Strange Runtime Error after obfuscation

Question

We have a assembly called DataObjectJsonLoader. Inside it there is an class as following:

 public static class DrillingFluidDataObjectJsonLoader
 {
     public static  Result<DrillingFluid> Load(string strDrillingFluid)
     {
        ....
        var type = ConvertToMudType(...);
        ....
     } 
     private static  MudType ConvertToMudType(string strDillingFluidType)
     {
      ....
     }     
 }

Everything works fine before obfuscation. The obfuscator we use is Net Reactor 5.0. And we already disable string encryption. But after obfuscation, when we call the above public function, there will be a runtime binder exception:

the 'DrillingFluidDataObjectJsonLoader' does not contain a definition for 'ConvertToMudType'.

What is the root cause of this problem? And how to fix it?

Answer 1

Maybe just exclude this class from obfuscation as a temporal solution...

  [Obfuscation(Exclude = true, ApplyToMembers = true)]
