具有复杂对象类型的JSon序列化问题已提交给MVC控制器

Question

当我们在jquery中调用.getJson时，我们想要一些关于为什么没有填充对象的List（下面）的指导。

我们在c＃中有以下内容。

public class NCListModel
{
   public NCListModel()
    {

    }
    public List<NCField> ActiveColumns { get; set; }
    public string IdColValue { get; set; }
    public string IdColText { get; set; }
    public int ID { get; set; }
    public string ListName { get; set; }
    public int PageNumber { get; set; }
    public int RecordsPerPage { get; set; }
    public int TotalRecords { get; set; }
    public int TotalPages { get; set; }
    public string SortBy { get; set; }
    public string SortDir { get; set; }
    public string SearchBy { get; set; }
    public string SearchTerm { get; set; }
    public byte ViewMode { get; set; }
}

 [Serializable]
    [ProgId("NCField_NET.NCField")]
    public class NCField
    {
        public NCField();

        public bool CanShow { get; set; }
        public string Caption { get; set; }
        public short Col { get; set; }
        public short ColLen { get; set; }
        public short DataType { get; set; }
        public short FieldLength { get; set; }
        public string FieldName { get; set; }
        public bool Hidden { get; set; }
        public string ImageName { get; set; }
        public bool IsDataField { get; }
        public bool IsDefaultFilter { get; set; }
        public bool IsFilter { get; set; }
        public bool IsID { get; set; }
        public bool IsLocation { get; set; }
        public bool IsSalesRep { get; set; }
        public bool IsSearchFilter { get; set; }
        public short LookupListID { get; set; }
        public string Name { get; set; }
        public string ValueSQL { get; set; }
    }

在jQuery中我们为反序列化赋值

var listinfo = {"ActiveColumns":[{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"FullName","DataType":1,"Col":0,"FieldLength":0,"Caption":"Name","FieldName":"Customer.FullName","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":true,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"CompanyName","DataType":1,"Col":2,"FieldLength":0,"Caption":"Company","FieldName":"Customer.CompanyName","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":false,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"BillAddr2","DataType":1,"Col":6,"FieldLength":0,"Caption":"Bill Addr2","FieldName":"Customer.BillAddr2","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":false,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"BillCity","DataType":1,"Col":7,"FieldLength":0,"Caption":"Bill City","FieldName":"Customer.BillCity","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":false,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"BillZip","DataType":1,"Col":8,"FieldLength":0,"Caption":"Bill Zip","FieldName":"Customer.BillZip","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":false,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"BillState","DataType":1,"Col":9,"FieldLength":0,"Caption":"Bill State","FieldName":"Customer.BillState","Hidden":false,"CanShow":true,"IsDataField":true,"IsFilter":true,"IsID":false,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":true,"LookupListID":0},{"IsSalesRep":false,"IsLocation":false,"ValueSQL":null,"Name":"NCCustomerID","DataType":3,"Col":99,"FieldLength":0,"Caption":"ID","FieldName":"Customer.NCCUstomerID","Hidden":false,"CanShow":false,"IsDataField":true,"IsFilter":false,"IsID":true,"IsDefaultFilter":false,"ColLen":0,"ImageName":"","IsSearchFilter":false,"LookupListID":0}],"IdColValue":"NCCustomerID","IdColText":"FullName","ID":120,"ListName":"Customer","HTML":null,"PageNumber":0,"RecordsPerPage":0,"TotalRecords":0,"TotalPages":0,"SortBy":"BillZip","SortDir":"asc","SearchBy":"FullName","SearchTerm":"","ViewMode":0}



we call this function in jquery.

function LoadData(st) {
    listinfo.SearchTerm = st;


    // need paging also.
    $.ajax({
        type: 'GET',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        url: uLink,
        data: listinfo,
        async: false,
        success: function (json) {

            if (json.Message === undefined)
            { $('#table-body').html(json.HTML); }
            else {
                alert(json.Message);
            }
        },
        error: function (jqXHR, textStatus, errorThrown) {
            alert(jqXHR.responseText);
        }
    });

}

我们看到listinfo是jQuery中的完整对象。

控制器接收具有适当数量的ActiveColumns的对象，但不会填充单个NCField对象的任何属性。

public JsonResult LoadData(NCListModel data)

{.....}
