做仿函数都在C＃中的等价？ [英] Do functors have an equivalent in C#?

问题描述

？

有一个相当于函子在C＃

C＃有Func键<，>，代表和匿名方法，但并非所有这些指针的方法？

C ++的仿函数是一个类，而不是一个指针的方法。

解决方案

C＃有Func键<，>，代表和匿名方法的但不所有这些指针的方法？

$乙
$ b

没有。即使是C＃委托是类，编译器为你实现。这些生成的类（代表）从 MulticastDelegate 反过来从 代表 。

总之，委托是由编译器生成的类的语法糖。

Is there an equivalent to Functors in C#?

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

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

解决方案

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

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.

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