在MVC控制器操作中获取Unity容器引用

using System.Web.Mvc;
using Unity;
using Unity.Mvc5;

namespace YourNamespace
{
    public class MvcApplication : System.Web.HttpApplication
    {
        public static IUnityContainer UnityContainer { get; set; }

        protected void Application_Start()
        {
            // 初始化Unity容器
            UnityContainer = new UnityContainer();

            // 注册依赖关系
            // UnityContainer.RegisterType<IYourInterface, YourImplementation>();

            // 其他MVC配置代码...

            // 启用Unity依赖注入
            DependencyResolver.SetResolver(new UnityDependencyResolver(UnityContainer));
        }
    }
}

using System.Web.Mvc;
using Unity;

namespace YourNamespace.Controllers
{
    public class YourController : Controller
    {
        private readonly IUnityContainer _unityContainer;

        public YourController(IUnityContainer unityContainer)
        {
            _unityContainer = unityContainer;
        }

        // 控制器操作代码...
    }
}
