Question

我正在尝试将asp.net应用程序部署到Windows Server 2012服务器，并遇到了一个问题，即应用程序将不再连接到SQL Server 2012上的localdb服务器。我可以访问localdb数据库Microsoft SQL Server Management Studio，数据库资源管理器将连接，我将连接属性中的连接字符串复制到Web.Config文件中，用实际密码替换星号。即使连接是可能的，我仍然无法连接它。

Web.Config中的连接字符串（用实际值替换用户ID和密码）是：

<add name="ApplicationServices" 
     connectionString="Data Source=(localdb)\v11.0;Initial Catalog=Grouplink;Integrated Security=False;User ID=******;Password=*********;" 
     providerName="System.Data.SqlClient" />

例外情况如下：

System.Data.SqlClient.SqlException was caught
  Class=14
  ErrorCode=-2146232060
  HResult=-2146232060
  LineNumber=65536
  Message=Login failed for user 'sa'.
  Number=18456
  Procedure=""
  Server=(localdb)\v11.0
  Source=.Net SqlClient Data Provider
  State=1

  InnerException:

该应用程序在开发系统上工作，因此我不知道为什么代码不起作用，而其他访问方法确实有效。尝试打开连接时发生异常。

Answer 1

看起来像localdb \ v11.0在另一台计算机上不存在，替换＆＃34;（localdb）\ v11.0＆＃34;适用的＆＃34; {servername} {SQLServerInstanceName}＆＃34;在我的文本中没有花括号的连接字符串中。

部署localdb / v11.0时不再有效
