将JSON Body放到Web API中

Question

我试图发送这个JSON对象

{"from":{"Lat":30.075027703750937,"Lng":31.342577639657264,"Type":0},
"to":{"Lat":30.021339759652712,"Lng":31.284893204137528,"Type":0}}

到此Web API 2方法

[HttpPut]
public IHttpActionResult PutTicketDestination(Guid Id, [FromBody] Location from, [FromBody] Location to)

位置对象

public class Location
{
    public Location();
    public Location(double lat, double lng, LocationType type);

    public double Lat { get; set; }
    public double Lng { get; set; }
    public LocationType Type { get; set; }
}

public enum LocationType
{
    Degree = 0,
    Radias = 1
}

但我得到

  

无法将多个参数（来自＆＃39;和＆＃39;＆＃39;）绑定到请求中   内容。

当我使用Postman发送此PUT请求时，请求URL中发送了Id

api/Tickets/PutTicketDestination/00000000-0000-0000-0000-0000000000000

无法确定我在这里做错了什么
