mono支持dotnet core了

mono支持.netcore了

  mono 4.8终于发正式版本了,新版本开始支持.net core了.

  2. 不直接安装,通过MSIExtractor.exe解压提取的方式
  3. 手动添加到系统环境Path变量中: F:\softwares\mono-4.8.0.495-x64-0\Mono\bin

测试并运行mono

mono -V
mono -V 查看mono版本

分别用.net core和mono对比一下性能

 先上图
.net core性能测试

mono性能测试

测试代码

ConsoleApp代码

using System;
using System.Text;

namespace ConsoleApp
{
    public class Program
    {
        //虽然.net core支持条件编译,但是无法区分是个环境运行
        //目前只能通过Mono.Runtime判断是否那个环境运行的
        public static bool isMono = Type.GetType("Mono.Runtime") != null;
        public static void Main(string[] args)
        {
            //.net core 输出中文,不指定环境的,会乱码
            if (!isMono)
            {
                Console.OutputEncoding = Encoding.UTF8;
            }

            StringConcat.test();

            Console.ReadKey();
        }
    }
}

StringConcat 测试工具类(宇内流云大哥做测试用的)

using System;

            get
            {
