分配对变量的引用 [英] Assigning a reference to a variable
问题描述
如果我有一个结构,例如:
struct Settings {
public string str;
public double doub1 ,doub2;
public int i1;
}
如何将i1的引用分配给变量?我可以通过将它作为ref int
传递给函数来轻松完成此操作,但有没有办法将它传递给函数?

你可以使用不安全的代码来做,但我不建议这样做。如果您使用不安全的代码,则语法与C ++非常相似。
设置集=新设置();
sets.i1 = 5;
int * x =& sets.i1;
* x = 6;
控制台.WriteLine(sets.i1.ToString());

谢谢你的支持回复Jon + Tom。
我来自C背景,但我真的不想使用不安全的代码。

with。如何将整数作为引用类型?

If I have a structure, for example:
struct Settings{
public string str;
public double doub1, doub2;
public int i1;
}
How do I assign the reference of i1 to a variable? I can easily do this by passing it as a ref int
to a function, but is there a way to do this without passing it to a function?

make it a reference type to start with.

use unsafe code, the syntax is very similar to C++.
Settings sets = new Settings();
sets.i1 = 5;
int *x = &sets.i1;
*x = 6;
Console.WriteLine(sets.i1.ToString());

Thanks for your replies Jon + Tom.
I''m from a C background, but I don''t really want to use unsafe code.
"If you want a type to behave like a reference type, you should make it a reference type to start
with." How do I make an integer a reference type?
