它在C＃中不存在。
你可以接近内部关键词。在那个访问修饰符中，
同一个程序集中的每个类都相当于一个
friend，除了私有和受保护的成员仍然是
隐藏。你会用内部的您真正想要分享的成员。
或者，嵌套类可以访问包含类的
的私有成员。但恕我直言，如果
嵌套类作为嵌套类真的有意义，那只是一个合适的解决方案。我不会只用
来解决一些可访问性问题。

It doesn''t exist in C#.
You can come close with the "internal" keyword. In that access modifier,
every class within the same assembly would be equivalent to being a
"friend", except that private and protected members would still be
hidden. You''d use "internal" on the members that you really want to share.
Alternatively, nested classes have access to private members of the
containing class(es). But IMHO that''s only an appropriate solution if the
nested class really makes sense as a nested class. I wouldn''t use it just
to address some accessibility issue.

典型的C＃解决方案是将类放在相同的
汇编中并使用internal。可访问性。
与C ++朋友最相似的是如果他们使用
" internal"可访问性和不同的程序集，但
使用InternalsVisibleTo属性 - 请参阅：

The typical C# solution would be to put the classes in same
assembly and use "internal" accessibility.
The most similar to C++ friend would be if they use
"internal" accessibility and are in different assemblies, but
use the InternalsVisibleTo attribute - see details at:

这只限制了其他代码的百万行的可访问性
碰巧在同一个程序集中，这是一个弱约束至于
没有实际用途。
