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
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,后者又来自。
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.
