Now that we've seen how to define types in C#, we'll investigate how to design and implement these types correctly and effectively in the following chapters. Chapter 2: Type Members Overview One of the most basic building blocks in object-oriented programming is the class. NET platform will be encapsulated in classes. Becoming an effective class designer is essential to becoming a successful object-oriented programmer. Effective class designs also simplify maintenance and versioning. Once a class is designed and clients are consuming the class, it becomes difficult to change or version.

You can see that if your application is performing a lot of boxing and unboxing then the overhead in terms of performance and memory usage can be significant. Other Boxing Scenarios The previous example gives one scenario in which a value type is passed as a parameter to a method requiring a reference type. Boxing will also occur whenever you implicitly or explicitly cast an instance of a value type to a reference type. For example, the following code will create a boxed version of an int: int number = 43; object o = number; int anotherNumber = (int)o; // define a value type // boxes a copy of number // unboxes the copied value Boxing also happens when you cast a value type to an interface.

NET), offer similar type members. NET native intermediate language, it becomes very difficult to tell what language the code was actually written in. NET provides to restrict the visibility of type members. At times, classes need the ability to restrict what type members are visible to different pieces of code. For example, a class may need to have a function that is only callable from within the same namespace. Applying the proper access modifier gives us the flexibility to provide such restrictions.
