實體數據模型System.ArgumentOutOfRangeException

Question

我正在使用實體數據模型連接到數據庫。它在當地很好地工作。當我上傳我的網站服務器時，它引發以下錯誤：

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) 
Line 17:    { 
Line 18:     //get the friendly URL

服務器上的數據庫肯定具有完全相同的結構和數據，因爲它是從原來的.bak文件（恢復從中電火花生成）。

對此的任何幫助將不勝感激。

爲了參考：這是由於我的託管服務提供商更改了我必須用來連接到SQL服務器的端口。與代碼無關。
