autofac實現批量注入

 

 省略接口和類的實現，具體如上圖：

using Autofac;
using System;
using System.Linq;
using System.Reflection;
namespace autofacBatchResolver
{
class Program
{
static void Main(string[] args)
{
var builder = DependencyResolver();
using (var container = builder.Build())
{
IFunciton1 fun = container.Resolve<IFunciton1>();
IService service = container.Resolve<IService>();
Console.WriteLine(service.GetUsers());
Console.WriteLine(fun.GetName());
}
Console.ReadLine();
}
static ContainerBuilder DependencyResolver()
{
var builder = new ContainerBuilder();
Type basetype = typeof(IDependency); //獲取頂級接口類型
builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
.Where(t => basetype.IsAssignableFrom(t) && t.IsClass) //查詢繼承自頂級接口IDependency的實現類，如果沒有這句，則注冊所有當前運行環境中接口實現類
.AsImplementedInterfaces().InstancePerLifetimeScope();
return builder;

}
}
}
