JSon.Net Json到實體

我有一個實體，我用下面看到的數據庫設置實體作爲一個edmx文件。我也有一個JSon文件，我從edmunds.com 我正在使用JSon.net，並試圖解析JSon對象到實體中，並將Json的值保存到實體。JSon.Net Json到實體

我嘗試使用它的每個選項似乎都炸燬了我。任何人都可以請給我一個體面的例子，說明如何實現這一點，因爲它在這一點上令我瘋狂。

這裏是最近的錯誤，我得到無法反序列化JSON對象（即{ 「名」：「值」}）到類型「System.Data.Objects.DataClasses.EntityCollection` 1 [DealerTentSaleMVC.Models.Operation]」。反序列化類型應該是一個普通的.NET類型（即不是象整數這樣的原始類型，不是象數組或列表那樣的集合類型）或字典類型（即字典）。要強制JSON對象反序列化，請將JsonObjectAttribute添加到類型中。 Path'operations.Wednesday'，line 22，position 19.

該代碼發生錯誤。

  WebClient wc = new WebClient(); 
     string stws = wc.DownloadString(url); 

     JToken root = JObject.Parse(stws); 
     JToken dealerholder = root["dealerHolder"]; 
     DealerHolder convertedProducts = new DealerHolder(); 
     string dh = dealerholder.ToString().Replace("[", "").Replace("]", ""); 
     JsonConvert.PopulateObject(dh, convertedProducts, new JsonSerializerSettings 
                  { 
                   NullValueHandling = NullValueHandling.Ignore 

                  });

具體地說，它是發生在最後一行有

你可以建立一個反映您試圖反序列化JSON對象結構：

public class Result 
{ 
    public DealerHolder[] DealerHolder { get; set; } 
} 

public class DealerHolder 
{ 
    public string Id { get; set; } 
    public string LocationId { get; set; } 
    public Address Address { get; set; } 
    public string Name { get; set; } 
    public string LogicalName { get; set; } 
    public string Type { get; set; } 
    public string Make { get; set; } 
    public Operations Operations { get; set; } 
    public Contact Contactinfo { get; set; } 
    public string PublishDate { get; set; } 
    public bool Active { get; set; } 
    public string SyncPublishDate { get; set; } 
} 

public class Address 
{ 
    public string Street { get; set; } 
    public string Apartment { get; set; } 
    public string City { get; set; } 
    public string StateCode { get; set; } 
    public string StateName { get; set; } 
    public string County { get; set; } 
    public string Country { get; set; } 
    public string ZipCode { get; set; } 
    public double Latitude { get; set; } 
    public double Longitude { get; set; } 
} 

public class Operations 
{ 
    public string Wednesday { get; set; } 
    public string Tuesday { get; set; } 
    public string Thursday { get; set; } 
    public string Saturday { get; set; } 
    public string Friday { get; set; } 
    public string Monday { get; set; } 
    public string Sunday { get; set; } 
} 

public class Contact 
{ 
    public string Dealer_website { get; set; } 
    public string Email_address { get; set; } 
    public string Phone { get; set; } 
}

然後：

string json = .... go and fetch the JSON 
Result result = JsonConvert.DeserializeObject<Result>(json); 
// do something with the result, like for example enumerating over the 
// dealer holders collection

使用您的代碼得到錯誤無法反序列化JSON對象（即{「name」：「value」}）到類型'System.Data.Objects.DataClasses.EntityCollection'1 [DealerTentSaleMVC.Models.Operation]'中。反序列化類型應該是正常的.NET類型（即不是像整數的基本類型，而不是像數組或列表的集合類型）或字典類型（即Dictionary ）。要強制JSON對象反序列化，請將JsonObjectAttribute添加到類型中。 Path'dealerHolder [0] .operations.Wednesday'，line 1，position 404。 – scripter78
