没有类型的对象初始化时叫什么？

Question

我只遇到过几次，还不是很了解，但我觉得有必要研究一下幕后到底发生了什么。

我知道它正在创建一个对象的新实例，但尚未指定类型。

var myObject = new {
    SomeProperty = "ABC",
    SomeOtherProperty = true
};

当您将 var 换成 object 或 dynamic 时，它也有效。但是，考虑到这一点，我真的找不到它的名字来研究它。我相信它被称为 pseudo-class 或 pseudo-object，但我找不到任何关于它的实际文档。

我已经对该主题进行了多次 Google 搜索 (here's the latest), and even reviewed a few related SO posts (here's one about initialization)，但我仍然没有找到答案。

这实际上叫什么？

Answer 1

这叫做Anonymous Type。

来自文档：

Anonymous types provide a convenient way to encapsulate a set of read-only properties into a single object without having to explicitly define a type first. The type name is generated by the compiler and is not available at the source code level. The type of each property is inferred by the compiler.

Answer 2

它被称为一个anonymous type，它被直接实例化了。

Instantiation of anonymous types

To create an instance of an anonymous type, use the new operator and object initializer syntax:
var example = new { Greeting = "Hello", Name = "World" };
Console.WriteLine($"{example.Greeting}, {example.Name}!");
