could obfuscated .Net C# Application be Decompiled? [closed]

Question

I have written a program in .net C# to encrypt some information.

To accomplish the task I used an array which contains confidential information.I need to know that is it possible to crack the exe.I mean can anybody get the array from the exe file.The array values are not shown in the application.I used community version of Dotfuscator which comes with Visual Studio.NET. All I want to know that is it possible to extract the exe to access the member variables used in it.. ??

Yes, it would be very easy to decompile the application. You might want to install and run Reflector (or a similar equivalent) and see what gets exposed. Fundamentally, if there's sensitive information embedded in the application, it can always be found.
