c# - 多重赋值(字段=属性=值)

Question

在 C# 中这样做安全吗？

field = Property = value;

是否保证setter和getter是连续调用的，field只赋给getter的结果，不一定是value？编译器会将其优化为仅 value 吗？

Answer 1

使用

    private int tada;
    public int TADA
    {
        get
        {
            Console.WriteLine("GETTER");
            return tada;
        }
        set
        {
            Console.WriteLine("SETTER");
            tada = value;
        }
    }

和

        int s = TADA = 1;

我只将 SETTER 写入输出窗口，所以它似乎没有调用 getter。

You can even assign the same value to multiple variables, like this:

int a, b, c, d;

a = b = c = d = 5;

In this case, a, b, c, and d would all have the value 5. This works because the C# compiler performs the rightmost assignment first; that is, d = 5. That assignment itself returns a value, the value 5. The compiler then assigns that returned value to c. That second assignment also returns a value, and so on, until all the variables have been assigned.
