C# 在同一控制器Asp.net Mvc中执行Post操作时，参数丢失值

我只想在控制器名称Home中的Mvc操作结果上发布同一控制器中的操作结果，post请求发送成功，但参数丢失传递值

从主控台呼叫Post

   [ValidateInput(false)]
    [HttpPost]
    public ActionResult addToWishList(string customcode, string addcusimgSVG, string pagestatus = "", string userinformation="")
    {

        string URI = "http://localhost:49389/services";
        string myParameters = "serviceAndVisitorModel=" + ServiceAndVisitroData;

        using (WebClient wc = new WebClient())
        {
            wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
            string HtmlResult = wc.UploadString(URI, myParameters);
        }
     //return some view here

    }

同一控制器中存在addToWishList调用的操作结果

  [Route("services")]
    [HttpPost]
    public ActionResult services(AllserviceWebApi serviceAndVisitorModel, string pagename = "service")//string selectedService,string userId,string DealInfo
    {

     //serviceAndVisitorModel is null here

    }

型号

public class AllserviceWebApi
{
    public string packageTypeID { get; set; }
    public string packageTypeCode { get; set; }
    public string pageUrl { get; set; }
    public string pageName { get; set; }
    public string displayName { get; set; }
    public string name { get; set; }
    public List<pakageInfoList> packageInfoList { get; set; }
    //------visitor object
    public string IPAddress { get; set; }
    public string deviceName { get; set; }
    public string OSName { get; set; }
    public string browserName { get; set; }
    public string countryName { get; set; }

    public string selectedService{ get; set; }
    public string userId{ get; set; }
    public string OrderId { get; set; }
    public string DealInfo { get; set; }
    public long wishlishid { get; set; }
    public string customlogoCode { get; set; }
    public string customLogoImgSvg { get; set; }
    public bool IsCustomllogo { get; set; }
}

请告诉我这段代码有什么问题。

尝试通过JSON发送

using Newtonsoft.Json;


    using (WebClient wc = new WebClient())
            {
                wc.Headers[HttpRequestHeader.ContentType] = "application/json";
                string HtmlResult = wc.UploadString(URI, JsonConvert.SerializeObject(ServiceAndVisitroData));
            }

PS您需要通过nuget安装Newtonsoft.Json

您是否尝试过该型号？？？什么是

服务和VisitroData

？（AllserviceWebApi serviceAndVisitorModel的

参数建议您要绑定到复杂对象-您不能将
字符串
绑定到复杂对象）@StephenMuecke请建议我如何绑定？我猜不出
AllserviceWebApi
是什么，或者
ServiceAndVisitroData的值是什么is@StephenMuecke请考虑我现在编辑的问题。
using Newtonsoft.Json;


    using (WebClient wc = new WebClient())
            {
                wc.Headers[HttpRequestHeader.ContentType] = "application/json";
                string HtmlResult = wc.UploadString(URI, JsonConvert.SerializeObject(ServiceAndVisitroData));
            }
