爲PetaPoco添加Fill方法

因爲公司框架中的很多地方用到DataTable，直接將DataTable作爲數據源綁定到DataGridView，所以爲PetaPoco添加了兩個方法，一個是用以填充單個DataTable，一個是用以多結果集時填充DataSet。

 

#region operation Fill

        /// <summary>
        /// 填充一個DataSet
        /// </summary>
        /// <param name="ds">引用的DataSet</param>
        /// <param name="sql">sql語句</param>
        /// <param name="args">參數</param>
        public void Fill(DataSet ds, string sql, params object[] args)
        {
            OpenSharedConnection();

            try
            {
                using (var cmd = CreateCommand(_sharedConnection, sql, args))
                {
                    using (DbDataAdapter dbDataAdapter = _factory.CreateDataAdapter())
                    {
                        dbDataAdapter.SelectCommand = (DbCommand)cmd;
                        dbDataAdapter.Fill(ds);
                    }
                }
            }
            finally
            {
                CloseSharedConnection();
            }
        }

        /// <summary>
        /// 填充一個DataTable
        /// </summary>
        /// <param name="dt">DataTable的引用</param>
        /// <param name="sql">Sql語句</param>
        /// <param name="args">參數</param>
        public void Fill(DataTable dt, string sql, params object[] args)
        {
            OpenSharedConnection();

            try
            {
                using (var cmd = CreateCommand(_sharedConnection, sql, args))
                {
                    using (DbDataAdapter dbDataAdapter = _factory.CreateDataAdapter())
                    {
                        dbDataAdapter.SelectCommand = (DbCommand)cmd;
                        dbDataAdapter.Fill(dt);
                    }
                }
            }
            finally
            {
                CloseSharedConnection();
            }
        }
