Post到WebApi并获得结果HttpClient

我正在尝试将post发送到我的WebApi，然后将结果反序列化到我的对象。我用Windows Phone 8.1发送邮件。如何获得对象从我的Web Api发送?

我的构造函数:

public MyTravelsPage()
{
     Task getTravels = this.GetTravels();
}
internal async Task GetTravels()
{
    string uri = "http://localhost:6234/api/services/app/travel/GetMyTravels";
    TravelPositions travel = new TravelPositions();
    travel.UserGuid = UserIdentity.UserId;
    string x = JsonConvert.SerializeObject(travel);
    var stringContent = "";
    using (var client = new System.Net.Http.HttpClient())
    {
        // New code:
        client.BaseAddress = new Uri(uri);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        HttpContent content = new StringContent(x, Encoding.UTF8);
        var response = await client.PostAsync(uri, new StringContent(x, Encoding.UTF8, "application/json"));
        var p = response.Content.ReadAsStringAsync();
        var result = JsonConvert.DeserializeObject<Dictionary<string, string>>(p.Result);
    }
}

In p. result我得到这个字符串:

"{'"success'":true,'"result'":{'"output'":[{'"id'":1,'"userGuid'":'"334e5955-fe89-4a49-b8ab-f0b36575bd8d'",'"where'":'"Bukowno'",'"forMoney'":false,'"money'":'"'",'"peopleCount'":1,'"driverGuid'":null,'"longitude'":-122.188606,'"latitude'":47.622482},{'"id'":2,'"userGuid'":'"334e5955-fe89-4a49-b8ab-f0b36575bd8d'",'"where'":'"Krakow'",'"forMoney'":false,'"money'":'"'",'"peopleCount'":1,'"driverGuid'":null,'"longitude'":-122.188606,'"latitude'":47.622482},{'"id'":3,'"userGuid'":'"334e5955-fe89-4a49-b8ab-f0b36575bd8d'",'"where'":'"Warszawa'",'"forMoney'":true,'"money'":'"'",'"peopleCount'":2,'"driverGuid'":null,'"longitude'":-122.188606,'"latitude'":47.622482},{'"id'":4,'"userGuid'":'"334e5955-fe89-4a49-b8ab-f0b36575bd8d'",'"where'":'"Zakopane'",'"forMoney'":false,'"money'":'"'",'"peopleCount'":1,'"driverGuid'":null,'"longitude'":-122.188606,'"latitude'":47.622482}]},'"error'":null,'"unAuthorizedRequest'":false}"

如何从这个json字符串只得到"结果"值?

不幸的是，我的最后一行:

var result = JsonConvert.DeserializeObject<Dictionary<string, string>>(p.Result);

它没有给出字典…只有错误

关于更多信息，这是来自WebApi的对象

public class TravelOutput
{
    public List<Travel> output { get; set; }
}
public class Travel
{
    public int Id { get; set; }
    public Guid UserGuid { get; set; }
    public string Where { get; set; }
    public bool ForMoney { get; set; }
    public string Money { get; set; }
    public int PeopleCount { get; set; }
    public Guid? DriverGuid { get; set; }
    public double Longitude { get; set; }
    public double Latitude { get; set; }
}

public class RootObject
{
    public bool success { get; set; }
    public TravelOutput result { get; set; }
    public bool unAuthorizedRequest { get; set; }
}

var result = JsonConvert.DeserializeObject<RootObject>(p.Result);
