If you're using enum.ToString() that often, you're doing it wrong

Daniel Wertheim measured the performance of enum.ToString and found it to be 400x slower than using a comparable class with const’s. That’s a massive difference, and something that, in theory, might make you think otherwise about using an enum. But in practice… who cares? You shouldn’t

In a previous post I explained how to set up and use the built in dependency injection container in ASP.NET vNext. Today we’re going to look at setting up and using the popular Castle Windsor DI container. In order to use third party DI containers the MVC team

Writing your own Convert.ToBase64String in C#

Have you ever wondered what Base64 is? How it works? Why you need it? Have you ever wanted to write your own Base64 encoder? Well, my friend, you are in luck because that’s what we’re talking about today. To get started… What is Base64? Base64 is a common

Converting an int to a binary string in C#

The .NET Framework has a built in overload of Convert.ToString which takes 2 parameters: the int you want to convert and an int of the base you want to convert to. Utilizing this with base 2, you can print out the string representation of a number in binary, like

When doing string concatenation in C#, why don't you have to call ToString on non string variables?

To get the string representation of a variable, in this case we’ll use int, there is no implicit conversion from int to string so you can call the ToString method: string s = myInt; //INVALID!! string s = myInt.ToString(); // Valid! When concatenating with another string, though, you don’t have

I’m a big, big fan of the .NET Framework. I have always felt that the whole framework is a very well thought out, organized and incredibly stable environment. I thoroughly enjoy developing for it and know a lot of people who feel the same way. That’s when I

Fun times with string.join in C#

I had an interesting issue the other day at work regarding string.Join. I had overridden ToString in one of my classes to easily output values from the object, and this new ToString implementation was utilizing string.Join: class Data { public string One { get; set; } public string Two { get; set;

Avoid Commenting Your Code

When I’m answering questions on Stack Overflow, I see a lot of questions with code like this: // Convert our ciphertext into a byte array. byte[] cipherTextBytes = encryptedBytes; ... // Create uninitialized Rijndael encryption object. TripleDESCryptoServiceProvider symmetricKey = new TripleDESCryptoServiceProvider(); ... // Define memory stream which will be used to hold encrypted data. MemoryStream memoryStream
