Like strings, dates and times are represented using special types, and so deserve some attention. In this lesson we learn how to work with Date and Time data, how to create new instances of DateTime, how to add time, format the data for display, and more. Furthermore, we discuss the TimeSpan class…

This lesson digs into more details about Classes—what exactly happens when you create a new instance of a class? What exactly is a reference to an instance of a class? How does passing the reference to a method affect a class? We also review overloaded methods, talk about static versus instance…

This lesson begins by discussing the scope of variables within code blocks, and progresses to explain how accessibility modifiers such as Public, Private, and Protected are used by the .NET Framework Class Library to expose or hide implementation of their given services to consumers of that given…

Now that you have a good sampling of basic C# syntax under your belt, it's time to tackle some more challenging topics. Classes are integral to the .NET Framework, particularly the .NET Framework Class Library. This lesson demonstrates how classes are defined and new instances are created, how to…

Exceptions occur when an application experiences some unexpected problem at run time. This lesson discusses how to use the try catch finally block to anticipate potential problems and attempt to shield the end user from those problems as much as possible. We discuss best practices when checking for…

Collections are a more powerful form of arrays. In this lesson we demonstrate an "old style" collection (pointing out its limitations) as well as several of the newer, strongly typed generic collections (List<T> and Dictionary<T1, T2>) utilizing the generics syntax. Download…

Classes can contain many different types of information, not just Properties and Methods. In this lesson we demonstrate the use of Enumerations because in the .NET Framework Class Library, properties can often be set only to a predetermined subset of possible values. To illustrate this point we…

We've avoided any talk about Namespaces; however, they serve an important role in the .NET Framework Class Library as well as in our custom class libraries. In this lesson we explain how Namespaces allow us to disambiguate classes that may share the same name. Additionally, we explain how the .NET…

Welcome back to another Visual Studio 2010 and .NET Framework 4.0 Week video. In this latest installment, we catch up with Karen Liu, Lead PM on the C# and Visual Basic IDEs. Karen shows us improvements being made to better enable test-driven development. Covered are features…
