C＃：具有“+”在类名中？ [英] C# : having a "+" in the class name?

问题描述

类名：MyAssembly.MyClass + MyOtherClass

class name: MyAssembly.MyClass+MyOtherClass

问题显然是+作为分隔符，而不是传统的点，其功能，如果其他分隔符存在

The problem is obviously the + as separator, instead of traditionnal dot, its function, and to find official documentation to see if others separators exist

提前感谢！

推荐答案

只是表示嵌套类型的方式。例如：

That's just the way that a nested type is represented. So for example:

namespace Foo
{
    class Outer
    {
        class Nested {}
    }
}

将创建一个类型为full在编译的代码中的 Foo.Outer + Nested 的名称。 （这就是 typeof（Outer.Nested）.FullName 会返回，例如。）

will create a type with a full name of Foo.Outer+Nested in the compiled code. (So that's what typeof(Outer.Nested).FullName would return, for example.)

对我来说，这是否是指定的行为，或只是微软的C＃编译器选择使用;它是一个不可言说的名称，你不能在正常的C＃中显式声明一个带有+的类，所以编译器知道它不会与任何其他冲突。

It's not clear to me whether this is specified behaviour, or just what the Microsoft C# compiler chooses to use; it's an "unspeakable" name in that you couldn't explicitly declare a class with a + in it in normal C#, so the compiler knows it won't clash with anything else. Section 10.3.8 of the C# 3 spec doesn't dictate the compiled name as far as I can see.

编辑：我刚刚看到， Type.AssemblyQualifiedName 指定+用于嵌套类型名称之前...但仍然不清楚是否实际需要 或仅仅是常规。

I've just seen that Type.AssemblyQualifiedName specifies that "+" is used to precede a nested type name... but it's still not clear whether or not that's actually required or just conventional.
