Question

Sometimes I would like to quickly see the IL representation of my code snippets in C#, to understand what exactly happens to various code statements under the hood, like it’s done here for example.

I know there are ildasm, Reflector, ILSpy, dotPeek and probably quite some other tools available. What I’m wondering here is that if there is any more elegant way from writing some lines of code to seeing the corresponding IL, than compiling your .net code, loading the assembly into one of those programs and finding the code you are curious about.

Maybe having a plugin for visual studio, which would add a right click option for “build and see IL code” or any other convenient way?

Edit:

After some more googling I found NDasm codeplex project which does what I was looking for – integrates into visual studio.

But vcsjones’ LINQPad suggestion is great as well, thus I am marking it as accepted, thanks. A really useful tool …

Answer 1

I typically use LINQPad for that. Just paste in some C# and switch to the IL view. For example:

I like it because you can also just post expressions or statements instead of a full program:

Best of all, it’s free (with optional premium features).
