Asp.net 5 和 EF7 现有 Azure 数据库脚手架答案

【问题标题】：Asp.net 5 and EF7 existing Azure database scaffoldingAsp.net 5 和 EF7 现有 Azure 数据库脚手架

【问题描述】：

我很困惑，我想使用我现有的 azure 数据库并将其搭建起来，以便为我的网站查询我的表。每次我运行这个 dnx 命令时，它都会无法登录。我已经仔细检查了我的密码和用户名。我只是希望能够从我现有的数据库中生成代码来进行查询。

这是我根据文档使用的命令。

C:\Projects\WebApplication>dnx ef dbcontext scaffold "数据源 = tcp:random.database.windows.net,1433；数据库 = MyDatabase；用户 ID = Username@random；密码 = {my_password}；加密 = True ; TrustServerCertificate = True;" EntityFramework.MicrosoftSqlServer

给出的错误，我猜它与我的 sql 连接字符串有关，但我不知道是什么。

【问题讨论】：

在问题本身中发布相关错误，而不是图片。堆栈跟踪中的错误消息和相关行应该足够了。
谢谢，从现在开始我会这样做的。我发现了我的问题。 . .我只是个白痴。我在连接字符串中的 myPassword 周围留下了括号。 . .谢谢梅森，来自梅森的声音听起来很奇怪；）。

【解决方案1】：

无意中忘记删除 SQL 连接字符串中密码周围的大括号 {}。

错误

C:\Projects\WebApplication>dnx ef dbcontext scaffold "Data Source = tcp:random.database.windows.net,1433; Database = MyDatabase; User ID = Username@random; Password = {my_password}; Encrypt = True; TrustServerCertificate = True;" EntityFramework.MicrosoftSqlServer

对

C:\Projects\WebApplication>dnx ef dbcontext scaffold "Data Source = tcp:random.database.windows.net,1433; Database = MyDatabase; User ID = Username@random; Password = my_password; Encrypt = True; TrustServerCertificate = True;" EntityFramework.MicrosoftSqlServer
