C＃3.0自动属性-是否有用？ [英] C# 3.0 auto-properties — useful or not?

问题描述

注意：这是在我开始C＃时发布的。凭借2014年的知识，我可以真正地说出自动属性是C＃语言有史以来最好的事情之一。

我习惯于创建自己的

private string title;
public string Title
{
    get { return title;  }
    set { title = value;  }
}

现在，使用。NET 3.0，我们获得了自动属性：

Now, with .NET 3.0, we got auto-properties:

public string Title { get; set; }

我知道这更是一个哲学/主观的问题，但是有没有理由使用这些自动-属性，而不是为每个字段保存五行代码？我个人的抱怨是这些属性对我隐藏了东西，我也不是黑魔法的忠实拥护者。

I know this is more a philosophical/subjective questions, but is there any reason to use these auto-properties except from saving five lines of code for each field? My personal gripe is that those properties are hiding stuff from me, and I am not a big fan of black magic.

实际上，隐藏的私有字段甚至不显示在调试器中进行设置，考虑到get / set函数不执行任何操作，这是可以的。但是，当我想实际实现一些getter / setter逻辑时，无论如何我都必须使用私有/公共对。

In fact, the hidden private field does not even show up in the debugger, which is OK given the fact that the get/set functions do nothing. But when I want to actually implement some getter/setter logic, I have to use the private/public pair anyway.

我看到了节省大量代码的好处。 （一对六行），而不会在以后失去更改getter / setter逻辑的能力，但是话又说回来，我已经可以通过简单地声明一个公共字段 Public string Title而无需使用{get;组; }块，从而节省更多代码。

I see the benefit that I save a lot of code (one vs six lines) without losing the ability to change the getter/setter logic later, but then again I can already do that by simply declaring a public field "Public string Title" without the need of the { get; set; } block, thus even saving more code.

那么，我在这里错过了什么？为什么有人实际上要使用自动属性？

So, what am I missing here? Why would anyone actually want to use auto-properties?

推荐答案

我们一直在Stack Overflow中使用它们。

We use them all the time in Stack Overflow.

您也可能对属性与公共变量。恕我直言，这确实是对它的反应，为此，它很棒。

You may also be interested in a discussion of Properties vs. Public Variables. IMHO that's really what this is a reaction to, and for that purpose, it's great.
