Question

就像标题所示，我有一个小程序，过去3个月一直在生产。上周，它开始在AddRange行上出错，并显示以下错误消息：

＆＃34;消息=不支持关键字：＆＃39;文件＆＃39;。＆＃34;

内部异常中没有任何内容。这是违规函数，我无法再访问SaveChanges()行。

private static void SaveToDB(List<MarketNew> inMarketNews) 
{

    proxy.MarketNews.AddRange(inMarketNews);
    proxy.SaveChanges();
}

欢呼声鲍勃

编辑 - 如果我尝试一次手动添加一个，我仍会收到以下异常。

Answer 1

该异常表示您的连接字符串存在问题。虽然程序本身可能在几个月内没有更改，但您能否确认配置文件（或者您设置的连接字符串）是否未更改？

如果您仍然无法从中找到它，我建议您在运行时检查连接字符串的值（例如，在AddRange行上放置一个断点，然后查看proxy.Database.ConnectionString）。我怀疑你会在连接字符串中找到“file”关键字。
