根据类名,动态创建实例的问题,谢谢

[kewnr9]

Assembly a = Assembly.LoadFrom("xxx.dll");
Type type = a.GetType("class name");

type为null,生成不了一个实例,但是dll和类都存在的,请问这是什么问题呢?谢谢.

给你一个例子

        #region public String LoadConnectionString(String NetWorkCategory) // 获取连接字符串
        /// <summary>
        /// 获取连接字符串
        /// </summary>
        /// <param name="NetWorkCategory">网络类型</param>
        /// <returns>连接字符串</returns>
        public String LoadConnectionString(Consts.NETWORKCATEGORY NetWorkCategory)
        {
           Assembly Ass = Assembly.LoadFrom(GetCurrentFullPath() + "DSMT.Extra.dll");
            Type AssType = Ass.GetType("DSMT.Extra.Special");
            Object Obj = Activator.CreateInstance(AssType);
            MethodInfo MI = AssType.GetMethod("GetConnectionString");
            MethodInfo MI2 = AssType.GetMethod("Make");
            return MI2.Invoke(Obj, new Object[] { MI.Invoke(Obj, new Object[] { NetWorkCategory }) }).ToString();
        }
        #endregion
