软件工程师在C＃中有同等学历吗？ [英] Do functors have an equivalent in C#?

问题描述

C＃中有Functors吗？

Is there an equivalent to Functors in C#?

C＃有Func<，>，委托和匿名方法，但不是这些指针都指向一个方法？

C# has Func<,>, delegates and anonymous methods but aren't all of these pointers to a method?

C ++ Functor是一个类，不是一个方法的指针。

The C++ Functor is a class and not a pointer to a method.

推荐答案

C＃有Func<，>，委托和匿名方法所有这些指向方法的指针？

否。即使C＃代理是类，由编译器为您实现。这些生成的类（对于代理）派生自 MulticastDelegate ，后者又来自 委托 。

No. Even C# delegates are classes, implemented by the compiler for you. These generated classes (for delegates) are derived from MulticastDelegate which in turn derives from Delegate.

简而言之，委托是一个由编译器生成的类的语法糖。

In short, a delegate is a syntactic sugar for a class generated by compiler.
