C＃不安全缺乏指针？ [英] Unsafe lack of pointers in C#?

问题描述

很抱歉，如果这很明显，但我会问...


有没有一种在C＃中使用指针操作的新方法？


我有一本关于C＃的Deitel书，它没有提到指针这个词。也不是

不安全在索引中。


来自C / C ++世界，指针非常有意义，并且在CS上达到
的速度，指针消失了吗？


要编译，必须通知编译器该段是不安全的。 ？


多数民众赞成好吧，我可以强迫不安全/指针，但是有更新，更好的方法吗？

Sorry if this is obvious, but Ill ask...

Is there a new way of using pointer operations in C# ?

Ive got a Deitel book on C# that neither mentions the word "pointer" nor
"unsafe" in the index.

coming from a C/C++ world, pointers make perfect sense, and getting up to
speed on CS, did pointers go away?

To compile, one must inform the compiler the segment is "unsafe" ?

Thats okay, I can force unsafe/pointers, but is there a newer, better way??

推荐答案

在C ++中，指针是从

程序编程时代开始实现的一种方式。你不需要它们在C＃中。使用OO结构

。


你能给我一个例子，说明你会认为指针是什么？
好东西，所以我可以用

OO方法给你一些如何做到这一点的想法？

In C++, pointers were a way of implementing things from the days of
procedural programming. You don''t need them in C#. Use OO constructs
instead.

Can you give me an example of a situation where you''d think pointers are a
good thing, so I can give you some ideas of how to do this differently using
OO methods?

嘿谢谢，这是有道理的，但它只是发生在指针上......


我有一个例子，我偶然发现了它


班级门票{

私人旅客*旅行者;

}


班级乘客{


私人清单< Ticket>门票;


}


等级座位{


私人乘客*乘客;

}


我确定有一个流行语可以做到这一点，当我听到

它是什么时我会感到愚蠢但是当我试图把它扔进我的C＃代码时，它抱怨并且

说不，你必须使用不安全。标记这种叛徒代码...

Hey thanks, that makes sense, but it just occured to me about pointers...

Ive got an example, where I stumbled into it

Class Ticket {
private Passenger *traveler;
}

Class Passenger {

private List<Ticket> tickets;

}

Class Seat {

private Passenger *occupant;

}

Im sure there is a buzzword for doing this, and Ill feel dumb when I hear
what it is, but when I tried to toss this into my C# code it complained and
said no, you must use "unsafe" to mark that kind of renegade code...
