我是靠谱客的博主明理墨镜，最近开发中收集的这篇文章主要介绍【C#】结构体struct和类class的比较background1、Code2、Results3、Conclusion，觉得挺不错的，现在分享给大家，希望可以做个参考。

都知道sturct使用栈内存访问更快,class使用堆内存访问相对慢,为什么还会有class内使用struct的写法呢?

1、Code

using System.Diagnostics;

namespace BlogProject
{
    struct MyStructure
    {
        public string Name;
        public string Surname;
    }
    class MyClass
    {
        public string? Name;
        public string? Surname;
    }

    class MyMix
    {
        public MyStructure structure;
    }

    class Program
    {
        static void Main(string[] args)
        {

            MyStructure[] objStruct = new MyStructure[1000];
            MyClass[] objClass = new MyClass[1000];
            MyMix[] myMixes = new MyMix[1000];


            Stopwatch sw = new Stopwatch();
            sw.Start();
            for (int i = 0; i < 1000; i++)
            {
                objStruct[i] = new MyStructure();
                objStruct[i].Name = "Sourav";
                objStruct[i].Surname = "Kayal";
            }
            sw.Stop();
            Console.WriteLine("For Structure:- " + sw.ElapsedTicks);
            sw.Restart();

            for (int i = 0; i < 1000; i++)
            {
                objClass[i] = new MyClass();
                objClass[i].Name = "Sourav";
                objClass[i].Surname = "Kayal";
            }
            sw.Stop();
            Console.WriteLine("For Class:- " + sw.ElapsedTicks);


            sw.Restart();

            for (int i = 0; i < 1000; i++)
            {
                myMixes[i] = new MyMix();
                myMixes[i].structure.Name = "Sourav";
                myMixes[i].structure.Surname = "Kayal";
            }
            sw.Stop();
            Console.WriteLine("For Mixed:- " + sw.ElapsedTicks);
            Console.ReadLine();
        }
    }
}
