Unity2.0與interception的配合使用(EntLib5.0)

引用的命名空間如下：

建立一個協助類:

using Microsoft.Practices.Unity;
using Microsoft.Practices.Unity.Configuration;

/// <summary>
    /// 提供對UnityContainer的分裝
    /// </summary>
    public sealed class OB
    {
        private static IUnityContainer _Container = null;
        /// <summary>
        /// 需要在Web.config 或 app.config中設定unity
        /// </summary>
        public static IUnityContainer Container
        {
            get
            {
                if (_Container == null)
                {
                    InitContainer();
                }
                return _Container;
            }
        }
        public static T R<T>()
        {
            return Container.Resolve<T>();
        }
        private static void InitContainer()
        {
            if (_Container == null)
            {
                lock (typeof(OB))
                {

                    _Container = new UnityContainer();
                    _Container.LoadConfiguration();
                }
            }
        }
    }
