c# - Different levels of access to methods -



c# - Different levels of access to methods -

situation:

i'm creating 2 libraries: x1.dll , x2.dll. created , amended separately , projects couldn't combined 1 solution.

x1.dll contains definition of class c1. x2.dll contains definition of class c2.

x2.dll references x1.dll.

class c1 has method m1(). method used in x2.dll , reason why m1() made public method.

i distribute x1.dll , x2.dll other developers. not want them phone call m1() - can whatever want c1 instances, not touch m1(). @ same time, m1() public because have able phone call in x2.dll.

question:

what best way organize m1() in order create available me still not merge projects x1.dll , x2.dll?

there plenty of awkward solutions making m1() m1(string secretecode) , hardcode secretecode i'm 1 can pass right argument.

but best practice accomplish goal?

thanks suggestions!

make m1() internal , add together internalsvisibletoattribute on assembly allow x2.dll phone call x1.dll's internal code. solution makes all internal code in x1 visible in x2, you're sure no 1 else going phone call m1().

from documentation:

ordinarily, types , members internal scope (in c#) , friend scope (in visual basic) visible in assembly in defined. internalsvisibletoattribute attribute makes them visible types in specified assembly, known friend assembly.

simply add together [assembly:internalsvisibleto("x2")] assembly. if assembly signed, you'll need add together public key of strong name key [assembly:internalsvisibleto("x2, publickey=0000000000")]

this improve "secret code" because c# code easy decompile , secret won't secret long time!

c# .net
