c# - standard procedure WINAPI DllMain environment .Net dynamic loading dll -

prompt how can implement analog standard procedure winapi dllmain environment. net dynamic loading. dll

bool winapi dllmain (     in hinstance hinstdll,     in dword fdwreason,     in lpvoid lpvreserved   );

i want have method in c# library executed when loaded?

there's no direct equivalence this, however, can create static class (or @ least static constructor class) executed when class used first:

 public class mylibraryfactory  {      static mylibraryfactory()      {           // add static initializer code here.           // called when class first referenced or used.      }  } 

this constructor called before other method using class. there's no guarantee first thing called inside library, compiler ensures else executes inside library independent of class, won't notice difference.
