Question

我是一名java开发人员，我第一次在.net上工作。我在YUI中使用了JSON，但这是我第一次使用JQUERY。我已经使用JSON.stringify()将Java脚本对象转换为JSON字符串，并且我在后面的代码中获得相同的JSON字符串，但是当我尝试反序列化为.net对象时，我获取的属性值为Integer，但我没有得到String对象的值。

//客户端

$("#ButtonSave").click(function () {

    //convert gridview to JSON
    var jsonData = new Array();
    $.map($("table[id*=Gridview1] tr"), function (item, index) {
        if ($(item).find("input[type=text]").length > 0) {
            jsonData[index] = new Object();
            jsonData[index].charge = $(item).find("input[type=text][id*=txtCharge]").val();
            jsonData[index].produce = $(item).find("input[type=text][id*=txtProduce]").val();         
            jsonData[index].weight = $(item).find("input[type=text][id*=txtWeight]").val();
            jsonData[index].feet = $(item).find("input[type=text][id*=txtFeet]").val();
            jsonData[index].orderNumber = $(item).find("input[type=text][id*=txtOrderNumber]").val(); 
            jsonData[index].comments = $(item).find("input[type=text][id*=txtComments]").val();
        }
    });

    var jsonStringData = JSON.stringify(jsonData);

    var jqxhr = $.ajax({
        url: "Correction.aspx",
        type: "POST",
        timeout: 10000,
        data: "jsonData=" + jsonStringData
    })
    .error(function () {
        alert('Error');
    })
    .success(function (data) {
        alert('Success');
    });
});

//代码背后

 If Request.Form("jsonData") IsNot Nothing Then

        Dim cita As New TurnDetailVO
        Dim ser As New JavaScriptSerializer()
        Dim items As List(Of TurnDetailVO) = ser.Deserialize(Of List(Of TurnDetailVO))(Request.Form("jsonData"))

        items.RemoveAt(0)

        For Each cita In items
            Console.WriteLine(cita.CHARGE_ID, cita.PROD_ID)
        Next

 End If

Answer 1

由于您的两个字段名称不同，看起来deserializtion的行为不符合预期。

如果我将属性名称PROD更改为PRODUCE而将ORDER_NUMBER更改为ORDERNUMBER，我可以将其设置为正常工作。请注意，您可以保留私有字段名称，它只是需要更改的属性名称。

JSON在vb.net代码中反序列化
