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!"
};

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 Feels like everything I thought my students about private variables and getters and setters is obsolete...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.

Try posting the code that you are having problems with - it might help us understand your question

Dave Kreskowiak24-Jun-16 3:59

24-Jun-16 3:59

Ummm....WHAT??

"Present address"?? "permanent address"?? How does a checkbox relate to this?

You've failed to provide any context at all and now definitions for these terms. It's pretty much impossible to help you until you do.

You'll either need JavaScript to hook up the checkbox "checked" event with the copy operation on the client side; or check the value of the checkbox in the controller code on the server and do the copy there.

Generic Function for executing any parametric/non parametric function using C#

Through the magic of ViewModels!

public ActionResult DoMyThing(MyViewModel vm)
{
   if (vm.ChangeAddressFoo)
   {
      vm.PermanantAddress.CopyMethod(vm.PresentAddress);
      _context.MyRepoUpdateMethod(vm.PermanantAddress);
      return Json(new{Change = true})
   }
   return Json(new{Change = false})
}

Okay, you have a high level requirement. You are now going to need to break that down into lower level requirements and keep refining these requirements until you reach a point where you can come up with a design. Here are some things you might want to consider.

Do your stored procedures need to run inside transactions?
Can they return data or are they execution only?
Can they accept tables?
How is the application going to know that it needs to call a particular procedure?
How are you going to map from code to parameters from your stored proc?
Do the procedures need to be retriable?

There are many other questions you are going to have to ask, but this is a good start.

Thanks Pete
- I don't require the transactions as we have already implemented within the procedures.
- No need to provide the tables
- The major requirements is that it can accept any number of parameter OR without parameter.
- The procedure can be capable of executing and return data both

So keep refining those requirements. That should help you drive out the design. Don't forget that I only gave you some things to consider there, there will be many, many others.

Yeah, there's really no answer to your "question" because that's not the complete error message. It's impossible to tell you what's wrong because there's more than just a couple of lines of code in Global.asax.

Yes.

Since there are over 42,131,343 possible error messages, would you be so kind as to specify which error message you are getting? It's Friday and I'm in no mood for guessing games.
