有没有存储在一个类对象引用的方法吗？是这样的：

Is there a way to store a reference in a class object? Something like:

public class X
{
  public X(ref int i)
  {
    _t = i;
  }

  public void f(int ii)
  {
    _i = ii;
  }

  private int ref _i;
}

// ...
int i = 0;
X x = new X(ref i);
x.f(42);
// i is now 42

在C ++中我会用指针或引用做到这一点。

In C++ I'd do this with pointers or references.

推荐答案

您可以与非托管代码做到这一点，但没有一个托管代码的方式有一个值类型的引用。你不得不手动将其框变成某种对象容器，并有一个参考。

You can do it with unmanaged code, but there isn't a managed code way to have a reference to a value type. You'd have to manually box it into some kind of object container and have a reference to that.
