Code special to MVC
-
Saw this in an example when setting properties. Is this some kind of special ASP.NET MVC syntax?
var movie = new Movie() {
Name = "Shrek!"
};Where Name is a property of the class Movie.
No, there's no such thing as a "special syntax for ASP.NET MVC". That's standard C# syntax that's been around since VS2008.

Dave KreskowiakRead this. Seriously, do it. "If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome" "Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid"

Read Dave's response again. He didn't insult you; he just answered your question - and correctly at that. :doh:

Further to Dave's answer, see: Object and Collection Initializers (C# Programming Guide)[^] How to: Initialize Objects by Using an Object Initializer (C# Programming Guide)[^] Since you're not passing any constructor parameters, you don't even need the empty parentheses after the type name:
var movie = new Movie {
Name = "Shrek!"
};

Ummm... what's wrong with you? How on this planet did I insult you?

I think adding the "Seriously, do it" was unnecessary, like I was some idiot. You could have only said "please read this" or something.

Lighten up, Francis. I hate to tell you this, but that's part of my signature. It shows up on everything I post here. Why do I have that link in there? Because over the 13 years I've been around here I've watched the quality of questions plummet. There are so many "questions" asked around here that don't qualify as questions at all and usually don't have any context to frame the question nor enough detail to answer them. Asking questions really is a skill. As you are/were a teacher: Hi! I am a teaches a course in C# for beginners. you should already know this.

As I said I misunderstood. It was the signature, not aimed at me. Yes, he did answer my question and thanks for the further clarification.

Hm, so when do you use this? Feels like everything I thought my students about private variables and getters and setters is obsolete... Here´s something to put in my signature. The more I learn the more I realize how little I know...
It doesn't replace the property stuff at all. In fact, this syntax uses those properties. The syntax change is just "shortcut sugar" to avoid having to new up the type and then add a bunch of code to set the properties in multiple statements.

It's just syntactic sugar designed to reduce the amount of code you type. It doesn't render any of your previous knowledge obsolete, it's just that it's easier to read something like this:
Movie movie = new Movie
{
Name = "Batman vs Superman",
ReleaseYear = 2016,
Rating = 4.5
}Than it is to read this:
Movie movie = new Movie();
movie.Name = "Batman vs Superman";
movie.ReleaseYear = 2016;
movie.Rating = 4.5;It also means you don't have to provide multiple overloaded constructors if you're just providing properties that you want to populate. I don't want to blow your mind, but you can extend this concept to also include collection initialisation as well. Suppose you added a list of actors to your class, you can initialise it like this:
Movie movie = new Movie
{
Name = "Batman vs Superman",
ReleaseYear = 2016,
Rating = 4.5,
Actors = new List<string> { "Ben Afleck", "Jessie Eisenberg", "Gal Gadot", "Henry Cavill" }

No; It's already available in c# language called as object initializer. for eg :- Student objstd=new Student(){ Name ="Surya", roll=112, Adress="Hyd" }; So it's available in net framework version 3.0 on word.
