一、使用自带的IOC容器

参考自 https://www.cnblogs.com/dudu/p/5552293.html

1、添加程序包 Microsoft.Extensions.DependencyInjection

修改Program.cs

IServiceCollection services = new ServiceCollection();
//注入
services.AddTransient<IMemcachedClient, MemcachedClient>();
services.AddTransient<MyTest>();
//构建容器
IServiceProvider serviceProvider = services.BuildServiceProvider();

//调用业务
var myTest = serviceProvider.GetService<MyTest>();
myTest?.test();

MyTest.cs代码

internal class MyTest
    {
        private IMemcachedClient _memcachedClient;
　　　　　//构造函数注入
        public MyTest(IMemcachedClient memcachedClient) 
        {
            _memcachedClient = memcachedClient;
        }
        public void test()
        {
            DateTime datetime = _memcachedClient.getTime();
            Console.WriteLine(datetime);
        }
    }
