一般處理程序頁ashx 序列化 Json數組

json傳遞數組到一般處理程序頁，序列化為實體類的方法，可以解決.ENT framework 3.5以前的項目，

3.5以后的項目可以用System.ServiceModel.Web和System.Runtime.Serialization解決，當然也可以使用這種方案。

 

下面是代碼：

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("溫馨提示", "生成預訂單，確定繼續嗎？溫馨提示", 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", "生成采購計划成功！");
                            $("#dataTb tbody tr input[type='checkbox']").attr("checked",false);
                            $("#dataTb tbody tr input[name='purchase_num']").val("0");
                        } else {
                            $.MsgBox.Alert("提示", "生成采購計划失敗！");
                            return false;
                        }
                    }
                });

            });
        } else {
            $.MsgBox.Alert("提示", "請選擇要處理的記錄！");
            return false;
        }

    }

ASHX 畫面：

引用：using Newtonsoft.Json;

接收數組字符串：

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

序列化為實體類

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

實體類：

/// <summary>
    /// ET_PURCHASE_ITEM:實體類(屬性說明自動提取數據庫字段的描述信息)
    /// </summary>

    public partial class ET_PURCHASE_ITEM
