Data.linq上下文,列名无效



在DEV中的数据库表中添加了一个新列后,我更新了我的dbml文件。一切都在DEV环境中工作。但是,当部署到测试和生产时,我会得到"无效列名"异常。有什么建议吗?

var CreateUpdateCtx = new MyDataContext(connectionstring);
var Data = vutTable.Accounts.ToList(); //Calling ToList() results in the exception shown below

更新:添加日志:

异常消息:列名"MyNewAddedColumn"无效。

看起来您还没有将数据库更改从本地数据库或较低环境数据库转移到生产数据库。请核实。

所以,当您在dev中运行Linq2SQL时,它正在工作,因为本地或dev数据库中存在新列。但在生产中,DBML试图从Accounts表的新列中检索值,但它不存在,导致出现上述错误
