When exactly do I use a struct (Dont tell me when I want things to be allocated on a stack)

Question

A lot of times the answer is merely when I want things to be allocated on a stack instead of the heap.. assuming I dont know what the stack and the heap are (and please dont try to explain it here), when exactly should I be using structs instead of classes?

Here is the answer I've been giving out, but please tell me if I'm wrong or falling short of a better answer:

I create structs usually when I have enums that I want to add more data to. For instance, I might start with a simple enum:

public enum Colors { Blue, Green, Red }

Then if I need to store more aspects of this data I go to structs:

public struct Color
{
    string Name;
    int HexValue;
    string Description;
}

public class Colors
{
    public static Color Blue;
    public static Color Red;
    public static Color Green;
    static Colors()
    {
        Blue = new Color("Blue", 1234, "A light blue"
    }
}

重点是......类似于枚举,我只是在想要声明一堆类型时使用结构.

Answer 1

.NET中的struct vs class

使用结构的实际时间是你想要像属性这样的值类型.值类型与引用类型的行为有很大不同,如果您不了解,则差异可能会令人震惊并导致错误.例如,将结构复制到(和退出)方法调用中.

堆栈与堆栈对我来说不是一个令人信服的论据.在典型的.NET应用程序中,您经常关心对象的位置？

我很少在.NET应用程序中使用结构.我真正使用它们的唯一地方是在一个游戏中,我想要值类型,如矢量等对象的属性.

C++中的struct vs class

这是一个更简单的问题.C++中的结构和类彼此相同,只有一个小的区别.默认情况下,C++结构中的所有内容都是公共的,因为默认情况下,C++类中的所有内容都是私有的.这是唯一的区别.
