如何反序列化oData JSON? [英] How to deserialize oData JSON?

问题描述

我正在尝试使用Northwind OData服务:

http://services.odata.org/V3/OData/OData. svc/Products?$ format = json

并将其反序列化为产品集合:

    using (var client = new HttpClient())
    {
        HttpResponseMessage response = await client.GetAsync(new Uri(url));
        ObservableCollection<Product> products = await response.Content.ReadAsAsync<ObservableCollection<Product>>();
    }

但是序列化器似乎不喜欢odata.metadata部分，并且那里有2个odata.type记录(不确定它们是什么).

有没有简单的方法可以做到这一点?

解决方案

使用 Json.Net

using (var client = new HttpClient())
{
    var json = await client.GetStringAsync("http://services.odata.org/V3/OData/OData.svc/Products?$format=json");
    var odata = JsonConvert.DeserializeObject<OData>(json);
}

---

public class Value
{
    [JsonProperty("odata.type")]
    public string Type { set; get; }
    public int ID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public DateTime ReleaseDate { get; set; }
    public DateTime? DiscontinuedDate { get; set; }
    public int Rating { get; set; }
    public double Price { get; set; }
}

public class OData
{
    [JsonProperty("odata.metadata")]
    public string Metadata { get; set; }
    public List<Value> Value { get; set; }
}

I am trying to use the Northwind OData service:

http://services.odata.org/V3/OData/OData.svc/Products?$format=json

and deserialize it to a collection of products:

    using (var client = new HttpClient())
    {
        HttpResponseMessage response = await client.GetAsync(new Uri(url));
        ObservableCollection<Product> products = await response.Content.ReadAsAsync<ObservableCollection<Product>>();
    }

But the serializer doesn't seem to like the odata.metadata part and the fact that there are 2 odata.type records there (not sure what they are).

Is there an easy way to do this?

解决方案

Using Json.Net

using (var client = new HttpClient())
{
    var json = await client.GetStringAsync("http://services.odata.org/V3/OData/OData.svc/Products?$format=json");
    var odata = JsonConvert.DeserializeObject<OData>(json);
}

public class Value
{
    [JsonProperty("odata.type")]
    public string Type { set; get; }
    public int ID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public DateTime ReleaseDate { get; set; }
    public DateTime? DiscontinuedDate { get; set; }
    public int Rating { get; set; }
    public double Price { get; set; }
}

public class OData
{
    [JsonProperty("odata.metadata")]
    public string Metadata { get; set; }
    public List<Value> Value { get; set; }
}
