将AJAX Post的Data转为对应的Class

　　在使用DataTables从服务端获取数据时，在非MVC的情况下没有MVC的自动绑定功能，所以需要自己写一个绑定，将Post过来的InputStream转为对应的类。

　　HTML:

　　

<form id="formSearch" runat="server" class="form-horizontal">

        <div class="container-fluid">

            <div class="form-group">

                <asp:Label CssClass="col-sm-2 control-label" runat="server" Text="<%$ Resources:Resource,Form_Id1 %>"></asp:Label>

                <div class="col-sm-4">

                    <input type="text" class="form-control" id="formID" name="formID" maxlength="64" />

                </div>

                <asp:Label CssClass="col-sm-2 control-label" runat="server" Text="<%$ Resources:Resource,Process_Name1 %>"></asp:Label>

                <div class="col-sm-4">

                    <select class="form-control" id="FlowID" name="FlowID">

                    </select>

                </div>

            </div>

            <div class="form-group">

                <asp:Label runat="server" CssClass="col-sm-2 control-label" Text="<%$ Resources:Resource,Apply_Person1 %>"></asp:Label>

                <div class="col-sm-4">

                    <input type="text" id="applyPerson" name="applyPerson" class="form-control" maxlength="64" />

                </div>

                <div class="col-sm-2">

                    <button id="btnSearch" class="btn btn-primary">

                        <asp:Literal runat="server" Text="<%$ Resources:Resource,Search %>"></asp:Literal>

                    </button>

                </div>

            </div>

        </div>

    </form>

　　JS:

function BindList() {

        if (table == null) {

            table = $list.DataTable({

                ajax:

                {

                    url: "/PageHandle/TaskHandler.ashx?type=MyTask",

                    contentType: "application/json; charset=utf-8",

                    dataType: "json",

                    data: function (d) {

                        return JSON.stringify($.extend({}, d, $.getJsonFromForm($("#formSearch"))));

                    }

                },

                columns: [

                    {

                       XXXXXXXXX

                ],

            });

        }

    }

　　TaskRQ：

　　

public class TaskRQ : BaseDataTablesRequest

    {

        //public bool isTempNameZh_cn { get; set; }

        public string currentUser { get; set; }

        public string urgentCase { get; set; }

        public string FlowID { get; set; }

        public string taskStatus { get; set; }

        public string formID { get; set; }

        public string activityName { get; set; }

        public string applyPerson { get; set; }

        public bool isChina { get; set; }

        public DateTime? applyDateFrom { get; set; }

        public DateTime? applyDateTo { get; set; }

        //public DateTime? assignDateFrom

        //{

        //    get; set;

        //}

        //public DateTime? assignDateTo { get; set; }

        //public string orderBy { get; set; }

    }

　　注意：被转换的对象的字段名必须与Html中的Name字段一致，否则将忽略该对象的赋值。

使用JavaScriptSerializer来将InputStream转为TaskRQ对象。

public void ProcessRequest(HttpContext context)

        {

            var rq = GetTaskRQ(context);

            var taskS = new WFTaskS();

            object rp ;

            var type = context.Request["type"];

            switch (type)

            {

                case "MyTask":

                    rp = taskS.GetMyTask(rq);

                    break;

                case "MyChildTask":

                    rp = taskS.GetMyChildTask(rq);

                    break;

                case "MyDelegatedTask":

                    rp = taskS.GetDelegatedTask(rq);

                    break;

                case "AllTask":

                    rp = taskS.GetAllTask(rq);

                    break;

                default:

                    rp = taskS.GetMyTask(rq);

                    break;

            }

            var js = new JavaScriptSerializer();

            var result = js.Serialize(rp);

            context.Response.ContentType = "application/json; charset=utf-8";

            context.Response.Write(result);

        }

        public bool IsReusable

        {

            get

            {

                return false;

            }

        }

        /// <summary>

        /// 获得Post来的InputStream，将其转化为Json，并将Json反序列化为对象

        /// </summary>

        /// <param name="context"></param>

        /// <returns></returns>

        private TaskRQ GetTaskRQ(HttpContext context)

        {

            var stream = context.Request.InputStream;

            if (stream.Length == )

            {

                return null;

            }

            var reader = new StreamReader(stream);

            var json = reader.ReadToEnd();

            var js = new JavaScriptSerializer();

            var rq = js.Deserialize<TaskRQ>(json);

            var IsChina = false;

            if (HttpContext.Current.Session != null

                && HttpContext.Current.Session["_Localization"] != null

                && HttpContext.Current.Session["_Localization"].ToString().ToLower() == "zh-cn")

            {

                IsChina = true;

            }

            rq.isChina = IsChina;

            return rq;

        }
