由于对象的当前状态，操作无效

问题描述

大家好，



我在c＃中有一个asp.net网络应用程序，

我从excel表中获取数据并通过数据表将其填入转发器中。



这个excel表包含650行和20列。



它正在获取所有记录并填写转发器。



但是当我试图将这些数据推送到服务器时，

我收到此错误

由于对象的当前状态，操作无效。

i已经在互联网上搜索了这个错误，我得到了一些解决方案。



我试过的地方，

< appSettings> 
< add key =aspnet：MaxHttpCollectionKeysvalue =5000/> 
< add key =aspnet：MaxJsonDeserializerMembersvalue =5000/> 
< add key =FolderPathvalue =Files //> 
< / appSettings> 

我仍​​然遇到同样的错误。



任何人都可以帮助我。





谢谢
