Question

我正在尝试将asp.net 4.5 mvc4应用程序部署到内部服务器。构建文件在服务器上，但尝试访问该站点会产生这些错误：

我认为它与我的连接字符串有关：

<add name="MyDatabase" connectionString="data source=Server;initial 
catalog=MyDatabase;User Id=App;Password=some password;"
providerName="System.Data.SqlClient"/>

思想

Answer 1

好的，问题是UsersContext仍在使用默认连接字符串。我只需要将基本上下文更改为我的连接字符串。

public class UsersContext : DbContext
{
    public UsersContext()
        : base("MyDBContext")
    {
    }

    public DbSet<UserProfile> UserProfiles { get; set; }
    public DbSet<webpages_Membership> webpages_Memberships { get; set; }
    public DbSet<UsersInRole> webpages_UsersInRoles { get; set; }
    public DbSet<Role> webpages_Roles { get; set; }
}

请注意，我遇到了UsersContext表和我自己的连接字符串的超时问题。在使用此修复程序之前，您可能需要查看此主题： SimpleMembership MVC 4 stays authenticated, but is not authenticated

Answer 2

1）该服务器名称（服务器）是否正确？这是您在SQL Management Studio或Visual Studio中连接到它时看到的名称吗？ SQL Server的版本和版本是什么？

2）连接字符串参数是否在UDL文件中有效？

3）检查连接字符串是否符合预期。我在下面提供了一个使用log4.net记录连接字符串的示例，但您可以在那里放置断点或写入文本文件。

m_log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType );
foreach( var connectionString in System.Configuration.ConfigurationManager.ConnectionStrings )
{
    string outString = connectionString.ToString();
    m_log.Debug( outString );
}

Answer 3

我通过注释文件过滤器FilterConfig.cs InitializeSimpleMembershipAttribute中出现的行来解决了这个问题。我认为它必须执行codefirst我不使用，并且它连接到我在出版物中的文件。
