From my blog analytics I can see, quite many of you seeking methods for doing wildcard matching in C#. You found my blog post from last year and is maybe not happy using a Visual Basic assembly for a simple wildcard match. Obviously this is not the only method. You can writer your own from thegound up, and for[…]
Sometimes functionality needs to be global and grouped together, without no direct relationships to objects. In these cases I create helper classes. I have my own way of doing such, but I see other developers during a variation on the same theme in not so optimal way. Let’s take the “bad” solutions one at a[…]
On numerous occasions I’ve been involved in projects, where I’ve had an instance of a given object type present in one namespace and the need to convert it to an object type with exactly the same signature, but in another namespace.

A couple of years ago, I got involved in a project where a developer has ported some code from mainframe to .NET. The code had to evaluate mathematical formulas on runtime. This was developed – as the matter of fatct – it was copied from some open source code found on the internet, that could[…]
On numerous occations I’ve had to do some runtime creation of C# code. In the early days, I was tempted to directly write each source line to a file. But quickly discovering, that I needed a solution where I could use template based generation of texts (source code). Where I can easily change certain parts[…]
Working on a project of porting a Websphere Java (JSP/Struts) based application to C# (ASP.NET MVC/Razor), I had this morning quite some fun with strings. Some unexpected behaviour and an error on my part (taking a shortcut) gave me some minutes of headache. First challenge – space is space right? The Java code is ported[…]
