实现代码

  
  
void Main()

{

    IUnityContainer container = 
   
   new UnityContainer();

    UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection(
   
   unity
   
   ");

    section.Containers.Default.Configure(container);

 

    sqlHelp sqlHelp = container.Resolve<sqlHelp>();

    Console.WriteLine(sqlHelp.sqlConnection());

}
  
  

运行结果:

my sql connection
