All of this information is stored in the assembly's manifest, which is created at compile time. NET reflection classes query the assembly's manifest for information about what is contained in the assembly. Activator, contains methods to create types of objects locally or remotely, or obtain references to existing remote objects.

You can use the information obtained using reflection to dynamically create an instance of a class located in an external assembly.

Once you've created that instance you can call any public method passing the information retrieved.

Now that you have an instance of the class you can call any method contained in that class.

We need a level of abstraction to allow the application to know what methods to call and their associated parameters at run time instead of compile time. NET classes to create instances of objects and invoke methods on those instances dynamically.

Now you need to provide a layer of abstraction so that the necessary information is available at run time instead of compile time. Then, use the returned App Domain's Load method to load an assembly into the domain.

Foo implements the IValidator interface, so "v" is not null.Each programmer has developed his or her own method of validating input data in varying degrees of complexity, but generally, this has resulted in coding the data validation rules into the procedural or object code.This has meant re-compiling and re-distributing your application each time the validation rules changed.Coding validation rules in DLLs apart from the rest of the system allows you to update the rules without rebuilding the entire application, but you have to stop the application to replace the DLLs.In addition, the inherent lack of Type safety in calling DLL methods and having to load them using Load Library and Get Proc Address results in code that is difficult to understand and maintain.. At Brierley & Partners we've developed a set of classes and interfaces to perform data validation in a fraction of the time it would take using traditional C and/or COM components.

    The theory goes that when you’re learning a skill – whether it’s ninjutsu or 21st century mating rituals – you’ll make greater progress if you practise intensively. After 30 minutes on Tinder – the app that lets people hook up with the swipe of a finger – frantically registering my interest with no regard for acne, bodyweight or bad teeth, I’m rewarded with several matches. “If you want to appear confident, be armed with something to open with. Talk about the weather if you have to.” K from Tinder is a nice, slightly chubby nanny. Loads can't) My second nanny of the day, teetotal L, again from Lovestruck.
