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
