Every time I need to work with the contents of text-based files in an ASP.NET application I invariably start off thinking about using the various static methods on the
System.IO.File class to extract the text and then some string manipulation or Regex to parse the content into some kind of structure. And, just in time, I remember the
TextFieldParser class that hides itself away in the
Microsoft.VisualBasic assembly. The purpose of this article is to introduce this component to a wider audience, but also to serve me as an aide-mémoire in terms of the basic usage, which I always have to look up.

Visual Studio 2015 introduces a completely new version of ASP.NET, but it also includes version 6 of the C# language. Previous new versions of C# have heralded substantial changes like the introduction of
await in version 5,
dynamic in version 4, LINQ in version 3 and so on. There are no major feature changes or introductions in version 6, but there are a number of syntactical improvements that you are likely to use on a daily basis. Here's a rundown of them.

I've had a review copy of Jeffrey Richter's CLR via C#, Third Edition for some months, and it has taken until now to get round to publishing my thoughts on the book. It's not my fault. I blame the book. It made me forget why I was given a copy in the first place. Let me explain...

Here's something that comes up often in forums - How To Find Yesterday in SQL or C#. Piece of cake, if you know how, but tricky if you don't. And especially tricky to get the right value if you are not clear on the requirement.

Following on from the recent spate of extensions methods I've posted, here's another I use to convert URLs and email addresses into links within HTML. You may want to restrict users from submitting HTML tags via forms in your application, which means that URLs and email addresses that they submit appear as plain text unless they are subjected to some kind of processing.

The most recent addition to my Cheat Sheets features details of all the Exceptions that can be found in the most commonly used assemblies within ASP.NET development. Compiling this information was an interesting challenge. I could have simply copy-pasted from MSDN, but that would have been extremely tedious. Instead, I ended up with a blend of Linq to XML, Reflection, a dash of Regex and the Global Assembly Cache Tool - gacutil.exe. Here's the full story.

Here's a list of Exceptions that can be found in the assemblies which are most commonly used in ASP.NET development. Ideally, you should be as specific as possible when catching or throwing Exceptions. The more specific you are, the less work the CLR has to do in locating the appropriate catch block, and the more informative your error messages are, which should help speed up identifying the source of any problems.

Delegates in C# cause a fair amount of confusion, but with the introduction of LINQ to SQL and the profilic use of the Lambda Expression operator (=>) that it has foisted on an unprepared batch of beginners, an understanding of how these two items are related, together with Anonymous Methods becomes more important. Most definitions of Delegates that you find start off with comparing them to "function pointers in C or C++", which is great if you ever worked with those languages and understood them, but not helpful to new programmers. Here's my attempt at simplifying the various concepts.

The previous iTextSharp article looked at bringing images into a PDF file and working with them. Sometimes, however, you may want to draw shapes and lines within the PDF and not rely on images. iTextSharp includes a lot of functionality that covers simple drawing to quite complex shapes. This article gets you started. Previous articles are listed below:
