我有一个实体，我将实体设置为您在下面看到的数据库作为 edmx 文件。我还有一个从 edmunds.com 提取的 JSon 文件，我正在使用 JSon.net 并尝试将 JSon 对象解析到实体中并将 Json 的值保存到实体中。

我尝试使用的每一个选项似乎都让我大吃一惊。谁能给我一个很好的例子来说明如何做到这一点，因为这让我发疯了。

这是我得到的最新错误，无法将 JSON 对象（即 {"name":"value"}) 反序列化为类型“System.Data.Objects.DataClasses.EntityCollection`1[DealerTentSaleMVC.Models.Operation]”。反序列化的类型应该是普通的.NET 类型（即不是像整数这样的原始类型，不是像数组或列表这样的集合类型）或字典类型（即字典）。要强制 JSON 对象反序列化，请将 JsonObjectAttribute 添加到类型。路径 'operations.Wednesday'，第 22 行，第 19 位。

该代码正在发生该错误。

            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

                                                            });

具体来说，它发生在最后一行

您可以构建一个反映您尝试反序列化的 JSON 的对象结构：

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; }
}

进而：

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
