c# - 用值定义结构数组

Question

我可以用值定义结构/类数组吗(如下所示)以及如何定义？

   struct RemoteDetector
    {
        public string Host;
        public int Port;
    }

    RemoteDetector oneDetector = new RemoteDetector() { "localhost", 999 };
    RemoteDetector[] remoteDetectors = {new RemoteDetector(){"localhost",999}};        

编辑:我应该在值之前使用变量名:

    RemoteDetector oneDetector = new RemoteDetector() { Host = "localhost", Port = 999 };
    RemoteDetector[] remoteDetectors = { new RemoteDetector() { Host = "localhost", Port = 999 } };

你可以这样做，但不推荐这样做，因为你的结构是可变的。您应该努力实现结构的不变性。因此，要设置的值应该通过构造函数传递，这在数组初始化中也很简单。

struct Foo
{
   public int Bar { get; private set; }
   public int Baz { get; private set; }

   public Foo(int bar, int baz) : this() 
   {
       Bar = bar;
       Baz = baz;
   }
}

...

Foo[] foos = new Foo[] { new Foo(1,2), new Foo(3,4) };
