C# 使用Spring.NET 实现 IOC控制反转,DI依赖注入

导入Common.Logging,Spring.Core

创建用户信息业务接口类：

IUserInfoService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SpringNet
{
   public  interface IUserInfoService
    {
      
        string ShowMsg();
    }
}

实现接口：

UserInfoService.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SpringNet
{
    class UserInfoService : IUserInfoService
    {

      public   string UserName { get; set; }
        public Person person { get; set; }
        public string ShowMsg()
        {
            return "Hello World!"+UserName+"年龄是:"+person.Age;
        }
    }
}

Person.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SpringNet
{
    public  class Person
    {
        private int age;
        private string name;

        public int Age { get => age; set => age = value; }
        public string Name { get => name; set => name = value; }
    }
}

配置App.config

  
    
      

      

    
  
  
    
      
         
    
    
      An  example that demonstrates simple IoC features.
   
    
  

Services.xml

  An  example that demonstrates simple IoC features.
  
  

需要设置xml文件属性为 复制到输出目录。

关键代码：

IApplicationContext ctx = ContextRegistry.GetContext();
            IUserInfoService lister = (IUserInfoService)ctx.GetObject("UserInfoService");
            MessageBox.Show(lister.ShowMsg());
