I'm attempting to compare a transient object graph to an NHibernate-persisted object graph. Unfortunately my code breaks where properties of type IList<T> are concerned. The code below works fine with instances of List<T>, because List<T> implements both IList<T> AND IList. Unfortunately, NHibernate's PersistentGenericBag only implements...
I'm trying to write a trait (in Scala 2.8) that can be mixed in to a case class, allowing its fields to be inspected at runtime, for a particular debugging purpose. I want to get them back in the order that they were declared in the source file, and I'd like to omit any other fields inside the case class. For example: trait CaseClassRef...
Given Type a and Type b, how can I, at runtime, determine whether there's an implicit conversion from a to b? If that doesn't make sense, consider the following method: public PropertyInfo GetCompatibleProperty<T>(object instance, string propertyName) { var property = instance.GetType().GetProperty(propertyName); bool isCompatib...
I'm learning CIL by making my own functions at runtime with Reflection.Emit. I'm actually surprised how easy things have been up until now but I've hit something that I can't guess my way through and I can't find anything relative in the docs. I'm trying to create a function that simply prints a very simple class I have defined. If I ch...
As part of developing a small ScriptEngine, I reflectively call java methods. A call by the script engine gives me the object the method name and an array of arguments. To call the method I tried to resolve it with a call to Class.getMethod(name, argument types). This however only works when the classes of the arguments and the classes e...
I have a problem where i need to walk through an object graph and pick out a particular property value. My original solution caches a linked list of property names that need to be applied in order to get from point A to point B in the object graph. I then use apache commons PropertyUtils to iterate through the linked list calling getProp...
I am working in c#.NEt 2.0. I have a class, let's say X with many properties. Each properties has a custom attribute, an interger, which I planned to use to specify its order int he final array. Using reflection I read through all of the properties and group the values and place them into a generic list of properties. This works and I c...
How to get property.value from reflection.assembly? Dim assembly As Assembly = assembly.GetExecutingAssembly() For Each assemblyType As Type In assembly.GetTypes() If assemblyType.IsSubclassOf(GetType(Form)) Then 'Dim name As AssemblyName() = assembly.GetReferencedAssemblies() If assemblyType.BaseType....
I have an asp.net web project that references a domain project. From within the web project, I want to create an instance of a class from the domain project using reflection, but I always get null (Nothing, in VB). NOTE: I am using the non-fully qualified class name, and was hoping that a search would be performed as MSDN seems to indi...
As the name of the anonymous type is compiler generated, so is it accessible through reflection? ...
Hi, I have a question: Is there an elegant way of getting Attributes on a referenced field. Ie.: public class C1: Base { [MyAttribute] public string Field1; } public class Base { private void Do(ref string field) { if (field has attributes) DoSomething(); } } How can I get attributes of a f...
I started a "for fun, nobody knows, nobody cares" open source project (LinkSet). In one place I need to get an annotated method of a class. Is there a more efficient way to do it than this? I mean without the need of iterating through every method? for (final Method method : cls.getDeclaredMethods()) { final HandlerMethod handler...
If I have a class like this: public class Whatever { public void aMethod(int aParam); } is there any way to know that aMethod uses a parameter named aParam, that is of type int? ...
Hi I am using reflection to construct a class (ConfigBuilder) that takes a File as argument: Class myClassType = Class.forName(className); Class[] types = new Class[] { File.class }; Constructor cons = myClassType.getConstructor(types); Object[] constructorArgs = new Object[] { myFile }; cb = (ConfigBuilder) cons.newInstance(construct...
For whatever reason, I can't seem to get the list of types in a referenced assembly. Not only that, I can't even seem to be able to get to this referenced assembly. I tried AppDomain.CurrentDomain.GetAssemblies(), but it only returns assemblies that have already been loaded into memory. I tried Assembly.GetExecutingAssembly().GetRefer...
I am using FileHelpers to parse CSV files whose structure is unknown using the following code: string cd = string.Format(@"[DelimitedRecord(""{0}"")] public sealed class ImportClass {{ [FieldQuoted('{1}')] ...
Hi everyone! I am trying to get a value of a Window as follows this refers to the main window (window1) Type type = this.GetType(); PropertyInfo pi = type.GetProperty("Left"); object obj = pi.GetValue(type, null); But I get an "Object does not match target type using" error. What is wrong? ...
my project is written in c#. I have a usercontrol that I've designed. In that usercontrol I want the ability to look through the form the control is placed on using reflection to look at all other controls on the form. How can I go about doing this? I've used reflection to go through dll's but not for something like this. in summary: M...
I have an abstract class and I want to initalize it to a class that extends it. I have the child classes name as a string. Besides this... String childClassString; MyAbstractClass myObject; if (childClassString = "myExtenedObjectA") myObject = new ExtenedObjectA(); if (childClassString = "myExtenedObjectB") myObject = new Ext...
Say I have a singleton-ish, factory-ish, reflection-ish class that receives some input, and spits back a new instance of a concrete implementation of some interface. What kind of design is this? Is there a better way to do what I want? Here's some code to illustrate the point: using System; using System.Collections.Generic; // stat...
