I wanted to attempt a brief post before the holidays, so I decided to quickly revisit part a post I wrote a few weeks back on The Generic Func Delegates, and in particular, the sidebar on using Func as a generator for unit testing. At the time, I did not give that short sidebar the attention I really wanted, including showing the setup of the unit tests and discussing the performance impact (if any) of such a practice. So this week I hope to rectify this by revisiting and enhancing the discussion. (more)

C#/.NET Little Wonders: The Generic Func Delegates

Back in one of my three original “Little Wonders” Trilogy of posts, I had listed generic delegates as one of the Little Wonders of .NET. Later, someone posted a comment saying said that they would love more detail on the generic delegates and their uses, since my original entry just scratched the surface of them. Last week, I began our look at some of the handy generic delegates built into .NET with a description of delegates in general, and the Action family of delegates. For this week, I’ll launch i...

Lambda expressions can be cryptic, but they’re quite simple once you get the hang of them. One thing that can trouble developers is the ability to write recursive calls within a Func, something that’s quite simple inside of a method... (more)

I wrote about continuation-passing style in a post a couple of months ago, and I’ve had time to ruminate over it since. One consideration I had is whether to return a type or not. This is easily handled by overloading the method. I also describe how I created an executable with Func (more)

Summation Functions

Creating a summation function in C# isn’t difficult in itself. After all, it is perfectly reasonable to create functions that consist of more than one line. What is interesting is abstracting it so that any function can become a summation function. (more)

Call a Function to Infinity
published 1028 days, 1 hour, 31 minutes ago posted by KodefuGuruKodefuGuru 1028 days, 21 hours, 12 minutes ago

What if the resulting value of a function was used to feed the parameter of the same function? It easy enough to call a function, get its result, then pass it back in. However, I wanted to abstract this and make it work for anything whose generic parameter type is the same as the generic result type. If it’s abstracted, there must be some arbitrary end point… right? How about infinity? (more)

Playing with C# Func and ADO.NET

I’ve always liked the look of the generic Func and I think the possibilities behind it are awesome. However, it’s usually difficult for me to find a good place to use it. I’m probably just not that used to using it yet and I am missing out on some huge advantages. Ignorance is not bliss sometimes :) So anyhow, I was playing with the good ole ExecuteScalar & ExecuteNonQuery commands on the IDbCommand interface and came up with something kinda cool. At least I thought so… (more)
