c# - C# 中空泛型参数 <,> 的术语是什么？

Question

可能重复：
C# 语言：泛型、打开/关闭、绑定/未绑定、构造

在 C# 中使用反射做一些事情时，我注意到某些类型具有类型定义，例如

Foo<,>

这个符号的官方术语是什么？

Answer 1

Type names which are missing generic parameters such as List<> are referred to as unbound generic types. This question has a good summary of unbound generic types as well as some related terminology.

Depending on what context you are describing these types, some other terminology may be used. The C# specification uses the term "unbound generic type" to refer to something like T<>. The .Net framework seems to prefer the terms "generic type definition" (as dasblinkenlight pointed out, see also Type.GetGenericTypeDefinition()) or "open generic type" (see this article).

Answer 2

This is a type that represents a generic type definition:

 var genType = typeof(Foo<int,int>);
 var genTypeDef = genType.GetGenericTypeDefinition(); // Returns typeof(Foo<,>)
