View intermediate language (IL)

ReSharper | Windows | IL Viewer

To assign a shortcut, go to Tools | Options | Environment | Keyboard and find the ReSharper_ShowIlViewerWindow command.

ReSharper allows you to study your source code and decompiled symbols as intermediate language (IL) or as C# with different levels of syntax sugar.

note

The intermediate language for source code becomes available after you build your project.

If the source was modified after the build, the synchronization between the source and the IL code could be incorrect. The IL code will be updated as soon as you build the project again.

IL Viewer

When you open symbols from compiled assemblies, you can always study them in the intermediate language independently of their presentation in the editor. Even if the symbol is displayed in the original source file obtained through PDB, ReSharper will find the related piece of IL code for it.

View intermediate language (IL) for a symbol

  1. Do one of the following:

    • Choose ReSharper | Windows | IL Viewer from the main menu.

    • Right-click anywhere in the editor and choose Navigate | IL Code

    • Invoke Navigate To Alt0` and choose IL Code.

  2. ReSharper will display the IL code corresponding to the symbol in the IL Viewer window.

  3. While the IL Viewer window is open, the view is synchronized with the caret position in the editor and the matching code is highlighted. To change that, click Track Caret in Editor Track Caret in Editor on the toolbar of the IL Viewer.

ReSharper: Using IL Viewer

In the IL Viewer window, you can learn descriptions of IL instructions in tooltips when hovering over an instruction. The descriptions are taken from Microsoft Learn and from the ECMA-335 standard (Partition III: CIL Instruction Set).

When you place the caret at a code symbol or instruction, all usages of this item are highlighted. Loops in your code can be distinguished by corresponding indents and comments.
