在DLL C＃中访问单独的类

Question

im trying to access a few classes i have in a dll. below is my dll (utils) and the classes that im trying to access inside of it (delim). but the only thing that i can access and use in the utils dll is kb.cs. i have no access to mouse.cs or delim.cs. which are the two that im in need of using. here is how im trying to access it. i have it in references, as you can see on the right hand side of the image. and i also have "using utils;" in there

what am i doing wrong?

Answer 1

delim must be declared public for the class to be visable in other assemblies (dll's and exe's)

public class delim
{
   ...
}

Answer 2

默认情况下，类是internal类。这意味着您不能从类的程序集外部访问它。您需要将类public 。
