C# Web Api服务器端处理和数据表参数

我试图创建一个对象，该对象表示datatables提供给我的web api调用的值，然后将其路由到另一个实际返回值的api（以将datatables与api接口分离）

在研究了datatables wiki之后，我最终定义了以下对象：

public class DataTableParameters
{
    public int draw { get; set; }
    public int start { get; set; }
    public int length { get; set; }
    public order[] order { get; set; }
    public column[] columns { get; set; }
}

public class order
{
    public int column { get; set; }
    public string dir { get; set; }
}

public class column
{
    public string data { get; set; }
    public string name { get; set; }
    public bool searchable { get; set; }
    public bool orderable { get; set; }
    public search search { get; set; }
}

public class search
{
    public string value { get; set; }
    public bool regex { get; set; }
}

但是，当我尝试将它们用作DataTables api控制器的参数时，结果为空：

    public DataTableResult Get(DataTableParameters parameters) //parameters is null!
    {
         return new DataTableResult();
    }

据我所知，模型绑定应该是读取结果并将其应用于我的对象。这是一个从前端调用api的示例：

Key Value
Request GET /MVC/api/DataTables?action=Get&draw=1&columns%5B0%5D%5Bdata%5D=0&columns%5B0%5D%5Bname%5D=&columns%5B0%5D%5Bsearchable%5D=true&columns%5B0%5D%5Borderable%5D=true&columns%5B0%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B0%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B1%5D%5Bdata%5D=1&columns%5B1%5D%5Bname%5D=&columns%5B1%5D%5Bsearchable%5D=true&columns%5B1%5D%5Borderable%5D=true&columns%5B1%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B1%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B2%5D%5Bdata%5D=2&columns%5B2%5D%5Bname%5D=&columns%5B2%5D%5Bsearchable%5D=true&columns%5B2%5D%5Borderable%5D=true&columns%5B2%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B2%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B3%5D%5Bdata%5D=3&columns%5B3%5D%5Bname%5D=&columns%5B3%5D%5Bsearchable%5D=true&columns%5B3%5D%5Borderable%5D=true&columns%5B3%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B3%5D%5Bsearch%5D%5Bregex%5D=false&order%5B0%5D%5Bcolumn%5D=0&order%5B0%5D%5Bdir%5D=asc&start=0&length=10&search%5Bvalue%5D=&search%5Bregex%5D=false&_=1440437669357 HTTP/1.1

为什么我的parameters对象为空，如何修复它

编辑：我还尝试了以下操作：

 public DataTableResult Get(int draw, int start, int length, column[] columns, order[] order)
    {
        return new DataTableResult();
    }

---

但是我得到“无法将多个参数（'columns'和'order'）绑定到请求的内容。”

不到10分钟后，我需要参数上的[FromUri]属性

 public DataTableResult Get([FromUri]DataTableParameters parameters)
 {
      return new DataTableResult();
 }
