问题描述

我喜欢使用结构很多。

所以在阅读这个文章,有什么其他问题我应该反对使用它们吗?

So after reading this article, are there any other concerns I should have against using them all the time?


  • When should I use a struct instead of a class?
  • When to use struct in C#?


推荐答案

您应该对结构进行以下考虑:

You should make the following considerations about structs:


  • 结构应该是不可变的(可变结构不直观和不可预测)

  • structs 始终具有无法更改的默认(public parameterless)构造函数

  • 结构大小不能超过16字节

  • 等于 GetHashCode 方法应该被覆盖以获得更好的性能

  • 实现 IEquatable< T> 界面建议

  • 重新定义和 == != 运算符也被推荐

  • structs should be immutable (mutable structs are not intuitive and unpredictable)
  • structs always have a default (public parameterless) constructor that cannot be changed
  • struct size should not exceed 16 bytes
  • the Equals and GetHashCode methods should be overriden for better performance
  • implementing the IEquatable<T> interface is recommended
  • redefining and == and the != operators is also recommended
