Online course
Visual Studio C#(csharp)
In this course you will learn some important issues about object-orientation such as inheritance, classes, parameters, among others.
|
Class
Vídeo
1) Creating classes and objects.
Description: Object-Oriented languages like C# and Java are based on classes and objects. A class is a prototype (like an Employee), and an object is a specific instance of the class (like John).
In Object-Oriented languages everything is an object. |

Inheritance and Parameters
Vídeo
2) Inheritance
Description: Inheritance is one of the pillars of object-oriented programming. It has to
do with creating classes from other existing classes. This feature is very
powerful since it helps us create a hierarchy of classes that depict the
business model. |

3) Passing Parameters
Description: This video discusses passing parameters to C# methods. Some methods can do their work
without needing assitional information. Other methods, however, need additional data
to do their work. |

Objects

4) IComparable
Description: Sorting is a functionality that is used by developers almost daily. We sort
numbers, dates, student records...
C# supports sorting objects that are part of the .NET Framework. |

5) IComparer
Description: This video is a continuation of a previous video on sorting objects. In the first
video, I demonstrated how to implement the IComparable interface. In this video, I
will show how to implement the IComparer interface. |

Methods, exceptions and reflection
Vídeo
6) Extension Methods
Description: Extension method is an important feature that has been added to C# 3.0. This
feature will allow developers to add additional functionality to an existing
class without the use of inheritance, and even without the need to recompile
the class.

7) Exceptions
Description: Exceptions are anomalies that are difficult to account for when writing
programs. In this video, I will introduce how exceptions happen, and how
to handle them. |

8) Reflection
Description: Reflection is a runtime type discovery. It is one of the most important concepts in the .NET Framework. In this video, I am going to demonstrate how to use reflection to discover detailed information about a class Point. |

9) Generic Methods
Description: In this video, I will discussing generic methods. When developing applications, you
notice that you might have many methods that do almost the same thing, but with
different types (one that prints an int array, another that prints a string array...). |

Serialization
Vídeo
10) Binary Serialization
Description: Serialization is the process of persisting an object into a storage medium. In this
video, I am going to demonstrate how to serialize a Document object to a file using
the BinaryFormatter. |

11) XML Serialization
Description: XML serialization is another process of persisting objects to a storage medium. Other
forms will be SOAP and Binary serialization. In this video, I will demonstrate serializing
a document object using XML serialization. |

Interfaces
Vídeo
12) Declaration and implementation
Description: An interface is a named collection of abstract (not implemented) members. It is
declared with the keyword interface. This video will cover the first part of
how interfaces are declared and how they can be implemented. |

13) IPrintable e IClonable
Description: This video is a continuation of our introduction to interfaces. We continue our
program by adding a class that implements more than one interface (IPrintable and
IClonable). Then, we explore the use of the keyword is to discover at runtime which classes implement an interface and which ones dont. |

Delegates
Vídeo
14) What is
Description: A delegate is a type-safe object that points to another method (or multiple methods)
in the application, which can be invoked at a later time. |

LINQ to SQL
Vídeo
16) DataContext
Description: This video will start the discussion of LINQ to SQL. We are using the Northwnd database.
We are going to manually develop all the pieces instead of relying on the class designer. |

Silverlight
Vídeo
18) Introduction
Description: In this video I am going to introduce Silverlight 2.0. I will show how we can
create a Silverlight application using Visual Web Developer 2008 Express. |

19) Simple Form
Description: In this video I am going to show the layout by creating a grid of controls that prompt
the user for principal, interest rate, and term. We will also add a button with code
behind to calculate the car monthly payment based on the input from the user. |

20) DoubleAnimation, ColorAnimation
Description: In this video, I start my animation demonstration. Silverlight animation is based on changing the
value of a dependency property over a period of time. We have animations for different data types:
DoubleAnimation, ColorAnimation. |

21) AutoReverse
Description: In this video we continue our animation discussion. I will change the animation that we created in
the previous video by adding a button that will trigger the animation. |

24) Brushes
Description: This video will discuss brushes, specifically LinearGradientBrush. We will create a
canvas with a rectangle. We will fill the rectangle with a LinearGradientBrush that
contais GradientStops with colors and offsets. |

27) Pincel Imagem
Description: In this video I will illustrate the use of the ImageBrush. I will fill a rectangle with
an ImageBrush, and show how I can change some properties to stretch the image and align
it within the rectangle. |

LINQToXML
Vídeo
41) Attributes
Description: This video continues our discussion on LINQ to XML. We will look at how we can
retrieve specific elements from the XML file. Then, we discuss attributes: how
we can select them, add new ones to the document and remove current ones from
the document. |

Description: In previous videos we loaded an existing xml file and queried existing books. In
this video, we will parse the xml from a string, and apply from/where/select to
the parsed xml. |

43) OfType
Description: Using LINQ to XML we can select text in a document using OfType. This video
will demonstrate how that can be done. Also, we can union two sequences of nodes
using the Union() method, and display the path to a specific nodes. |

44) Operator
Description: This video will show you how you can use the familiar new operator to create a
node (or list of nodes). Then, we will use All to find whether the nodes satisfy
a certain condition. Finally, we will sort the book authors in ascending order. |
