我有一个困难的时间张贴从我的视图到控制器的数组列表。所有其他的价值都在传递。
有人能发现我的代码有什么问题吗？
控制器：

public ActionResult SaveProgress(BBCRMSurveyVM model)
{
    try
    {
        return Json(new { success = true });
    }
    catch (Exception e)
    {
        return Json(new { success = false, msg = e.Message });
    }
}

主视图模型：

public string ImplementationProcessFeelWasSuccessful { get; set; }
public string ImplementationProcessAdviceOtherFederations { get; set; }
public List<AdditionalTechnologyVM> AdditionalTech = new List<AdditionalTechnologyVM>();

其他TechVM：

public class AdditionalTechnologyVM
{
    public string PlatformName { get; set; }
    public string BusinessPurpose { get; set; }
    public bool? FullyIntegrated { get; set; }
    public bool? PartiallyIntegrated { get; set; }
}

JS文件：

function onAddButtonClickEvent() {
    additionaltechs.push({
       'PlatformName': platformNameAT,
       'BusinessPurpose': businessPurposeAT,
       'FullyIntegrated': integrated == "Fully" ? true : false,
       'PartiallyIntegrated': integrated == "Partially" ? true : false
    });
}

function SaveProgress() {
    var formData = $('#wizard').serializeArray();

    //if (additionaltechs.length > 0) {
    //    for (var x = 0; x < additionaltechs.length; x++) {
    //        formData[formData.length] = { name: "AdditionalTech", value: JSON.stringify(additionaltechs[x]) };
    //    }
    //}

    formData[formData.length] = { name: "AdditionalTech", value: additionaltechs };

    $.each(formData, function (index, field) {
        if (field.name.search('Budget') > 0) {
            field.value = field.value.replace('$', '').replace(/,/g, '');
        }
    });

    formData = JSON.stringify(formData);

    console.log(formData);
    
    $.ajax({
        url: '/save-progress',
        contentType: 'application/json; charset=utf-8',
        type: 'POST',
        data: formData,
        dataType: 'json',
        success: function () {},
        error: function () {}
    });
}

控制台中的输出：

列表计数始终为0？
