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.

//create server connection object

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);
