Reflection 4 University Of York Students Union Yusu

Reflection 4 University Of York Students Union Yusu I want to dynamically create taska or taskb using c# reflection (activator.createinstance). however i wouldn't know the type before hand, so i need to dynamically create taska based on string like "namespace.taska" or "namespace.taskab". I have a class with a private static final field that, unfortunately, i need to change it at run time. using reflection i get this error: java.lang.illegalaccessexception: can not set static final.

University Of York Students Union Is there a way in c# where i can use reflection to set an object property? ex: myobject obj = new myobject(); obj.name = "value"; i want to set obj.name with reflection. something like: reflection. What is reflection, and why is it useful? i'm particularly interested in java, but i assume the principles are the same in any language. Reflection is slow. private members reflection breaks encapsulation principle and thus exposing your code to the following : increase complexity of your code because it has to handle the inner behavior of the classes. what is hidden should remain hidden. makes your code easy to break as it will compile but won't run if the method changed its name. Use method invocation from reflection: class c = class.forname("class name"); method method = c.getdeclaredmethod("method name", parametertypes); method.invoke(objecttoinvokeon, params); where: "class name" is the name of the class objecttoinvokeon is of type object and is the object you want to invoke the method on "method name" is the name of the method you want to call parametertypes is.

For completeness, there is also the componentmodel, exposed by typedescriptor.getproperties ( ) which allows dynamic runtime properties (reflection is fixed at compile time). How can i get all the public methods of class using reflection when class name is passed as a string as shown in the below method. ? private methodinfo[] getobjectmethods(string selectedobjclas. I am trying to figure out how you could go about importing and using a .dll at runtime inside a c# application. using assembly.loadfile() i have managed to get my program to load the dll (this part. I asked a question yesterday regarding using either reflection or strategy pattern for dynamically calling methods. however, since then i have decided to change the methods into individual classes.
