对于C#Execl数据的导入导出大家不感到陌生，这是一个项目中经常回遇到的功能，今天在这里讲的事，使用SqlBulkCopy类实现导入Excel大批量的数据导入。

/// <summary>  
/// 数据库对应表  
/// </summary>  
/// <returns></returns>  
        private static DataTable GetDeliveryOrderTable()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("ShipperID", typeof(string));
            dt.Columns.Add("ConsigneeProvince", typeof(string));
            dt.Columns.Add("ConsigneeName", typeof(string));
            dt.Columns.Add("ConsigneeContact", typeof(string));
            dt.Columns.Add("ConsigneeAddress", typeof(string));
            dt.Columns.Add("ConsigneeMobile", typeof(string));
            dt.Columns.Add("ShipperName", typeof(string));
            dt.Columns.Add("TransportDate", typeof(DateTime));
            dt.Columns.Add("PlanEndDate", typeof(DateTime));
            dt.Columns.Add("EndDate", typeof(DateTime));
            dt.Columns.Add("Status", typeof(string));
            dt.Columns.Add("CheckStatus", typeof(string));
            dt.Columns.Add("OrderSource", typeof(string));
            dt.Columns.Add("Creator", typeof(string));
            dt.Columns.Add("Creator_ID", typeof(string));
            dt.Columns.Add("CreateTime", typeof(DateTime));
            return dt;
        }
