Mapping from a type to an instance of that type

A question came up on Stack Overflow yesterday which I've had to deal with myself before now. There are times when it's helpful to have one value per type, and that value should be an instance of that type. To express it in pseudo-code, you want...

Why boxing doesn't keep me awake at nights

I'm currently reading the (generally excellent) CLR via C# , and I've recently hit the section on boxing. Why is it that authors feel they have to scaremonger about the effects boxing can have on performance? Here's a piece of code from the...

DotNetRocks interview

Last Monday evening I had a chat with the guys from DotNetRocks , and today the show has gone live . I wouldn't claim to have said anything particularly earth-shattering, and regular readers will probably be familiar with many of the themes anyway...

Non-nullable reference types

I suspect this has been done several times before, but on my way home this evening I considered what would be needed for the reverse of nullable value types - non-nullable reference types. I've had a play with an initial implementation in MiscUtil...

Formatting strings

A while ago I wrote an article about StringBuilder and a reader mailed me to ask about the efficiency of using String.Format instead. This reminded me of a bone I have to pick with the BCL. Whenever we make a call to String.Format , it has to parse the...

Copenhagen talk on C# - what do you want to hear about?

I've created a Google moderator page for the C# talk I'll be giving in Copenhagen. I don't know whether there will be internet access at the event itself (for people to create and vote up/down questions during the talk) but at least as there's...

Book review: Pro LINQ - Language Integrated Query in C# 2008, by Joe Rattz

I'm trying something slightly different this time. Joe (the author) has reacted to specific points of my review, and I think it makes sense to show those reactions. I'd originally hoped to present them so that you could toggle them on or off,...

Logging enumeration flow

I'm currently reading Pro LINQ: Language Integrated Query in C# 2008 by Joe Rattz and yesterday I came across a claim about Enumerable.Intersect which didn't quite ring true. I consulted MSDN and the documentation is exactly the same as the book...

Core .NET refcard now available

Same drill as before - and same registration requirements (although if you registered before, you don't need to register again). The Core .NET refcard touches on some of the topics which I personally need to refer to MSDN for most often. It covers...

Lessons learned from Protocol Buffers, part 4: static interfaces

Warning: During this entire post, I will use the word static to mean "relating to a type instead of an instance". This isn't a strictly accurate use but I believe it's what most developers actually think of when they hear the word. A...

Lessons learned from Protocol Buffers, part 3: generic type relationships

In part 2 of this series we saw how the message and builder interfaces were self-referential in order to allow the implementation types to be part of the API. That's one sort of relationship, but in this post we'll see how the two interfaces relate...

Lessons learned from Protocol Buffers, part 2: self-referential generic types

In the first part of this series we saw that a message type and its builder are closely related. The tricky bit comes when we want to define an interface describing messages and builders. Although some members clearly depend on the data being built (the...

Lessons learned from Protocol Buffers, part 1: messages, builders and immutability

My port of the Protocol Buffers project has proved pretty interesting. I thought I'd share some of the lessons I've learned along the way, as well as some of the frustrations at concepts I still can't express in C#. This was originally all...

Pre-Copenhagen interview

Brian Rasmussen has just posted an interview we did by email, as a sort of precursor to my talk in Copenhagen. It's nice to occasionally write down "where I am" in terms of my feelings about Java, C# and my own career. There's a bit...
