内部在C＃与VB中的朋友 [英] Internal in C# vs. Friend in VB

问题描述

我正在尝试将一些代码从VB转换为C＃。我在VB中将朋友功能作为C＃中的内部功能。但是，与内部函数不同，可以在没有对象的情况下调用friend函数。所以，我将内部函数设置为静态，以便我可以使用类名称来调用它（类似于friend函数的工作方式）。我对此并不满意。有一个更好的方法吗 ？ A类和B类当然在同一个组件中。



我尝试过的方法：

 类 A {
 内部  void  function（）{ //  做某事}  
} 
  class  B {
  void  CallFunction（） {A.function（）;  //  不可能！ 
} 
}

VB的朋友相当于C＃的内部 - 它不允许您访问没有实例的方法只是使用任何一种语言的类名。要在VB中执行此操作，请指定共享 - 对于C＃，它是 static 。



我怀疑你的VB方法标记为朋友共享而不仅仅是朋友 - 其中允许他们实例免费访问，就像C＃内部静态方法一样。

I'm trying to convert some code from VB to C#. I made a "friend" function in VB as "internal" in C#. However, friend functions can be called without an object unlike internal functions. So, I made the internal function static so that I could call it using the class name (similar to how the friend function worked). I'm not very happy with this. Is there a better way to do this ? Classes A and B are in the same assembly of course.

What I have tried:

class A{
internal void function(){//do something}
}
class B{
void CallFunction(){A.function(); //not possible !
}
}

解决方案

Have a look at this chart. It will answer this and many other questions for you... VB.NET and C# Comparison[^] ... it helped me with my transition to C#.

VB's Friend is the equivalent of C#'s internal - it does not allow you to access the method without an instance just by using the class name in either language. To do that in VB, you specify Shared - for C# it's static.

I suspect that your VB methods are marked as Friend Shared rather than just Friend - which would allow them instance-free access, just like a C# internal static method.
