Question

我无法反序列化我的JSON。看起来不错。 Fiddler解析它，但我的实体看起来被卡在数据字段中。如何从“数据”字段中获取数据？我是在PCL内部这样做的，这是第一次这样做，通常我在JQuery中做过这个，从来没有任何问题。

从REST服务返回JSON：

{"ContentEncoding":null,"ContentType":null,"Data":[{"BusinessId":2,"CommunityId":2,"BusinessName":"TestBusiness1","Address1":"12 1st Ave.","Address2":"a","City":"Fargo","State":"ND","Zip":"58102","Phone":"7019283980","Email":"b1@falala.com","WebsiteURL":"google.com","Description":"First Test Business","Active":true,"HoursOfOperation":"Mon-Fri 8am-4pm","SelectedBusinessCategories":[4],"SelectedBusinessTypes":[2,3]},{"BusinessId":8,"CommunityId":2,"BusinessName":"TestHotel1","Address1":"600 50th St.","Address2":"a","City":"Fargo","State":"ND","Zip":"58103","Phone":"7013291780","Email":"b1@falala.com","WebsiteURL":"bing.com","Description":"First Test Hotel 4 boop","Active":true,"HoursOfOperation":"Mon-Fri 8am-4pm","SelectedBusinessCategories":[7],"SelectedBusinessTypes":[2]},{"BusinessId":9,"CommunityId":2,"BusinessName":"TestShop1","Address1":"349 32nd Ave.","Address2":"a","City":"Fargo","State":"ND","Zip":"58103","Phone":"7013298109","Email":"b1@falala.com","WebsiteURL":"something.com","Description":"First Test Shop 2","Active":true,"HoursOfOperation":"Mon-Fri 8am-4pm","SelectedBusinessCategories":[6],"SelectedBusinessTypes":[2]},{"BusinessId":10,"CommunityId":2,"BusinessName":"TestBusiness2","Address1":"24345 street","Address2":"a","City":"Fargo","State":"ND","Zip":"58104","Phone":"7014298490","Email":"b1@falala.com","WebsiteURL":"bing.com","Description":"Second Test Business","Active":true,"HoursOfOperation":"Mon-Fri 8am-4pm","SelectedBusinessCategories":[5],"SelectedBusinessTypes":[3]}],"JsonRequestBehavior":0,"MaxJsonLength":null,"RecursionLimit":null}

本地对象：

public class Item
{
    public bool Active { get; set; }
    public int ItemId { get; set; }
    public int CommunityId { get; set; }
    public string Name { get; set; }
    public string Phone { get; set; }
    public string WebsiteURL { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }   
    public string Zip { get; set; }
    public string Email { get; set; }
    public string Description { get; set; }
    public int Category { get; set; }
}

    public class Business : Item
{
    public int BusinessId { get { return this.ItemId; } set { this.ItemId = value; } }
    public string BusinessName { get { return this.Name; } set { this.Name = value; } }
    public int[] SelectedBusinessCategories { get; set; }
    public int[] SelectedBusinessTypes { get; set; }
    public string HoursOfOperation { get; set; }
}

调用REST服务并反序列化JSON：

List<Business> items = new List<Business>();
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri(WebServiceURL);
        var response = await client.GetAsync(Controller);

        var content = await response.Content.ReadAsStringAsync();
        dynamic datalist = JsonConvert.DeserializeObject<List<Business>>(content);

休息服务方法：

public JsonResult Get()
    {
        List<Business> businesses = new BusinessContext().Businesses.Where(b => b.Active == true).ToList();

        JsonResult json = new JsonResult();
        json.Data = businesses;
        json.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
        return json;
    }

这是因为你的模型应该是

public class RootObject
{
    public int BusinessId { get; set; }
    public int CommunityId { get; set; }
    public string BusinessName { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Zip { get; set; }
    public string Phone { get; set; }
    public string Email { get; set; }
    public string WebsiteURL { get; set; }
    public string Description { get; set; }
    public bool Active { get; set; }
    public string HoursOfOperation { get; set; }
    public List<int> SelectedBusinessCategories { get; set; }
    public List<int> SelectedBusinessTypes { get; set; }
}
