如何将 JSON 数组发送到 ASP.NET MVC 控制器

Question

我正在尝试将 JSON 数组发送到 ASP MVC 控制器。我首先尝试了一个 JSON 对象，它确实有效，但在我尝试数组 JSON 对象时失败了。正如下面的代码所示，我希望得到 ListForm2 是，

ListForm2[0].MarketID = 1, ......

ListForm2[1].MarketID = 2, ......

但是，我得到了 ListForm2=null。我的编码有什么问题？

function ProcessSaveView(area, bChecked, bChart, saveName) {
    var jsondata = [{ MarketID: 1, ForecastPointTypeID: 5, ForecastPointID: 21, CustomTimeZoneID: "ET-Prevailing", IsChart: true },
                    { MarketID: 2, ForecastPointTypeID: 5, ForecastPointID: 51, CustomTimeZoneID: "ET-Prevailing", IsChart: true }];

    $.ajax({
        type: "POST",
        url: "./charts/SaveViewToDatabase",
        dataType: "json",
        traditional: true,
        data: jsondata,
        success: function (result) {
            if (result.success) {
                alert("Save View successful!");
            } else {
                alert("Duplicate View already exist. Not save!");
            }
        },
        error: function () {
            alert("No market, load type & region is selected!");
        }
    });
}

[HttpPost]
public ActionResult SaveViewToDatabase(testJsonObject[] ListForm2)
{
    return Json(new { success = true });
}

public class testJsonObject
{
    public int ForecastPointID { get; set; }
    public int MarketID { get; set; }
    public int ForecastPointTypeID { get; set; }
    public string CustomTimeZoneID { get; set; }
    public bool IsChart { get; set; }
}

尝试以下操作：

$.ajax({
    type: "POST",
    url: "./charts/SaveViewToDatabase",
    dataType: "json",
    contentType: "application/json",
    data: JSON.stringify(jsondata),
    success: function (result) {
        if (result.success) {
            alert("Save View successful!");
        } else {
            alert("Duplicate View already exist. Not save!");
        }
    },
    error: function () {
        alert("No market, load type & region is selected!");
    }
});
