In all my latest posts regarding reflection all I've done is getting values and invoking methods and this can confuse you into thinking that when using reflection stuff is read only, but it's not. Just as we have GetValue we also have SetValue. [...]
In the previous post I focused on getting values from an instance and getting information about the class itself. In this post I want to focus on getting even more information about the class and the properties in it, I want to get information about the attributes that I using!
To get information about attributes either on a class or on a property you do this by invoking methods on the Attribute class, these methods are static so you won't need an instance of the Attribute class. [...]
Lately you've seen me use something called reflection, but what is reflection? If we look it up on MSDN we get a quite good answer, but to the untrained eye it might be a bit cryptic [...]
I want to explore reflection by playing with both reflection, anonymous types and dynamically typed things all at once! My goal is not to be confusing or anything, but it is to leave out the parts that are redundant. [...]
In C# 3.0 something called anonymous types was introduced, this means that a certain context can have a type that is not defined anywhere except in that context. This has been seen a lot in LINQ-queries over the years. Here's an example of an anonymous type:
var person = new { Name = "Filip" };
[...]
If you come from a world filled with JavaScript you might be used to seeing the click handler logic defined at the same place as where you defined the click handler itself. For instance, look at this code:
$("#submit").click(function(){
performPostAndRedirect();
});
I think it's safe to say that this kind of code is very usual and that it's nothing wrong with it, in fact, it's easy to read and easy to understand and for me readability is something that is very important. [...]
My last posts have been a lot about what you can do to explore the dynamic world in .NET and what it might be good for. But I think it's time for some real fun with dynamic!
So go ahead and fire up Visual Studio, see to it that you got NuGet installed, now let's get rocking! [...]
In my previous post I talked about how you can extend the DynamicObject so that you can override TryInvokeMember and TryGetMember. However, these are not the only methods that you can override. I wanted to take a brief moment and talk about one of the other methods that you can override as well, this being TryInvoke. [...]
If you have ever programmed in a dynamic programming language you know that you can pretty much ask for anything on any object, consider this code in any dynamic programming language: [...]
Meanwhile I am planning and writing manuscript and code samples for my upcoming video series that will cover "Programming fundamentals using C#", I thought it was time for a short post on some dynamic programming in C#! [...]
For those that don't want to install the Windows 8 Developer Preview on their workstation just to try out and develop applications in Visual Studio 11, I can happily say that Visual Studio 11 runs perfectly fine side by side Visual Studio 2010 on Windows 7! [...]
This is my fourth screencast, talking about generic programming in C#. In this session I talk about how life was before we had Generics and then I talk about what generics solves for us. [...]
This is my third screencast, talking about the dynamic keyword in C# 4.0. In this session I talk briefly about the dynamic keyword, where you might have seen it before and give some examples on how you can use it. I won't go in to depth on the DRL, ExpandoObject or when/when not to use the Dynamic Keyword, that's a whole other video. [...]
It seems like the videos on C# 5 and the Async CTP were appreciated so I am working on some more screencasts. They will be a bit different than the Async CTP videos though. [...]
This question originates from StackOverflow, but as I see there are a lot of beginners that ask this question, I wanted to share the answer on my blog as well. So, WPF vs WinForms - Which is easier to learn? [...]
This is my second screencast, talking about the C# 5 async ctp. In this session I show how you can refactor old code that is using the task parallel library or a background worker to run time consuming operations asynchronously.
I also touch the surface on what continuation is and how it has been acheived using TPL and how it makes life easier when using async and await. [...]
I recently recorded a screencast talking about the C# 5 Async CTP, keep in mind that this is my first screencast ever, so please give me your constructive comments. [...]
It's been almost six months since my last blog post here, it's not like I don't have anything to write, but the time I have over at the end of the day just doesn't end up so that I have time to write here. I'll try to get some more time to write here since I really do have a lot of interesting things that I want to share! [...]
This is by far the most asked question I've seen around the net besides the obvious questions like "How do you do X and why doesn't Y work?". There is a simple answer: If the code works and is patchable, we don't need to rewrite.
I've heard that line countless of times from both customers and PM:s when arguing about rewriting old systems and to be fair, it's not an invalid statement. Why should be re-build something when it is properly working? In my opinion there are a couple of reasons why you would need to consider rewriting code that is working. [...]
More and more apps today uses only the native application as a shell around their web-based application to get their app into App Store. A drawback with doing this is that you might get really annoying load times and you have to decide where to put the "wait for the data"-scene. [...]
Lately I've experimenting a bit with parsing XML in Objective-C and discovered something that I'd like to share with you all.
First of all, consider the following "standard" way of downloading an XML and parsing it [...]
After attending Scandinavian Developer Conference in Sweden 2010 and attending the talk from Roy Osherove ( http://osherove.com/ ) Test Driven Development ( TDD ) has been something that I have tried to focus a bit more on. [...]
Once again, there was a little mistake in the last post I posted here which clearly didn't effect the result that much. But it is still worth mentioning again. The ^ was not meant to be XOR, I was clearly thinking of Math.Pow. [...]
As .NET 4.0 will be released in a couple of weeks and the RC has been out for a while. It's about time that I write something about the new helpful features of .NET 4.0. One of these helpful things are the Parallel Extensions and Parallel helpers that allowes you to do parallel programming. [...]
Function pointers? you might ask yourself, well this little trick gets handy sometimes, I will provide an example of a practical use in a later post on the next euler solution. Might actually do it in C too just to prove that C is still neat. [...]
So I've decided to start a new project, to solve as many euler problems as possible from http://projecteuler.net/, in Python! The task in hand is not only to solve them but to think outside the box and add new features to the code which might become suitable in the future, who knows. [...]
Let’s assume that you run a company, no matter if the company is big or small. Just imagine having to build a project where you know that your current staff either doesn’t have the right knowledge to solve this problem or the number of staff members is not sufficient. This is where your company will face a problem, either you hire some new personnel or you consider Outsourcing your project. In this text, we will talk only about outsourcing when it comes to information technology projects not any other work fields such as call centers etc. [...]
Classes, inheritance and polymorphism can sometimes be somewhat hard to understand. So a practial example suits many well. Therefore this will be a tutorial where i will touch the areas of classes, pointers, inheritance and polymorphism.
[...]
First off, we need to clearify what a some of the expressions i will use mean. These are the following expressions:
Assuming that you know about a computer having RAM ( Random Access Memory ) which allows you to store information and have this accessable faster than you would on a secondary memory like a harddrive and/or cd-rom.
When a program is executed there is a part in the memory reserved for this application to use, this "space" is called the Stack; The stack is always the same size and it's not possible to change it's size on any way.
The Heap is also a "space" on your memory, actually it's all the memory not allocated as a stack. So when your stack is defined, everything else can be expressed as the Heap. [...]
Often when developing software such as websites, windows ( or any other operative system for that matter ) programs, the begining of the progress is quite simple; you have your ideas and may have some thoughts about how to implement everything. But what often is forgot when developing software is the importance of thinking ahead, thus, planning for a larger software that you have in mind. [...]
