}

如果我使用系统，我会收到以下错误：

Login failed for user 'sa'.

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.Data.SqlClient.SqlException: Login failed for user 'sa'.

Answer 1

只需更改以下内容

App_Web_client 使用系统；

到

using System;

Answer 2

这与数据库引擎迁移无关 - 这是导致应用程序出现故障的代码，因为它无法编译。查看错误消息和周围信息，有足够的信息来诊断和解决这个问题。也就是说，更正你的用法：App_Web_clientusing System; 是无效的。
