If DateTime is immutable, why does the following work?

Question

I thought I understood what Immutable meant, however I don\'t understand why the following compiles and works:

DateTime dt = DateTime.Now;

Console.WriteLine         


        

Answer 1

The Now property is something like:

 DateTime Now {
     get {
         // Get the OS time
         return new DateTime(year, month, day, hour, min, sec...)
     }
 }

(technically false, the Now calls internally the UtcNow that calls the OS :-), but you get the idea).

The DateTime.Now is a factory for DateTime :-)
