c# - 类型的类型的(官方)术语是什么？

Question

我正在使用 Roslyn 编写一个应用程序来从语法和语义上分析 C# 源代码。对于正在分析的源代码中定义的每种类型，我想存储它是引用类型(类)、值类型(结构)还是接口(interface)。

类型的类型的适当/官方术语是什么？

例子:

class A
{
    //This type's type (A's type) is 'class' (i.e. a reference type).
}

Answer 1

如果您想知道官方名称，请查看官方来源:C# 语言规范。从那里引用(§1.3 类型和变量；强调我的):

There are two kinds of types in C#: value types and reference types. […]

C#’s value types are further divided into simple types, enum types, struct types, and nullable types, and C#’s reference types are further divided into class types, interface types, array types, and delegate types.

然后有一个表格将这些类型组描述为类别，还有这句话:

Five of C#’s categories of types are user-definable: class types, struct types, interface types, enum types, and delegate types.

尽管稍后(在 §4 类型中):

The types of the C# language are divided into two main categories: Value types and reference types.

总而言之，规范称它们为类型的类别，尽管该术语的用法不是很一致。
