c# - 这个 C# 片段是什么意思？

Question

struct MyStruct : int
{
   .../...
}

MSDN声明之后是已实现接口的:列表，但int对我来说这是一个非常奇怪的接口......

这可能是一种定义结构大小的方法吗？有点像位域？

It is illegal and means nothing whatsoever.

However! If by int you mean "an interface", then it means: "this is a value-type that implements an interface"

You can't, however, have an interface called int, since int is a reserved keyword. You would have to refer to that as @int in the C#.

看起来 Struct 实际上应该说 Enum，那么它就会有意义。

这里struct MyStruct : int不是一个接口，所以编译器会失败

如果你有 Resharper，它会在运行构建之前通过红色下划线来警告你

因为知识 int 是System.Int32的别名，它是一个结构
