为什么C＃是不允许非成员函数像C ++ [英] Why C# is not allowing non-member functions like C++

问题描述

C＃不允许写非成员函数和每个方法应该是类的一部分。我想这是所有CLI语言的限制。可是我错了，我发现，C ++ / CLI支持非成员函数。当它被编译，编译器将使方法，一些不愿透露姓名的类的成员。

C# will not allow to write non-member functions and every method should be part of a class. I was thinking this as a restriction in all CLI languages. But I was wrong and I found that C++/CLI supports non-member functions. When it is compiled, compiler will make the method as member of some unnamed class.

下面是C ++ / CLI标准说，

Here is what C++/CLI standard says,

[注：非成员函数通过CLI视为一些不知名的类的成员;然而，在C ++ / CLI源$ C ​​$ C，这样的功能不能明确与类名合格。注完]

[Note: Non-member functions are treated by the CLI as members of some unnamed class; however, in C++/CLI source code, such functions cannot be qualified explicitly with that class name. end note]

非成员函数中的元数据编码是不确定的。 [注：这不会导致互操作性问题，因为这样的功能不能有公众知名度。注完]

The encoding of non-member functions in metadata is unspecified. [Note: This does not cause interop problems because such functions cannot have public visibility. end note]

所以我的问题是，为什么不C＃实现这样的事情？或者你觉得不应该有非成员函数和每个方法应该属于某个类？

So my question is why don't C# implement something like this? Or do you think there should not be non-member functions and every method should belong to some class?

我的观点是有非成员函数的支持，并有助于避免污染类的接口。

My opinion is to have non-member function support and it helps to avoid polluting class's interface.

任何想法..？
