一般处理程序页ashx 序列化 Json数组

json传递数组到一般处理程序页，序列化为实体类的方法，可以解决.ENT framework 3.5以前的项目，

3.5以后的项目可以用System.ServiceModel.Web和System.Runtime.Serialization解决，当然也可以使用这种方案。

 

下面是代码：

JS

function PurchaseAutonomy() {

        var r = 0;

        var parmArr = new Array();

        $("#dataTb tbody tr").each(function () {

            var ch = $(this).children().eq(0).children().eq(0).attr("checked");

            var num = $(this).children().eq(7).children().eq(0).val();            

            if (ch == true)

            {

                if (IsNum(num)) {

                    return false;

                } else {

                    parmArr[r] = {

                        PRODUCT_ID: $(this).children().eq(1).text(),

                        PRODUCT_NAME: $(this).children().eq(3).text(),

                        ORG_ID: $(this).children().eq(0).children().eq(2).val(),

                        JS_PRICE: $(this).children().eq(0).children().eq(4).val(),

                        NOS_PRICE: $(this).children().eq(0).children().eq(3).val(),

                        PRODUCT_PRICE: $(this).children().eq(0).children().eq(4).val(),

                        PURCHASE_NUM: $(this).children().eq(7).children().eq(0).val()

                    };



                    r++;

                }

            }

        });

        

        if (r > 0) {



            $.MsgBox.Confirm("温馨提示", "生成预订单，确定继续吗？温馨提示", function () {

                var a = parmArr;

                $.ajax({

                    type: "POST",

                    url: "/DataServer/Purchase/PurchaseAdd.ashx",

                    data: { parmArr: JSON.stringify(parmArr),user_id:<%=user_id%>,bm_id:<%=bm_id%> },

                    datatype:"json",

                    contentType: "application/x-www-form-urlencoded; charset=utf-8",

                    success: function (result) {

                        if (result == "1") {

                            $.MsgBox.Alert("提示", "生成采购计划成功！");

                            $("#dataTb tbody tr input[type='checkbox']").attr("checked",false);

                            $("#dataTb tbody tr input[name='purchase_num']").val("0");

                        } else {

                            $.MsgBox.Alert("提示", "生成采购计划失败！");

                            return false;

                        }

                    }

                });



            });

        } else {

            $.MsgBox.Alert("提示", "请选择要处理的记录！");

            return false;

        }

ASHX 画面：

引用：using Newtonsoft.Json;

接收数组字符串：

String parmArr = context.Request.Form["parmArr"];

序列化为实体类

List<ET_PURCHASE_ITEM> list = new List<ET_PURCHASE_ITEM>();
list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<ET_PURCHASE_ITEM>>(parmArr);

实体类：

/// <summary>

    /// ET_PURCHASE_ITEM:实体类(属性说明自动提取数据库字段的描述信息)

    /// </summary>
