在动态引用DLL-A中，当参数是个实体，而实体的属性在另一个DLL-B中。。我们需要得到A这个实体并将其赋值，并将赋值的实体传人DLL-A的方法中。

  string strPath = HttpContext.Current.Server.MapPath("/开放式DLL");
                DirectoryInfo df = new DirectoryInfo(strPath);
                System.IO.FileInfo[] fr = df.GetFiles();
                    foreach (System.IO.FileInfo f in fr)
                {
                    if (f.Name.EndsWith("CNKI_Mngr.dll"))
                    {
                        System.Reflection.Assembly Mngrass = System.Reflection.Assembly.LoadFrom(f.FullName);//加载程序集

                        Type cnkiStructtp = Mngrass.GetType("CNKI_Mngr.UserStruct");//获取程序集中的实体对象
                        Type cnkiBasetp = Mngrass.GetType("CNKI_Mngr.UserBaseInfo");
                        Type cnkiComtp = Mngrass.GetType("CNKI_Mngr.UserComInfo");
                        object obj1 = System.Activator.CreateInstance(cnkiStructtp);//创建实例
                        object obj2 = System.Activator.CreateInstance(cnkiBasetp);
                        object obj3 = System.Activator.CreateInstance(cnkiComtp);
                        FieldInfo[] BaseInfo = cnkiBasetp.GetFields();//获取创建的实例的所有属性
                        FieldInfo[] ComInfo = cnkiComtp.GetFields();
                        FieldInfo[] StructInfo = cnkiStructtp.GetFields();

                        BaseInfo[1].SetValue(obj2, enty.UserName);//对指定的属性就行赋值
                        BaseInfo[11].SetValue(obj2, enty.RealName);
                        BaseInfo[5].SetValue(obj2, enty.PassWord);
                        BaseInfo[13].SetValue(obj2, enty.Department);

                        ComInfo[2].SetValue(obj3, enty.EMail);
                        ComInfo[9].SetValue(obj3, enty.Phone);

                        StructInfo[0].SetValue(obj1, obj2);
                        StructInfo[1].SetValue(obj1, obj3);

                        foreach (System.IO.FileInfo item in fr)
                        {
                            if (item.Name.EndsWith("Grid30Register.dll"))
                            {
                                System.Reflection.Assembly ass = System.Reflection.Assembly.LoadFrom(item.FullName);
                                Type tp = ass.GetType("Grid30Register.CreateOperateClass");
                                MethodInfo meth = tp.GetMethod("PersonLibRegister");
                                object obj = System.Activator.CreateInstance(tp, new object[] { GridConfig.UserServerIP, GridConfig.UserServerIP, GridConfig.UserServerIP,
                                KbaseConfig.ServerIP, KbaseConfig.ServerUserName, KbaseConfig.ServerPsw, "", GridConfig.Language });
                                ReStr = meth.Invoke(obj, new object[] { us }).ToString();
                            }
                        }

                    }
