接口编译 [英] Interface Compilation

问题描述

有关C#接口的快速问题.我想知道它们在编译和使用汇编方面有多精确.

Quick question regarding interfaces in C#. I was wondering how exactly they are compiled and used assembly wise.

我想象接口没有被编译成汇编.我认为接口定义是在编译时编译到类中的，因此接口本质上是一种高级语言概念.

I imagine interfaces are not compiled into assembly. I imagine that the interface definitions are compiled into the class at compile time, so interfaces are essentially a high level language concept.

有人可以告诉我我的想法是否正确吗?我已经得出了这个结论，因为我已经阅读到接口没有实例化，它们是它们自己的实体.但是，另一方面，我也读到它们是引用类型，这使我感到困惑，因为这表明它们已实例化?

Could someone please tell me if I am correct/incorrect in thinking this? I came to this conclusion as I have read that interfaces are not instantiated, they are their own entity. On the other hand however, I have also read that they are reference types which confuses me as that would suggest that they are instantiated?

非常感谢.

推荐答案

我只是反汇编了一个仅包含接口的小程序:

I just disassemble a small program containing just an interface:

public interface IFoo {
    void Foo();
}

这就是我得到的:

.class interface public auto ansi abstract IFoo {
    // method line 3
    .method public virtual hidebysig newslot abstract 
       instance default void Foo ()  cil managed 
    {
       // Method begins at RVA 0x0
    } // end of method IFoo::Foo
} // end of class IFoo

因此，如果按大会的意思是MSIL，那么答案是肯定的，它们被视为类.

So, if by Assembly you mean MSIL, the answer would be yes, they are treated like classes.
