.net runtime type casting when using reflection
I have need to cast a generic list of a concrete type to a generic list of an interface that the concrete types implement. This interface list is a property on an object and I am assigning the value using reflection. I only know the value at runtime. Below is a simple code example of what I am trying to accomplish: public void Employ...
Invoke private method with interface as argument
Hi, I've been attempting to invoke a private method whose argument is a parameter and I can't quite seem to get it right. Here's kind of how the code looks so far: public class TestClass { public TestClass(){ } private void simpleMethod( Map<String, Integer> testMap) { //code logic } } Then I attempt to use this ...
ReflectionTypeLoadException with Silverlight serialization attributes
Hi all, I´m trying to inspect the types in a silverlight 4 assembly from a .NET 3.5 application. I have loaded the silverlight assembly with a Assembly.ReflectionOnlyLoadFrom sentence. contractsAssembly = Assembly.ReflectionOnlyLoadFrom(contractsAssemblyPath); When the .NET application tries to perform a call to GetTypes(), it throws...

MethodInfo lGetSomeClassMethodInfo = typeof(IRepository) .GetMethod("GetClass...
Get PropertyInfo from property instead of name
Say, for example, I've got this simple class: public class MyClass { public String MyProperty { get; set; } } The way to get the PropertyInfo for MyProperty would be: typeof(MyClass).GetProperty("MyProperty"); This sucks! Why? Easy: it will break as soon as I change the Name of the Property, it needs a lot of dedicated tests to ...
Finding the attributes on the properties of an instance of a class
Given an instance of a class I want to set properties on attributes at runtime. So I tried this, but as far as I can tell this finds the attributes on the class not the instance, so any changes I make to the attribute properties have no effect. var properties = myObject.GetType().GetProperties(); foreach (object prop in properties) { ...
f# types' properties in inconsistent order and of slightly differing types
I'm trying to iterate through an array of objects and recursively print out each objects properties. Here is my object model: type firmIdentifier = { firmId: int ; firmName: string ; } type authorIdentifier = { authorId: int ; authorName: string ; firm: firmIdentifier ; } type denormalizedSuggestedTradeRecommendatio...
ClassCastException when creating an instance of a class using reflection and ClassLoaders.
Hi, First of all, this is Java 1.4 (project restrictions). I'm trying to create a application manager. It loads each application's main class using it's own instance of a custom classloader. After that, it creates an instance of the main class using reflection. Each application implements a common interface so after the instance is crea...
ASP.NET MVC: How to find Controllers with [Authorize] attributes using Reflection in C#? (or How to build Dynamic Site.Master Menus?)
Maybe I should back-up and widen the scope before diving into the title question... I'm currently writing a web app in ASP.NET MVC 1.0 (although I do have MVC 2.0 installed on my PC, so I'm not exactly restricted to 1.0) -- I've started with the standard MVC project which has your basic "Welcome to ASP.NET MVC" and shows both the [Home]...
[dynamic] Different behaviours between .NET 4.0 beta 2 and last release of .NET 4.0 !
Hi. I've identified a difference of DLR between .NET 4.0 Beta 2 and the last release of .NET 4.0. In .NET 4.0 Beta 2, this code perfectly works at runtime : var dateTimeList = new List<DateTime>(); dynamic myDynamicObject = dateTimeList; object value = DateTime.Now; myDynamicObject.Add(value); Now, with last release of .NET 4.0...

dll's loaded through reflection - Phantom Bug
Ok, I got a strange one here and I want to know if any of you have ever run accross anything like it. So I've got this web app that loads up a bunch of dll's through reflection. Basically it looks for Types that are derived from certain abstract types and adds them to the list of things it can make. Here's the weird part. While devel...
What is the security risk of object reflection?
So after a few hours of workaround the limitation of Reflection being currently disabled on the Google App Engine, I was wondering if someone could help me understand why object reflection can be a threat. Is it because I can inspect the private variables of a class or are there any other deeper reasons? ...
Reflect on an ExpandoObject
I have written a nifty function that will accept a system.object, reflect on its properties and serialize the object into a JSON string. It looks like this: public class JSONSerializer { public string Serialize(object obj) Now, I want to be able to do this to serialize a dynamic/ExpandoObject, but because my serializer uses refle...
Getting a Type variable knowing the name of type C#
Hello! I'm developing a TypeTranslator class which has a method Type TranslateType(Type type). This method gets a type of an interface and if there's a class of interface name without leading I it creates it, otherwise an exception is raised. Here's some code to clearify what's written before: class Program { interface IAnimal { } ...
Reflection and Operator Overloads in C#
Here's the deal. I've got a program that will load a given assembly, parse through all Types and their Members and compile a TreeView (very similar to old MSDN site) and then build HTML pages for each node in the TreeView. It basically takes a given assembly and allows the user to create their own MSDN-like library for it for documentat...
Using LINQ and Reflection: How to query for all Classes with [Authorize] Attribute in my Assembly?
Currently, I'm trying to identify which "Controller" classes in my assembly have the [Authorize] attribute associated with them using Reflection and LINQ. const bool allInherited = true; var myAssembly = System.Reflection.Assembly.GetExecutingAssembly(); var controllerList = from type in myAssembly.GetTypes() where ...
Type hinting for functions in Clojure
I'm trying to resolve a reflection warning in Clojure that seems to result from the lack of type inference on function return values that are normal Java objects. Trivial example code that demonstrates the issue: (set! *warn-on-reflection* true) (defn foo [#^Integer x] (+ 3 x)) (.equals (foo 2) (foo 2)) => Reflection warning, NO...
How to queue and call actual methods (rather than immediately eval) in java?
There are a list of tasks that are time sensitive (but "time" in this case is arbitrary to what another program tells me - it's more like "ticks" rather than time). However, I do NOT want said methods to evaluate immediately. I want one to execute after the other finished. I'm using a linked list for my queue, but I'm not really sure how...
