当我写一个类，我总是通过一个公共属性像这样公开​​私有字段：

When I write a class I always expose private fields through a public property like this:

private int _MyField;
public int MyField
{ get{return _MyField; }

当那是正确的，只是公开公共领域是这样的：

When is it ok to just expose a public field like this:

public int MyField;

我创建了一个名为结果结构，我的意思是这样做：

I am creating a structure called Result and my intention is do this:

public Result(bool result, string message)
{
   Result = result;
   Message = message;
}

public readonly int Result;
public readonly int Message;

什么是最好的做法是什么？是以往任何时候都好做呢？

What is the best practice? Is it ever ok to do this?

推荐答案

我只揭露公共领域时，他们（静态）常数 - 即使如此，我通常会使用属性

I only ever expose public fields when they're (static) constants - and even then I'd usually use a property.

通过恒定我的意思是任何只读，不可变的价值，而不只是其中一个可能是pssed在C＃中的常量EX $ P $。

By "constant" I mean any readonly, immutable value, not just one which may be expressed as a "const" in C#.

即使是只读的实例的变量（如结果和消息）应该被封装在我看来，一个属性。

Even readonly instance variables (like Result and Message) should be encapsulated in a property in my view.
