Question

尝试使用SimpleMembership初始化数据库连接时收到此错误消息。第一个初始化语句通过，而第二个初始化语句没有。目标是在运行Azure模拟器或部署时使用Azure服务配置中定义的连接字符串。

的Web.config：

<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-**********;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-**********.mdf" providerName="System.Data.SqlClient" />
</connectionStrings>

Azure .cscfg配置文件：

<Setting name="SqlConnectionString" value="Server=Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-********;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-********.mdf" />

SimpleMembershipInitializer：

string connectionStringName = "DefaultConnection";
string connectionString = CloudConfigurationManager.GetSetting("SqlConnectionString");
const string userTableName = "UserProfile";
const string providerName = "System.Data.SqlClient";
const string userIdColumn = "UserId";
const string userNameColumn = "UserName";

// This works fine.
// WebSecurity.InitializeDatabaseConnection(connectionStringName, userTableName, userIdColumn, userNameColumn, autoCreateTables: true);

// This throws exception.
// WebSecurity.InitializeDatabaseConnection(connectionString, providerName, userTableName, userIdColumn, userNameColumn, autoCreateTables: true);

环境：Visual Studio 2012，EntityFramework 5.0和MVC4 RTM，默认的SimpleMembership结构。

Answer 1

在我看来，您可能会遇到缺少双重逃避（\\v11.0而不是\v11.0），如this post中所述。

Answer 2

我很惭愧地意识到我的连接字符串中有拼写错误。我从Azure部署配置文件中获取连接字符串，例如：

<Setting name="SqlConnectionString" value="Server=Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-********;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-********.mdf" />

此处包含错字，位于值字符串的开头。它一定是一个版权'n'的错误。

此字符串在Azure配置文件Local.cscfg和Cloud.cscfg中分别用于Azure模拟器和Azure部署，以及在web.config中用于在模拟器外部运行。错字只出现在Local.cscfg文件中，这使我在试图找出它在某些情况下不起作用的原因时非常困惑。此外，由于某种原因，错字很难让我发现。事后来看，我看不出我怎么也没有早点弄清楚这一点。

Answer 3

我还没有解决方案，但到目前为止，这是我自己的调查和理论：

我看了一下WebSecurity.InitializeDatabaseConnection（）的源代码，想想也许我发现了一个bug。它似乎没有设置DatabaseConnectionInfo.Type属性，默认为ConnectionStringName，这可以解释为什么它不喜欢我的连接字符串，因为它会将其解释为连接字符串名称。

WebSecurity类：

public static void InitializeDatabaseConnection(string connectionString, string providerName, string userTableName, string userIdColumn, string userNameColumn, bool autoCreateTables)
{
  WebSecurity.InitializeProviders(new DatabaseConnectionInfo()
  {
    ConnectionString = connectionString,
    ProviderName = providerName
  }, userTableName, userIdColumn, userNameColumn, autoCreateTables);
}

DatabaseConnectionInfo类：

public Database Connect()
{
  switch (this.Type)
  {
    case DatabaseConnectionInfo.ConnectionType.ConnectionStringName:
      return Database.Open(this.ConnectionStringName);
    case DatabaseConnectionInfo.ConnectionType.ConnectionString:
      return Database.OpenConnectionString(this.ConnectionString, this.ProviderName);
    default:
      return (Database) null;
  }
}

private enum ConnectionType
{
  ConnectionStringName,
  ConnectionString,
}

WebSecurity.InitializeDatabaseConnection上的键“attachdbfilename”的值无效
