I'm trying to writing a generic method that will load a record of a specific type, with a specific ID. Here's one way that works: public abstract class LinqedTable<T> where T : LinqableTable { public static T Get(long ID) { DataContext context = LinqUtils.GetDataContext<T>(); var q = from obj in context.GetTable<T>() whe...
I'm a C/C++ programmer recently working in C#, and i'm trying to do some fancy initialization stuff that I've run into some trouble with. The best and easiest example i can come up with would be that I want to create an "Eager" Singleton - one that is created immediately at program startup, but without me requiring to go into the main f...
Hello All, I'm adding functionality to one of our existing (but broken) systems. It grabs an XML file from a web service, parses it and then does some stuff before packing it back into our database. the previous developer (who has now left) left me this little gem: http://dl.getdropbox.com/u/109069/wut.GIF and I wonder if there's a ...
I have a class that should read a message, extract its type from the envelope and then call a method that have to process the message; at each message type is associated an enum member. There are 30+ message types. One way to dispatch the message is to just use a switch, but it's really ugly and error-prone (have I already tract that c...

Ok. So I have some code that maps certain controls on a winForm to certain properties in an object, in order to do certain things to the controls when certain things happen to the data. All well and good, works fine. Not the problem. The issue is, to add items to the mapping, I call a function that looks like: this.AddMapping(this.m...

Hi, I am fairly new to reflection and I would like to know, if possible, how to create an instance of a class then add properties to the class, set those properties, then read them later. I don't have any code as i don't even know how to start going about this. C# or VB is fine. Thank You EDIT: (to elaborate) My system has a dynamic ...

I have a ASP.net application that is referencing a external assembly that I need to dynamically load and discover any types implementing a known interface. The problem I am having is that the type I reflect does not match the same interface that is running and so I cannot cast it. Example: This code is run in ASP.net app. var assembl...

I am using reflection to get the values out of an anonymous type: object value = property.GetValue(item, null); when the underlying value is a nullable type (T?), how can I get the underlying type when the value is null? Given int? i = null; type = FunctionX(i); type == typeof(int); // true Looking for FunctionX(). Hope this make...
I may be asking this incorrectly, but can/how can you find fields on a class within itself... for example... public class HtmlPart { public void Render() { //this.GetType().GetCustomAttributes(typeof(OptionalAttribute), false); } } public class HtmlForm { private HtmlPart _FirstPart = new HtmlPart(); [Optional] //<-- ...
I want to render (for internal debugging/info) the last modified date of an assembly, so I know when was a certain website deployed. Is it possible to get it though reflection?

Somebody that I work with and respect once remarked to me that there shouldn't be any need for the use of reflection in application code and that it should only be used in frameworks. He was speaking from a J2EE background and my professional experience of that platform does generally bear that out; although I have written reflective app...

Is there any implications of loading types dynamically from a .NET assembly that is executable (.exe) compared to loading types from an .NET assembly compiled into a .dll? What is the best and quickest way to test .exe and .dll if it is a .NET executable or not (just not a big fan of the BadImageFormatException)? Thank you. ...
