Question

我很难过，我想把我现有的azure数据库和脚手架用来为我的网站查询我的表格。每次运行此dnx命令时，都无法登录。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＆gt; 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

给出错误，我猜它与我的sql连接字符串有关，但我不知道是什么。

Answer 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

Question question = dbContext.Questions.Include("Answers.Replys.Member").Include("Answers.Stars.Member").SingleOrDefault(m => m.ID == Id);

右

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

Asp.net 5和EF7现有Azure数据库脚手架
