Question

当我试图通过通用存储库获取模型值时，我有一个例外。

我试图遵循lambda表达式

var surveyUserParameters = unitOfWork.SurveyUserParameters.Get() .Where(x => x.SurveyId == surveyId && x.UserEmail == User.Identity.Name) .SingleOrDefault();'

问题是异常表示存在名为dbo.SurveyUserParameters1的无效对象。我的表名是dbo.SurveyUserParameters，并且appatino代码中没有办法存在模型，变量或名为dbo.SurveyUserParameters1的东西。我不知道发生了什么，我会得到你的帮助。

Answer 1

将ctrl + f放在整个解决方案上，然后查找SurveyUserParameters1。可能是你的模型以某种方式搞砸了。

尝试将其重命名为SurveyUserParameters，或从数据库重新生成模型。

相信我，它在某处:-)。

Answer 2

检查连接字符串是否有SurveyUserParameters1。然后改变它。如果没有，您可能会将db表的添加量增加一倍。检查一下。
