我已经在我的桌面上安装了 MS Sql Server 2012 并尝试编写 ac# 程序来

将 DB 文件附加到 SQL Server 2012,而我正在执行抛出的程序错误消息

如下所述,你能帮我解决吗

下面是 MS SQL Server 2012 抛出的错误消息,

数据库文件(mdf 和 ldf)

使用下面的代码:

方法 :

AttachDb("sqlDb","[C:\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\sqlDb.mdf] [C:Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\sqlDb_log.ldf]");

错误信息 :

    80131501 Error: An exception occurred while executing a Transact-SQL statement or batch.
    From: Microsoft.SqlServer.ConnectionInfo
     at Microsoft.SqlServer.Management.Common.ServerConnection.ExecuteNonQuery(String sqlCommand, ExecutionTypes executionType)
        at Microsoft.SqlServer.Management.Common.ServerConnection.ExecuteNonQuery(StringCollection sqlCommands, ExecutionTypes executionType)
        at Microsoft.SqlServer.Management.Smo.ExecutionManager.ExecuteNonQuery(StringCollection queries)

        at Microsoft.SqlServer.Management.Smo.Server.AttachDatabase(String name, StringCollection files)
        at TestSMO.AttachDb(String dbname, String filelist) 

代码:

     static string instance = "";
     static string username = "";
     static string password = "";
     static string connection_timeout = "600";
     static string statement_timeout  = "3600";

    //create server connection object 
    static Server Connect()
    {
    ServerConnection conn = new ServerConnection();
    instance="sqlDbServer";
    if (instance.Length > 0)
        conn.ServerInstance = instance;

    if (username.Length > 0) {
        conn.LoginSecure = false;
        conn.Login = username;
        conn.Password = password;
    }

    conn.ConnectTimeout = Convert.ToInt32(connection_timeout);
        conn.StatementTimeout = Convert.ToInt32(statement_timeout);
        return new Server(conn);
    }



    //performing attache DB 
     static void AttachDb(string dbname, string filelist)
        {
            string[] files = filelist.Split(new char[] {'['}, StringSplitOptions.RemoveEmptyEntries);
            StringCollection dbfiles = new StringCollection();
            foreach (string s in files) {
                string s1 = s.TrimEnd(null);
                s1 = s1.TrimEnd(']');
                if (s1.Length > 0) dbfiles.Add(s1);
            }
            Server svr = Connect();
            string name = DecodeString(dbname);
            svr.AttachDatabase(name, dbfiles);
        }

通过向SQL Server 数据库实例的NT AUTHORITY\SYSTEM登录提供所有服务器角色来解决问题。
