When you create a class, you are probably pretty sure that it works. You will, after all, have put it through its paces during development. You ll also have run your system with the component in place, checking that it integrates well, and your new functionality is available and performing as expected. Can you be sure that your class will carry on working as expected though That might seem like a silly question. After all, you ve checked your code once; why should it stop working arbitrarily Well, of course it won t; nothing happens arbitrarily, and if you never add another line of code to your system, you can probably breathe easy. If, on the other hand your project is active, then it s inevitable that your component s context will change, and highly likely that the component itself will be altered in any number of ways. Let s look at these issues in turn. First, how can changing a component s context introduce errors Even in a system where components are nicely decoupled from one another, they remain interdependent. Objects used by your class return values, perform actions, and accept data. If any of these behaviors change, the effects on the operation of your class might cause the kind of error that s easy to catch the kind where your system falls over with a convenient error message that includes a file name and line number. Much more insidious, though, is the kind of change that does not cause an engine-level error, but nonetheless confuses your component. If your class makes an assumption based on another class s data, a change in that data might cause it to make a wrong decision. Your class is now in error and without a change to a line of code.

Both class and struct objects can implement interfaces. As in Delphi, the syntax that you use to declare that an object supports an interface is very similar to the syntax that you use for inheritance. More precisely, the optional colon after an object s name is followed by a commaseparated list of identifiers. In a class type, the first identifier in the list can be a base type; all the other identifiers are interfaces that this object implements. An object implements an interface by implementing all of the methods and/or properties in the interface, in one of two ways. The first way is a public method or property with the right name and prototype. The second way is a method or property that has no access modifier (and is thus private) and has a name qualified with the interface name. In both cases, parameter type and order matters, but parameter names do not. class Implementor: IBaby { public int Fn(int Param) { return Param; } // could be "public double Fn(double)" but NOT "double IBaby.Fn(double)" double IDaddy.Fn(double Param) { return Param; } int IBaby.RPM { get { return 45; } } } Note the way that the qualified implementation of double IDaddy.Fn(double) needs to be qualified with the interface that actually declares it IDaddy not the descendant interface that the type is implementing.

C# tutorial: Add annotations to an existing PDF
To add the text annotation to the PDF document, you need to create an instance of PdfReader class to read pages from the PDF source file. Then create an instance of the PdfStamper class. Then use the AddAnnotation method of the PdfStamper class. This method has two arguments: the PdfAnnotation object and page number.

When you implement an interface method as a public method, you can call that method normally, through an instance reference By contrast, when you implement an interface method as a private method with an interface-qualified name, you can only call that method through the interface There are two common reasons to accept this limitation and use an interfacequalified name The first is that you actually want the limitation: that you are willing to expose the functionality through the interface, but there are good reasons for it to not be part of the class s set of public methods For example, sometimes you want a class to have no public members, only interfaces that it implements.
