使用SqlBulkCopy插入DataTable到數據庫

 插入DataTable到數據庫代碼示例：

        /// <summary>
        /// 保存DataTable到數據庫
         /// </summary>
        /// <param name="dt">DataTable</param>
        public static void SaveDt(DataTable dt)
        {
            if (dt.Rows.Count > 0)
            {
                using (SqlConnection destinationConnection = new SqlConnection(PUB_Data.GetConfigStr("connectionString")))
                {
                    destinationConnection.Open();//打開連接
                       SqlTransaction bulkTran = destinationConnection.BeginTransaction();
                    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(destinationConnection, SqlBulkCopyOptions.CheckConstraints, bulkTran))
                    {
                        bulkCopy.DestinationTableName = "TableName";//目標數據表名
                        bulkCopy.BulkCopyTimeout = 30;
                        try
                        {
                            SqlCommand delComm = new SqlCommand("Delete From TabelName Where code = '" + dt.Rows[0][0].ToString() + "'", destinationConnection, bulkTran);
                            delComm.ExecuteNonQuery();
                            bulkCopy.WriteToServer(dt);
                            bulkTran.Commit();
                        }
                        catch (Exception eBulk)
                        {
                            bulkTran.Rollback();
                            throw eBulk;
                        }
                        finally
                        { bulkCopy.Close(); }
                    }
                    destinationConnection.Close();
                }
            }
        }
