I am trying to find a way to get the source code for (user defined) PHP functions in a string. For normal code this is easy, using reflection I can find the file and linenumbers where the function is defined, then I can open the file and read the function source code. This will not work if a function is defined in eval'd code. I do not...
Currently I have the function CreateLog() for creating a a log4net Log with name after the constructing instance's class. Typically used as in: class MessageReceiver { protected ILog Log = Util.CreateLog(); ... } If we remove lots of error handling the implementation boils down to: [EDIT: Please read the longer version of C...

Hi there is there a possibility to get an object from a specific namespace? Perhaps with the System.Reflections? I want to get all objects from type ITestType in the namespace Test.TestTypes as Objects so that I have a list of instances of TestType1, TestType2, TestType3 and so on. Can Someone help me? I don't know where to search for th...
Hi, I have an expression tree I have created by parsing an Xml using the expression class in C#. See this question. I only have Add, Subtract, Divide, Multiply, Parameters, And and Or in my Expression Tree. Is there a way to convert this ExpressionTree into a callable method? ...or do I have to emit the IL manually? Kind regards, ...
I have an application the will load usercontrols dynamically depending on the user. You will see in the example below that I am casting each user control via switch/case statements. Is there a better way to do this? Reflection? (I must be able to add an event handler Bind in each control.) override protected void OnInit(EventArgs e) {...
What is the origin of the term reflection? It seems more like introspection. Why isn't it called that? Introspection: A looking inward; specifically, the act or process of self-examination. Reflection: the act of reflecting or the state of being reflected. an image; representation; counterpart a fixing of the thoughts on something;...
I'm building a custom property grid that displays the properties of items in a collection. What I want to do is show only the properties in the grid that are common amongst each item. I am assuming the best way to do this would be to find the the common base class of each type in the collection and display it's properties. Is there any e...
i have a winforms applicatoin that has a lot of implementations of IOrderDataLoader. Other teams are starting to build their own new implementations of IOrderDataLoader. So we switched our app to look in a directories of Dlls and load all classes that implement IOrderDataLoader using reflection. This way other groups can deploy their ...
Is it possible to reflectively instantiate a generic type in Java? Using the technique described here I get an error because class tokens cannot be generic. Take the example below. I want to instantiate some subclass of Creator that implements Creator. The actual class name is passed in as a command line argument. The idea is to be able ...
Assuming the following hypothetical inheritance hierarchy: public interface IA { int ID { get; set; } } public interface IB : IA { string Name { get; set; } } Using reflection and making the following call: typeof(IB).GetProperties(BindingFlags.Public | BindingFlags.Instance) will only yield the properties of interface IB, wh...
This is a somewhat bizarre question. My objectives are to understand the language design decision and to identify the possibilities of reflection in C++. Why C++ language committee did not go towards implementing reflection in the language? Is reflection too difficult in a language that does not run on a virtual machine (like java)? If...
I'm trying to use reflection to get a property from a class. Here is some sample code of what I'm seeing: namespace ConsoleApplication1 { class Program { static void Main(string[] args) { System.Reflection.PropertyInfo[] tmp2 = typeof(TestClass).GetProperties(); System....
I am looking to get a list of the column names returned from a Model. Anyone know how this would be done, any help would be greatly appreciated. Example Code: var project = db.Projects.Single(p => p.ProjectID.Equals(Id)); This code would return the Projects object, how would I get a list of all the column names in this Model. Thanks...
I'm currently working with a specialized, interpreted, programming language implemented in Java. As a very small part of the language, I'd like to add the ability to make calls into Java. Before I dive into all of the nitty-gritty of reflection, I was wondering if anyone knew of a general library for doing the "backend" part of invoking...
I was wondering if anyone knows of a quick way or if anyone has written a reflection tool to tell which objects in a solution are not marked as serializable. I'm switching a site over to a StateServer and i need to have all objects marked as serializable. I don't want to miss any. Also, second part do enums have to be serializable? T...
public class Address { public string ZipCode {get; set;} } public class Customer { public Address Address {get; set;} } how can I access eitther "ZipCode" or "Address.ZipCode" with reflection? For example: Typeof(Customer).GetProperty("ZipCode")? ...
Hi, I need to show an object in PropertyGrid with the following requirements: the object and its sub object must be read-only, able to activate PropertyGrid's CollectionEditors. I found a sample that's closely match to what I need but there's an unexpected behaviour I couldn't figure out. I have more than one PropertyGrids each for dif...
Hi, I have a similar question to this one except I need to loop all the sub objects and change the property to read-only Please check my code below. This one loop only the main object. When I tried to loop its sub objects, I got an overflow. Thanks. Public Class ReadOnlyTypeDescriptor Inherits CustomTypeDescriptor Priva...
