek;

Console.WriteLine(today);

 

Questions are : 

 

A) With the first code i am getting the value....but with the second i am not getting. I want to know how we can do from 2nd one...

 

B) Also we have DATETIME and DAYOFWEEK. which one should we use while using IDE?

 

C) Also i get confused should we use brackets at the end or not ? in what cases should we use brackets .

For example if i give DayOfWeek now = DateTime.Today.DayOfWeek(); it gives me error.

But if i give DayOfWeek now = DateTime.Today.DayOfWeek; it works. What is the concept here? Pls suggest
