私有类公共方法？ [英] Private class with Public method?

问题描述

下面是一段代码：

private class myClass
{
   public static void Main()
   {

   }
}

        'or'

private class myClass
{
   public void method()
   {

   }
}

我知道，第一个将无法正常工作。而第二个会。

I know, first one will not work. And second one will.

但是为什么第一次不工作？是否有任何具体的原因是什么？

其实寻找这个角度来看的解决方案，这就是为什么使它大胆。对不起

Actually looking for a solution in this perspective, thats why made it bold. Sorry

推荐答案

这将是在这种情况下有意义的;你有一个公共类 SomeClass的，里面要封装了一些功能，只对 SomeClass的相关。您可以通过在 SomeClass的声明（在我的例子 SomePrivateClass ）的私有类，如下图所示做到这一点。

It would be meaningful in this scenario; you have a public class SomeClass, inside which you want to encapsulate some functionality that is only relevant to SomeClass. You could do this by declaring a private class (SomePrivateClass in my example) within SomeClass, as shown below.

public class SomeClass
{
    private class SomePrivateClass
    {
        public void DoSomething()
        {

        }
    }

    // Only SomeClass has access to SomePrivateClass,
    // and can access its public methods, properties etc
}

这无论 SomePrivateClass <中也是如此/ code>是静态，或者包含公共静态方法。

This holds true regardless of whether SomePrivateClass is static, or contains public static methods.

我称之为的嵌套类的，它是探索在其他的计算器线程。

I would call this a nested class, and it is explored in another StackOverflow thread.
