哪一种是.net中速度更快的数据类型，还是c#中的数据类型呢? [英] which one is faster data types in .net or data types in c#?

问题描述

首先，您好，我很抱歉，因为我的母语不是英语我想了解哪种是更快的C#数据类型或.net数据类型我试图通过下面的代码理解，我认为.net数据类型更快(这是正确的吗?)我在x86和x64平台上都测试了这段代码

Hi to all first of all i am sorry because my first language is not english I want understand which one is faster C# data types or .net data types i try to understand by below code and i think .net data types is faster(is this correct?) i test this code both with x86 and x64 platform

            SW.Start();
            for (Int32 i = 0; i < 99999; i++)
            {
                for (Int32 j = 0; j < 999; j++)
                {
                    Int32 a = 37;
                    Int32 b = 37;
                    Double c = Math.Pow(a, b);
                    String d = "abcde";
                    String e = "abcde";
                    String f = d + e;
                }


            }
            Console.WriteLine(SW.Elapsed.TotalMilliseconds);
            SW.Stop();
            Console.ReadKey();

和我的第二个代码

  Stopwatch SW = new Stopwatch();
            SW.Start();
            for (int i = 0; i < 99999; i++)
            {
                for (int j = 0; j < 999; j++)
                {
                    int a = 37;
                    int b = 37;
                    double c = Math.Pow(a, b);
                    string d = "abcde";
                    string e = "abcde";
                    string f = d + e;
                }


            }
            Console.WriteLine(SW.Elapsed.TotalMilliseconds);
            SW.Stop();
            Console.ReadKey();

非常感谢

推荐答案

int 是 Int32 的别名. Int64 的 long .
