ASP.NET实现弹出框真分页将复选框选择的数据存到数据库中（四）

这是第四步点击保存将信息存入数据库中。

这个就简单了利用ajax将JSON字符串传到后台然后这里有个知识点就是将DataTable直接存入数据库中。代码如下：

一、界面获取数据JS代码：

//保存订单信息
function SaveToJson() {
    //单位
    var Company = document.getElementById("lblCompany").innerHTML;
    //NO
    var OrderNo = document.getElementById("lblNO").innerHTML;
    //下单类型
    var XDLX = document.getElementById("ddXDLX").value;
    //转库凭证号
    var ZKPZH = document.getElementById("txtZKPZH").value;
    //日期
    var OrderDate = document.getElementById("lblDate").innerHTML;
    //代理商ID
    var intDLSID = document.getElementById("hidDLSID").value;
    strReturned = returned.toString()

    $.post("../DDGL/handler/SaveZCXDInfo.ashx", { strReturned: strReturned, Company: Company, OrderNo: OrderNo, XDLX: XDLX, ZKPZH: ZKPZH, OrderDate: OrderDate, intDLSID: intDLSID }, function(data) {
        if (data == "True") {
            alert("添加成功！")
        } else {
            alert("添加失败！")
        }
        window.location.href = "QueryDJLJList.aspx";
    });

}

二、SaveZCXDInfo.ashx代码。

这个代码中我将JSON字符串转化成对象，在将对象转化成和数据库表结构一致的DataTable。代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json;
using Model;
using BLL;
using System.Data;

namespace WEB.DDGL.handler
{

    public class QueryTotalMoney : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            //获取主表信息
            int intDLSID = Convert.ToInt32(context.Request.Form["intDLSID"].ToString().Trim());
            string strLJInfo = context.Request.Form["strReturned"].ToString();
            string strCompany = context.Request.Form["Company"].ToString();
            string strOrderNo = context.Request.Form["OrderNo"].ToString();
            string strXDLX = context.Request.Form["XDLX"].ToString();
            string strZKPZH = context.Request.Form["ZKPZH"].ToString();
            string strOrderDate = context.Request.Form["OrderDate"].ToString();
            //主表插入信息
            MT_DLS_Order Order = new MT_DLS_Order();
            Order.beginDate = strOrderDate;
            Order.Company = strCompany;
            Order.DLSID = intDLSID.ToString();
            Order.XDLX = strXDLX;
            Order.ZKPZH = strZKPZH;
            Order.OrderCode = strOrderNo;
            Order.SFQBFH = "否";
            Order.IsCancel = "否";
            Order.SFJRFee = "否";
            //获取从表信息
            /*
             *  1、新建一个DataTable
             *  2、把传来的Json字符串改成数组
             *  3、把数组变成对象
             *  4、把对象的值赋给DataTable
             * */
            //新建一个DataTable
            DataTable dtLJInfo = new DataTable("T_DLS_Order_Cong");
            dtLJInfo.TableName = "T_DLS_Order_Cong";
            //添加DataTable数据项
            dtLJInfo.Columns.Add(new DataColumn("ID", typeof(int)));
            dtLJInfo.Columns.Add(new DataColumn("name", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("beginDate", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("OrderID", typeof(int)));
            dtLJInfo.Columns.Add(new DataColumn("LJID", typeof(int)));
            dtLJInfo.Columns.Add(new DataColumn("LJBM", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("LJMC", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("Numbers", typeof(int)));
            dtLJInfo.Columns.Add(new DataColumn("Money", typeof(decimal)));

            dtLJInfo.Columns.Add(new DataColumn("FHRName", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("FHDate", typeof(string)));
            dtLJInfo.Columns.Add(new DataColumn("IsCancel", typeof(string)));
            //把Json字符串改成数组
            JArray jaLJInfo = (JArray)JsonConvert.DeserializeObject(strLJInfo);
            if (strXDLX == "正常下单")
            {
                for (int i = 0; i < jaLJInfo.Count; i++)
                {
                    JObject obj = (JObject)jaLJInfo[i];
                    DataRow drLJInfo = dtLJInfo.NewRow();
                    string strLJID = obj["LJID"].ToString().Trim();
                    string strNumbers = obj["SL"].ToString();
                    string strMoney = obj["Money"].ToString();

                    strLJMC = strLJMC.Replace("\"", "");
                    drLJInfo["LJID"] = Convert.ToInt32(strLJID);
                    drLJInfo["LJBM"] = strLJBM;
                    drLJInfo["LJMC"] = strLJMC;
                    drLJInfo["Numbers"] = Convert.ToInt32(strNumbers);
                    drLJInfo["Money"] = Convert.ToDecimal(strMoney);
                    drLJInfo["beginDate"] = strOrderDate;
                    drLJInfo["IsCancel"] = "否";
                    drLJInfo["SFFH"] = "否";
                    dtLJInfo.Rows.Add(drLJInfo);
                }
            }
            else
            {
                for (int i = 0; i < jaLJInfo.Count; i++)
                {
                    JObject obj = (JObject)jaLJInfo[i];
                    DataRow drLJInfo = dtLJInfo.NewRow();
                    string strLJID = obj["LJID"].ToString().Trim();
                    string strMoney = obj["Money"].ToString();
                    string strLJBM = obj["LJBM"].ToString();
                    string strLJMC = obj["LJMC"].ToString();
                    string strDJNo = obj["DJBH"].ToString();

                    strLJID = strLJID.Replace("\"", "");
                    strMoney = strMoney.Replace("\"", "");
                    strLJBM = strLJBM.Replace("\"", "");
                    strLJMC = strLJMC.Replace("\"", "");
                    strDJNo = strDJNo.Replace("\"", "");
                    drLJInfo["LJID"] = Convert.ToInt32(strLJID);
                    drLJInfo["LJBM"] = strLJBM;
                    drLJInfo["LJMC"] = strLJMC;
                    drLJInfo["Money"] = Convert.ToDecimal(strMoney);
                    drLJInfo["beginDate"] = strOrderDate;
                    drLJInfo["DJNo"] = strDJNo;
                    drLJInfo["SFFH"] = "否";
                    drLJInfo["IsCancel"] = "否";

