C#参考成员变量 [英] C# reference member variable
问题描述
在C#中，有没有一种方法可以将引用保留为对象中的成员变量(如C ++中的对象指针)，而不仅仅是保留为参数?
我如何才能使指针或对象引用作为成员变量?
How can I make a pointer or reference to an object as a member variable?
推荐答案
如果您的意思是 ref参数传递约定，那么不能，您不能存储它.从MSDN上的第一个注释起:
If you mean ref the argument passing convention, then no, you cannot store this. From the first note on MSDN:
不要混淆按引用传递的概念与引用类型的概念.这两个概念不一样...
Do not confuse the concept of passing by reference with the concept of reference types. The two concepts are not the same...
编辑:根据您更新的问题，C#在指针和引用方面有不同的命名法. C#中的指针是不安全有点的em>构造直接引用对象的内存位置.我之所以这么说是因为内存位置可以根据垃圾回收而改变(除非您将其修复在内存中).
Edit: based on your updated question, C# has different nomenclature about pointers and references. A pointer in C# is an unsafe construct used to somewhat directly reference the memory location of an object. I say somewhat because the memory location can change based on garbage collection (unless you fix it in memory).
引用是默认的引用类型传递并存储.它们类似于其他语言中的 pointers (指针)，但并不完全相同.但是，通过 by-reference 参数传递约定，您可以直接更改对象所指的内容.
References in C# are the default way reference types are passed and stored. They are akin to pointers in other languages, but not quite the same. However, the by-reference argument passing convention allows you to directly change what an object refers to.
如果您的目标是对非引用类型的局部变量保留可变引用，则必须将局部变量封装在
If your objective is to keep a mutable reference to a non-reference type local variable, you'll have to encapsulate the local variable in a reference type (like a class). If you could give some sample code, we can give some specific examples.
