Class 程序集的实例化 ("new") 问题和 类

Class instantiation ("new") problems with assemblies and classes

我正在从事一个项目,该项目要求我仅通过 class 自己的程序集实例化 ("new") 一个 class,而不是其他程序集。这可能吗?

我尝试使用抽象,但这意味着我无法在任何地方实例化它。

示例: 以下到classes在同一个project/assembly.

public class Banana
{
    public Banana()
    {
        ...
    }
}

public class Food.
{
    public static Banana InstantiateBanana()
    {
        Banana banana = new Banana();//<=====How can you instantiate it inside the same assembly? I don't want other assemblies to instantiate it.
        ...
        return banana;
    }
}

我想通了!

public class Banana
{
    private Banana()
    {
        ...
    }

    public static Banana InstantiateBanana()
    {
        Banana banana = new Banana();//<=====How can you instantiate it inside this class? I don't want other assemblies to instantiate it.
        ...
        return banana;
    }
}

这应该有效。仅在其自己的 class 中实例化 Banana class,但不在其他 class 中实例化。我只需要一个私有构造函数和一个静态方法来实例化。
