TryParse ( "13", result1arg ) // invokes int. Calling getDeclaredMethods () method, returns a Method. When you call the getMethods () method, it will return to you a Method array with the objects of methods that have been public in the class. Create () // or: RefOutArg.Create(0) intClass. Using Java Reflection you can interrogate any class and find out all the methods that are available to you. When a method uses reflection to access class members (that is, uses the APIs belonging to the package), the reflection uses the same. Invoking methods with ref or out parameters is more awkward, but possible: int result1 var result1arg = RefOutArg. / public sealed class RefOutArg ) // sets Thread.CurrentPrincipal The RefOutArg class was invented for this purpose ( official source): /// /// A wrapper around a "ref" or "out" argument invoked dynamically. There is a work-around for this: wrapping ref or out parameters, adding a layer of indirection. Unfortunately, DynamicObject does not support the concept of ref/out parameters, even though they are fully supported by dynamic. This makes sense since dynamic may be seen as a more user-friendly type of reflection (of course, this simple interpretation ignores a lot of other DLR benefits). The general concept is to implement a DynamicObject type that uses reflection to access static members. However, this approach brings with it its own limitation. This approach was first explored in David Ebbo’s blog post “Using C# dynamic to call static members”. One can use the DynamicObject class to redirect instance member access to static member access. For example, if two different classes have the same static method defined, there is no way to use dynamic to invoke those static methods. The dynamic type is intended to represent a dynamic instance, not a dynamic class. One limitation is dynamically accessing static (class-scoped) members. Dynamic brings some very powerful semantics into the language, and naturally also comes with a few limitations. One of these features is the C# support for dynamic languages via the new keyword dynamic. NET 4.0 was a huge release, containing a wide variety of much-anticipated features.
