上面是两个WPF控件，listBox和dataGrid。我能够从URL中的原始Json数据直接加载到listBox中。我想为dataGrid做同样的事情。我想从原始Json数据加载数据到dataGrid。请帮忙。

产品类包含5个属性。

后端::

private void TestConnection(object sender, RoutedEventArgs e)
    {
        string url = "http://192.168.167.1:8080/StudentOnlineRetailerWeb/rest/product";
        WebClient client = new WebClient();
        string reply = client.DownloadString(url);
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<Product>));
        listView.Items.Clear();
        List<Product> product;

        product = (List<Product>)serializer.ReadObject(client.OpenRead(url));
        foreach (Product temp in product)
        {
            listView.Items.Add(temp);
        }


    }

简单易用的方法从nuget使用jsonorm并通过（http://json2csharp.com/）

从收到的json创建数据层

Answer 2

为什么不从数据表加载，这很容易

DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

如何直接从C＃中的url原始Json数据加载dataGrid中的数据？
