Question

我正在使用实体数据模型连接到数据库。它在当地工作正常。当我将我的网站上传到服务器时，它会抛出以下错误：

Server Error in '/' Application.
Non-negative number required.
Parameter name: count
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Non-negative number required.
Parameter name: count

Source Error:

Line 14:             //Fill the Route collection here.
Line 15:             routes.Clear();
Line 16:             foreach (var page in context.PageInfos)

服务器上的数据库肯定具有与从原始的.bak文件（从中生成EDM）恢复的结构和数据完全相同的结构和数据。

对此的任何帮助将不胜感激。
