Part 1 - C# Tutorial - Introduction.avi. C# - A C# 6.0 Language Preview. By the time you read this, Build—the Microsoft developer conference—will be over and developers will be thinking about how to respond to all that was presented: embrace immediately, watch with slight trepidation or ignore for the moment.

C# - A C# 6.0 Language Preview

For .NET/C# developers, the most significant announcement was undoubtedly the release of the next version of the C# compiler (“Roslyn”) as open source. Related to that are the language improvements themselves. Even if you don’t have plans to immediately adopt C# vNext—which I’ll refer to henceforth and unofficially as C# 6.0—at a minimum, you should be aware of its features and take note of those that might make it worth jumping right in. In this article, I’ll delve into the details of what’s available in C# 6.0 at the time of this writing (March 2014) or in the now open source bits downloadable from roslyn.codeplex.com.

I’ll refer to this as a single release that I’ll term the March Preview. Indexed Members and Element Initializers Primary Constructors. Probable C# 6.0 features illustrated. Adam Ralph has a list of the probable C# 6.0 features Mads Torgersen from the C# design team covered at new Developers Conference() NDC 2013 in London.

I thought it would be fun to show some before and after syntax for comparison and in doing so ended up with a few thoughts and questions. 1. Primary Constructors Shorter way to write a constructor that automatically assigns to private instance variables. Before public class Point { private int x, y; public Point(int x, int y) this.x = x; this.y = y; } } After public class Point(int x, int y) { private int x, y; } Thoughts Do you need to independently define x and y? This solution feels too constrained, would have preferred something like: public Point(set int x, set int y) That set the property and optionally created a private one if it didn’t.

More OOP Interfaces in C#, Part 2 « Arcane Code

There’s a bit more about interfaces I wanted to share. With a normal class, it can only inherit from one base class. However, it can implement multiple interfaces. By the way, this seems like a good time for a little lesson in terminology. A class inherits from another class, but it implements one or more interfaces. Let’s look at our IPerson interface from yesterday.

Using System; More OOP Interfaces in C#, Part 1 « Arcane Code. During our discussion on OOP (see my posts for the last few days) one of the key concepts was the base class.

The base class was a place where we could put code that would in turn be used by the classes that descend from the base. The use of the base class allows us to take advantage of polymorphism, the ability to treat a lot of specific child classes as if they were the same less specific, more generic type (the base). Notice a point I made a moment ago.

The base class contains code, that will be inherited. What if you have a situation where you want a common base, but you don’t have any code that will be reusable by it’s descendants? One classic example given in every book is the Shape. An example from the real world might be the concept of lunch. Implementing an interface in C# is not difficult. First, right click on your solution and select Add, New Item, and select Interface from the long list. Using System; Programming matrix operations in c# Thread programming c# Learning Resources.

C# Station C# Tutorial Lesson 13 - Interfaces

Our objectives are as follows: Understand the Purpose of Interfaces. Define an Interface. Use an Interface. An interface looks like a class, but has no implementation. So, what are interfaces good for if they don't implement functionality? Because interfaces must be implemented by derived classes and structs, they define a contract. Listing 13-1. Interface IMyInterface { void MethodToImplement(); } Listing 13-1 defines an interface named IMyInterface. Listing 13-2. Class InterfaceImplementer : IMyInterface { static void Main() { InterfaceImplementer iImp = new InterfaceImplementer(); iImp.MethodToImplement(); } public void MethodToImplement() { Console.WriteLine("MethodToImplement() called. "); } }