            BT_XDMgr XDMgr = new BT_XDMgr();
            if (XDMgr.AddOrder(Order, dtLJInfo))
            {
                context.Response.Write("True");

            }
            else
            {
                context.Response.Write("False");
            }

            context.Response.End();
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

三、BLL层代码。

    /// <summary>
    /// 添加到数据库
    /// </summary>
    /// <param name="Order"></param>
    /// <param name="dt"></param>
    /// <returns></returns>
        public bool AddOrder(MT_DLS_Order Order,DataTable dt)
        {

            DT_DLS_Order OrderDal = new DT_DLS_Order();
            DT_DLS_Order_Cong OrderCongDal = new DT_DLS_Order_Cong();
            DT_DLS_Order_LC OrderLCDal = new DT_DLS_Order_LC();
            decimal TotalMoney=0;
            //添加主单信息
            int OrderID = OrderDal.Add(Order);
            //添加订单ID在从表中
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                dt.Rows[i]["OrderID"] = OrderID;
                TotalMoney = TotalMoney +Convert.ToDecimal( dt.Rows[i]["Money"].ToString().Trim());
            }
            //更新总金额
            Order.ID = OrderID;
            Order.OrderMoney = TotalMoney;
            //判断是否更新成功
            if (OrderDal.Update(Order))
            {
                //添加订单从表
                //判断是否添加从表成功
                if (OrderCongDal.AddOrderInfoByDataTable(dt))
                {
                    //添加此订单的流程
                    //查询出流程ID
                    //查询所有的节点ID
                    int ZFGDLS = Convert.ToInt32(ConfigurationSettings.AppSettings["ZFGDLS"].ToString());
                    DataTable dtZFGDLSJD = new DataTable();
                    dtZFGDLSJD = OrderLCDal.QueryAllJD(ZFGDLS);
                    //判断流程中是否有节点
                    if (dtZFGDLSJD.Rows.Count > 0)
                    {
                        DataTable dtOrderLC = new DataTable();
                        dtOrderLC.TableName = "T_DLS_Order_LC";
                        dtOrderLC.Columns.Add(new DataColumn("ID", typeof(int)));
                        dtOrderLC.Columns.Add(new DataColumn("name", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("beginDate", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("OrderID", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("LCID", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("State", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("CZRNo", typeof(string)));
                        dtOrderLC.Columns.Add(new DataColumn("CZRName", typeof(string)));

                        for (int i = 0; i < dtZFGDLSJD.Rows.Count; i++)
                        {
                            DataRow drOrderLCInfo = dtOrderLC.NewRow();

                            drOrderLCInfo["OrderID"] = Order.ID;
                            drOrderLCInfo["LCID"] = dtZFGDLSJD.Rows[i]["ID"].ToString().Trim();

                            if (i == 0)
                            {
                                drOrderLCInfo["State"] = "是";
                                drOrderLCInfo["CZRNo"] = Order.DLSID;
                                drOrderLCInfo["CZRName"] = Order.Company;
                                drOrderLCInfo["beginDate"] = Order.beginDate;
                            }
                            else
                            {
                                drOrderLCInfo["State"] = "否";
                            }
                            dtOrderLC.Rows.Add(drOrderLCInfo);
                        }
                       //判断添加流程是否成功
                        if (OrderLCDal.AddOrderLC(dtOrderLC))
                        {
                            return true;
                        }
                        else
                        {
                            return false;
                        }

                    }
                    else
                    {
                        return false;
                    }

                }
                else
                {
                    return false;
                }

            }
            else
            {
                return false;
            }

        }

四、D层中关键的代码。

将传回去的DataTable直接存到数据库中：

代码如下：

/// <summary>
    /// 将datatable中的数据批量插入数据库
    /// </summary>
    /// <param name="dt"></param>
    /// <returns></returns>
    public static Boolean makeDatatableIntoDatabase(DataTable dt)
    {
        SqlBulkCopy sqlbulkcopy = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.UseInternalTransaction);
        sqlbulkcopy.DestinationTableName = dt.TableName;//数据库中的表名

        try
        {
            sqlbulkcopy.WriteToServer(dt);
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }

       这里值得注意的是：我们传过来的DataTable TableName要和数据库中表名一致，DataTable中的字段顺序，类型、名称要和数据库中的字段字段顺序，类型、名称一致才行。

五、效果图。

六、综述。

就这四步把整个功能一一展现出来了用到的知识点很多。从这个功能中我的体会就是实习完回去赶紧多做些这样的小Demo保存好工作的时候直接用不要等到工作了慢慢的研究。其实我们做项目都是一个个小Demo拼接出来的。所以多做Demo工作上遇到了开发效率就高了。
