How do I decompile a .NET EXE into readable C# source code?

Learn how to decompile a .NET EXE into readable C# source code. Decomplication is the process used to produce source code from compiled code. However, you should be aware that if an application is a commercial / industrial application, the source code is usually obfuscated. An obfuscator tool simply replace some words with a bunch of nonsense, so it becomes unreadable to anyone who decompiles it.

Please do use this for educational purposes only. I am not responsible if you do illegal things with decompiler.

In my video, I am using dotPeek from JetBrains, but there are many other decompiler our there. These are some of the popular decompiler.
- Dotnet IL Editor (DILE)
- JetBrains dotPeek
- NET CodeReflect
- RedGate Reflector
- telerik JustDecompile
- IL.View
- ILSpy
- ILDasm

Thank you so so much for this video - It SAVED me. I literally prayed for you. One of my most important semester final project files got corrupted and I got it back by decompiling the .exe generated by VS. i hope you are doing well and happiness finds you wherever you are. God BLESS

Hello,
Do you do freelance work?
I’m looking for help with a plugin (DLL I think) - it would be a simple change inside the plugin to change a single data field.

Cómo puedo ver el código de programación de un archivo ".exe"? He descargado "dotPeek" y no logro poder ver el código de programación del archivo que quiero, sólo me deja ver muchos archivos pero no lo que yo realmente necesito...
Lo necesito para un Bot de Trading, que tiene una API de otra persona, necesito cambiarlo para poner mi API. Para eso quería descompilarlo. Gracias y Saludos cordiales desde Argentina!

Dragged my application into DotPeek and it said not supported on the right side of the application name? What do I do now? Should I unpack it then decompile it, edit it, then recompile it or?
