[英]C# How do I compare and exchange two structs?
I have the following program: 我有以下程序:
public class Program
{
struct Foo
{
public int Bar;
public int Zoo;
}
public static void Main()
{
Foo a;
Foo b;
a.Bar = 5;
a.Zoo = 2;
b.Bar = 5;
a.Zoo = 2;
Foo c;
c.Bar = 3;
c.Zoo = 5;
var result = Interlocked.CompareExchange(ref a, b, c);
}
}
How can I make this compile? 我该如何进行编译?
You can't, basically. 基本上你不能。 The framework doesn't provide a way of performing atomic, lock-free operations on arbitrary structs.
该框架没有提供对任意结构执行原子无锁操作的方法。
