asp.net-mvc – System.Data.SqlClient.SqlException：无效的对象名称’dbo.Projects’

我的MVC应用程序在尝试访问数据库中的任何表时返回sqlExceptions.

异常详细信息：System.Data.sqlClient.sqlException：无效的对象名称“dbo.Projects”.

我的应用程序我们linq为数据层.

如果我使用旧的dll它工作正常(所以似乎不是一个问题的DB)只是这个最新的应用程序DLL,我已经上传.

解决方法

检查连接字符串中的初始目录参数.可能是您的代码正在为Projects对象查找错误的数据库.

例如,如果您具有数据库同步设置,只有主数据库表的一部分被传输,那么如果Linq to sql希望所有表都位于连接字符串指向的数据库中,则可能会遇到此错误.
