Topic: Read exe with a reflector

[David Hall]

I dont even know if this is possible, but if I have an exe that another employee wrote for me in C#, but lost the source files when his computer was upgraded, can anyone open it and create new source files?  Its a simple little app that deletes files over 2 weeks old off the server.

I think Kerry has posted some links in this forum re reflection app's and code converters.
A quick search brought up this -> http://www.remotesoft.com/salamander/
I think you can download a demo or even upload a file for testing that may get you out of trouble in the short term.

Yes you can ... use this one

David,
Per Daniel's link, The 'Reflector for .NET ' by Lutz Roeder is pretty good. I may have a look at Salamander too ..

Cool, I will check those out

The Reflector for .Net by Roeder is awesome!!
I opened my exe and got everything I wanted, changed a path, recompiled and its on its way

By the way, I also learned how to get reg values to make the job of updating easier.  Now I just edit a regkey to tell it what folder to check and delete from
