        public override List<KeyValue> GetExtEstoutBillSet()
        {
            return base.GetExtEstoutBillSet();
        }
    }
}

说明：

1.    代码编译后需要在批号捡货配置界面注册插件，插件注册字符串为二次开发插件的类全名，如：ClassLibrary1.Class,ClassLibrary1

2.    编写插件可以在插件方法中对捡货过程进行干预，也可以用于监视调试捡货过程，在这些方法中打上断点，跟踪调试可以看一下捡货的流程，以及执行过程中参数值，如果捡货没有完成也可以看一下是执行到哪一步之后出现问题不再继续执行
