MSSQL使用sqlbulkcopy批量插入数据

具体代码如下：

 /// <summary>
         /// 批量插入数据到BayonetZipFailedPic表
         /// </summary>
         /// <param name="bayonetFailedPicList">含有多条拷贝失败的二次卡口图片数据的集合</param>
         /// <returns>0-成功，-2-异常，其他-失败</returns>

         {

             try
             {
                 DataTable dataTable = GetBayonetZipFailedPicTableSchema();
                 foreach (BayonetZipFailedPic bayonetFailedPic in bayonetFailedPicList)
                 {

                 }
