推荐答案

您是否可以发布您收到的服务器错误？错误应该告诉你什么对象是null。

Could you post the server error you are receiving? The error should tell you what object is null.

这是错误：


对象引用未设置为对象的实例


此外我试图捕获错误但捕获得到Nothing：_（

This is the error :

Object reference not set to an instance of an object

Also i tried to catch the error but the catch got Nothing :_(

你设置了断点并逐步执行代码？

Did you set breakpoints and step through your code?
