Question

我在生产服务器上托管了一个asp.net网站。

我在生成服务器上呈现控件时发生了asp.net错误。

此错误的堆栈跟踪是：

'/'应用程序中的服务器错误。你调用的对象是空的。描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪，以获取有关错误及其在代码中的起源位置的更多信息。

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

我已经完全测试了我的代码但是我找不到任何错误，因为相同的代码在登台服务器上运行正常。

我觉得这是一个错误，与生产服务器上的虚拟目录配置或asp.net配置相关联。

请帮助摆脱这个错误，因为它已经浪费了很多时间。

预先感谢，

我可能听起来多余。但请检查您是否拥有部署的ascx和/或aspx文件的最新版本。
