Obfuscation problem

sergey

Hi guys,

I am using SmartAssembly 5.5 to obfuscate my assembly and it seems an unexpected problem occurred: A few internal classes and enums is partially obfuscated - namespace and class name aren't changed after obfuscation, although their members in classes are obfuscated and the ones aren't obfuscated in enums. Nevertheless, other internal classes in my code were obfuscated normally. I cannot found any differences for these classes in source code. Could you explain me what is the reason of this problem?

namespace Html.Model
{
    internal enum TextVAlignType
    {
        Baseline,
        Bottom,
        Middle,
        Top,
        Sub,
        Super,
        TextBottom,
        TextTop
    }
}

or

internal class SupportClass { 
...
}

Here is my sa project

If you .ToString() an enum, the enum and its class won't get obfuscated.

I've made a post about it here, and also submitted the working example to SA.

Yes, it would seem that if at any point you have a call to Format, GetName, GetNames, Parse, or ToString on an Enum, SA decides to not obfuscate it
