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 == 0)
            {
                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;
        }
