c# - 如何在 asp.net mvc Controller 中获取发布的表单数据

Question

我已经使用 View 中的 $.ajax 方法发布了数据。我没有在 Controller 中获取发布的数据我尝试过以不同的方式获取数据但没有成功。这是我发布的代码

       $.ajax({
            url: "/Groupage/UpdateAddresses",
            type: "POST",
            contentType: "JSON/Application",
            data: JSON.stringify(sr)
        });


[HttpPost]
public void UpdateAddresses(IEnumerable<GroupageAddress> addresses,FormCollection coll)
 {
       //saving data in db
        var list = Request.QueryString.Cast<GroupageAddress>();
        var list1 = Request.QueryString.Cast<IEnumerable<GroupageAddress>>();
      //getting null for addresses parameter
     //Used request

 } 

这里是分组地址类属性

   public class GroupageAddress
    {
    [Key]
    public int Id { get; set; }
    [Required]
    [Display(Name = "Transport Job Id")]
    public int GroupageJobId { get; set; }
    public int TransportJobId { get; set; }
    //Company name is not required
    [Display(Name = "Company Name")]
    public string CompanyName { get; set; }
    [Required]
    [Display(Name = "Address1")]
    public string Address1 { get; set; }

    [Display(Name = "Address2")]
    public string Address2 { get; set; }
    [Required]
    [Display(Name = "City")]
    public string City { get; set; }
    [Required]
    [Display(Name = "County")]
    public string County { get; set; }
    [Required]

    [Display(Name = "Post Code")]
    public string PostCode { get; set; }
    [Required]
    [Display(Name = "Country")]
    public int CountryId { get; set; }

    [Required]
    [Display(Name = "Global Transport Job Address Type Id")]
    public int GlobalTransportJobAddressTypeId { get; set; }
    [Display(Name = "Date")]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Date { get; set; }
    [Display(Name = "Time From")]

    public DateTime? TimeFrom { get; set; }
    [Display(Name = "Time To")]

    public DateTime? TimeTo { get; set; }
    [Display(Name = "Actual Time")]

    public DateTime? ActualTime { get; set; }

    public int GroupageAddressSequenceId { get; set; }

    [Display(Name = "Is Active")]
    public bool IsActive { get; set; }
    [ScriptIgnore(ApplyToOverrides = true)]
    public virtual GroupageJob GroupageJob { get; set; }
   }

这里是发布的表单数据

我观察到基于内容类型mvc会响应数据。我只使用了 $.post("/Groupage/UpdateAddresses",JSON.stringify(sr)) 但它发送的内容类型为 application/x-www-form-urlencoded;字符集=UTF-8当我像下面这样使用 with 时内容类型更改为“Application\JSON”

  $.ajax({
        url: "/Groupage/UpdateAddresses",
        type: "POST",
        contentType: "Application/JSON",
        data: JSON.stringify(sr)
    });

以C#对象的形式反序列化数据作为方法中的参数。
