c# - Using the methods of a compressed .Net DLL without extract it to hard disk -

step 1: want compress of .net dll files (some built class libraries) zip or 7z , protect theme password, can manually utilities windows 7z application.

the project files before applying scenario:

• app.exe
• a.dll
• b.dll

the final files after applying first step of scenario:

• app.exe
• x.zip (password protected & compressed archive file)

and x.zip contain a.dll & b.dll

---

step 2: now, want know there way extract a.dll & b.dll directly ram (not hdd) , use methods app.exe???

i want keep these dll files secure during scenario , prevent copy theme hdd users, want use functionalists after loading theme ram.

---

edit:

i usualy use these technologies: c#, wpf, .net 4.5

i think can use appdomain.assemblyresolve event.

when assemblies requested, extract them zip in memory byte array. use assembly.load(byte[]) overload load assembly in-memory byte array, , return assembly.
