根据服务名称，获取sql server 里的数据库表名

public List<string> GetMSSQLDBNameList(string DSN, string UID, string PWD)
        {
           List<string> databases=new List<string> ();
            SqlConnection Connection = new SqlConnection(String.Format("Data Source={0};Initial Catalog=master;User ID={1};PWD={2}", DSN, UID, PWD));
            DataTable DBNameTable = new DataTable();

//从系统表master..sysdatabases中查询数据库名字
            SqlDataAdapter Adapter = new SqlDataAdapter("select name from master..sysdatabases", Connection);
            Adapter.Fill(DBNameTable);

            foreach (DataRow Row in DBNameTable.Rows)
            {
                databases.Add(Row[0].ToString());
            }

            return databases;
        }
         public List<string> GetMSSQLDBNameList(string DSN)
         {
             List<string> databases = new List<string>();
             SqlConnection Connection = new SqlConnection(String.Format("Data Source={0};Initial Catalog=master;Integrated Security=True", DSN));
             DataTable DBNameTable = new DataTable();
             SqlDataAdapter Adapter = new SqlDataAdapter("select name from master..sysdatabases", Connection);
             Adapter.Fill(DBNameTable);

             foreach (DataRow Row in DBNameTable.Rows)
             {
                 databases.Add(Row[0].ToString());
             }

             return databases;
         }
