Retrieve C# code out of EXE Assembly

31 Jul

I lost some of my applications code coz of PC format, one of these applications is a C# Console Application, I managed to get the exe output of this application but I was not able to retrieve the code files so I used (.NET Reflector) to do this:

 

1-     Download the .NET Reflector.

 

2-     Download the Reflector.FileDisassembler.

 

3-     Extract the .Net Reflector

 

4-     Extract the Reflecter.FileDisaembler

 

5-     Copy the Reflector.FileDisassembler.dll to the .Net Relector Folder

 

6-     Start Relector.EXE

 

7-     From the View menu select Add-Ins

 

 

8-     In the Add-Ins Screen select Add and select Reflector.FileDisassembler.dll then close the Add-Ins screen

 

 

9-     From File menu select Open and select the exe file you want to retrieve its code

 

 

10- The reflector will load the file Assembly in the Assemblies section

 

 

11- Select the required file and from the Tools menu select File Disassembler

 

null

 

12- Click Generate and you will get your code

 

null

 

 Finally I would like to thank Siderite for his help

    Hi I do not think it will work… it will only return back to you the source of the dll files.. Let us know if it worked for the aspx pages

    Hi,
    This post is a great post for all the young freshers.
    But i have one problem, i could not get the designer form after decompiling. The visual studio gives various errors when opened.
    Please look into this issue and help me in resolving the same.

      Thanks a lot for putting together this wonderful step by step guide. It help me recover the source to a program that i lost due to a system crash. However I also ran into similar difficulties when loading the Windows Forms Application in the designer as mention by Aseem above but manage to resolve the problem with the following steps:

      1. In the InitializeComponent method all references to windows components and enums need to be following qualified with the assembly name otherwise the designer is not able to load the form. For example instead of ComponentResourceManager manager use System.ComponentModel.ComponentResourceManager manager and instead of AutoScaleMode.Font use System.Windows.Forms.AutoScaleMode.Font etc.

      2. My system would not accept the name manager for ComponentResourceManager it keeps coming out with errors. I renamed it to resources instead.

      I hope it helps.
