Since I was young, my father has encouraged me to become a writer, so a few years ago, I entertained the idea, and bought a book by Stephen King called "On Writing". From it, I learned several aspects of good writing. One of the most memorable was to avoid adverbs ending in -ly. The reason they should be avoided is because your verbs, nouns and adjectives should describe your intentions...

I've finally done it. For a while now I've been looking for a way to organize my thoughts efficiently and effectively, while actually retaining the things I'm learning. The wiki is designed to help with that, and I've been working on it for a couple of weeks now. Generally I get my information from one of a few sources (in no particular order):1. Daily life. I learn quite a bit just by programmin...

Note: This post was originally posted on my blog site at http://blog.codinglight.com/. I've included it here for completion's sake, but, of course, the Catapult site is not running on Blogger, nor have I had any issues with the templates on the Catapult blog site. Nevertheless, there is some information here regarding simplicity while programming, and I've included this post because I feel that...

Plugin frameworks often rely on runtime assembly resolution, and sometimes the assemblies to be resolved don't lie within the directory structure of the executable, nor are they located in the GAC. In these cases, you can use the AppDomain.AssemblyResolve event to resolve assemblies at runtime. The key with the AssemblyResolve method is that it must be put into place before attempting to instanti...

C# allows method overloading. An overload is defined as a method that has the same name as another method, and differs only in the number and/or type of parameters it receives. (Technically, .NET allows creation of overloads based only on the return type but this construct is not allowed in C#).The .NET Framework uses method overloading with several of it's methods. For example, the Activator.Cre...

This is an all-too-common question on the forums for me not to address it here. This post concerns a very basic C# concept. Sometimes, when adding a code snippet, it's possible you might get an error that says something to the effect of "The name "xxx" does not exist in the current context". At compile time, a namespace reference must be found in order to resolve classes that ...

Make sure you don't step on your own toes. The following code illustrates...using System;using System.IO;internal class Program{ private static void Main(string[] args) { string directory = @"C:\atemporaryfolder\"; Directory.CreateDirectory(directory); Environment.CurrentDirectory = directory; Directory.Delete(directory); }}Who's using the folder? Yo...

Can't believe I missed this one...var items = new string[] { "David", "Jennifer" };versus:var items = new[] { "David", "Jennifer" };Yep, that's right! "new[]" is okay. The compiler will infer the type of the array based on the type of the items within the squigglies....
