BusinessFactory  在一个模块里 

代码 如下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using VotingSystemFrameWork.BusinessFactory;

using VotingSystemFrameWork.IBusiness;



namespace VotingSystem.BusinessFactory

{

    public class BusinessFactory : BusinessFactoryBase

    {

        /// <summary>

        /// 创建业务层对象

        /// </summary>

        /// <typeparam name="T">Biz的类型</typeparam>

        /// <param name="className">完全限定名</param>

        /// <returns>T</returns>

        public virtual T CreateBiz<T>(string className)

        {

            T t = CreateBizInstance<T>(className);

                           为什么t 会为 null           

             IBusinessBase iBusinessbase = (IBusinessBase)t;

            iBusinessbase.Init();

            return t;

        }

    }

}



BusinessFactoryBase 在 框架里的一个模块

代码如下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Reflection;



namespace VotingSystemFrameWork.BusinessFactory

{

    public class BusinessFactoryBase

    {

        /// <summary>

        /// 创建业务层对象

        /// </summary>

        /// <typeparam name="T">biz的类型</typeparam>

        /// <param name="className">完全限定名</param>

        /// <returns>T</returns>

        protected T CreateBizInstance<T>(string className)

        {

            Assembly assembly = Assembly.GetExecutingAssembly();

            return (T)assembly.CreateInstance(className);

        }    

    }

}
